Introduction into Mining


Mining has long been an industry the nation depends on. So many of the things we depend on today originate from mines. That may be hard to believe but think about it this way, “if it can’t be grown, it must be mined.” This quote is used to sum up what mining is about. Mines provide the world with raw materials that then produce the goods and energy we use and depend on every day. You can’t grow our laptops, televisions, cell phones, jewelry, or electrical wire. All of the components inside of these things use materials that originated from mines. The electricity that we use to light our homes and power cites comes from a black rock known as coal. Although it does not power every home it still provides much of the world’s energy. Mining is even involved with our agriculture and construction industries. Without mining, many industries would be non-existent. In reality, much of the globe’s industries are connected to mining in some fashion.

Introduction into Mining Engineering


With the impact that the mining industry on the global market, there has to be people that plan and manage these kinds of operation and this where mining engineers come in. Engineers do many different tasks associated with the operation of the mine. They can be involved almost anywhere in the mine. They also move up in their jobs. They have the opportunity to become a mine manager because of the experience mining engineers have. To gain this experience, engineers work in two main areas of a mine which are production or the engineering office.

Production


They can work in the production area of the mines where they work as the job foreman and make sure the miners are mining the correct area and following correct procedure. They can also be in the preparation plant making sure the ore or raw material is being processed is being correctly processed. The goal of the production plan is to maximize production which is the same for the mine itself but also maximize recovery from the raw ore. Depending on the material being mined, this could be a complicated process. There are different stages of crushers, grinders, floatation tanks, slues boxes, dryers, and load out facilities. Engineers design the whole process.

Engineering


With the actual engineering side of the operation, mining engineers work on a variety of tasks. They can work on surveying which is critical for a mine. In a mine, surveying is used to, of course, mark property boundaries, but it also helps to mark the geography of the land. During the mine reclamation stage, the land must be returned to previous conditions. Surveying is also used to determine the position of the miners underground. Since there are no landmarks underground, surveying is critical to make sure the mine is progressing in the correct direction. Engineers also look at the rock formations underground to determine the method of supporting the roof. Supporting the roof is necessary for the safety of the miners. They also design ventilation systems that provide miners underground with clean, fresh air. Ventilation of the mine is also necessary to remove the harmful, combustible gasses that come from the ground. Engineers design the electrical systems that power the equipment needed for mining. The power system is also used for the ventilation fans, lights, and conveyor system.

Business Decisions


You may not think of an engineer making business decisions under the mine manager. But in reality they advise the manager on what to do. Engineers look at samples to determine if it feasible to mine in that location or another on the property. This is critical to the overall profitability of the mine. They have to determine were the richest deposits of the mineral ore or coal is and make decisions from that. Once they have located the deposit, they must determine the size of it. This is called reserves. The reserve is what determines the life of the mine. If the reserve of mineable material is large, the mine will be able to stay in one location. The reason I say mineable material is because some material is in to small of a deposit and cannot be feasibly recovered. If it is feasible to mine, then engineers begin the mine planning process. This process determines the mine down to fine details. They must first decide on the type of mine. The two most basic forms are surface and underground mining. There are other classifications within surface mining and underground mining but for now we will stick with the two main ones. They must then form the plan for water runoff, mine ventilation, mine direction and size, and the machinery and power needed.

The Importance


Mining provides the globe with the raw materials that then are turned into the goods we depend upon today. Engineers play an important role in mining because of all the knowledge and information they provide. Engineers have a deep understanding of the mining process and the planning and regulations that come with it. With this knowledge, engineers help mining companies become more profitable. In today’s market that is a major concern. We will talk about this in another section. They also help them to become safer. This may seem like a general statement but it rings true for almost all mining companies, regardless of the material being mined. There are numerous safety regulations in place that govern the mining industry. Mining engineer’s help to ensure the mine follows these regulations but they also look for improvements within the mine the put the mine above the regulations. This makes employees feel better when they come to work as well as reduces the fines and injury rate of the miners.

The Problems


The mining industry is critical for the development of the nation. It will always be present because of the shear need for earth’s resources. Many people don’t see mining as a necessary operation. People think of the mining industry as an industry that ruins the land and pollutes the waterways and the atmosphere. They believe mining is unsafe because of the earlier accidents in mining. This is the same perception that our current governmental administration has.

Issues with the Public


The public tends to point fingers at industries that they think pollute the environment. There are “numerous environmental groups, who are uninformed, attacking the industry.” This was a response that Colton Parsons gave to me after I asked him what was hurting the industry the most. This is evident in the amount of groups that are out there that protest against the mining industry. Kristin Floyd also responded to the same question saying “the public still has the same perception that mining today is like mining in the past. They don’t understand that technology and awareness have improved the industry in many ways.” This is why many people are in opposition of mining. They still believe the stereotypes that mining is one of the most pollutant industries. They also believe that mining is just as dangerous as before. They think it is a common occurrence that miners are being injured, killed, and trapped in mine cave in’s.

Reality for the Public


The truth is the current perceptions of mining are just stereotypes. They are far from the truth. Just a Kristin said, “Technology and awareness have improved the industry.” The mining industry does not use the same equipment as they previously have. Miners use continuous miners to increase production and lessen the chance for miners to get injured when digging for coal. These machines allow the miners to use a hand held control box that is connected by a cable to the machine. Having the miner run the machine remotely lessens the chance they will be struck by a falling rock from the roof or being trapped in between the machine and the walls.  Mines also use mucking machines the scoop the coal or ore and load it into shuttle cars. This reduces the physical strain on the miner’s body. Many companies have also created procedures that improve the safety of the miners.  There are also roof bolting machines that help support the roof the prevent cave in’s in underground mines. Many of the machines I just mentioned are powered by electricity. In surface mines, the larger shovels are also powered by electricity. The electrical system of a mine helps to reduce the pollution of the environment and it helps to ensure the safety of the miners will clean air if they are underground. Underground mine ventilation has changed over the years to.  Mines now use large fans to push fresh air into the mine and this also pushes the harmful gasses out.

Issues with the Government


Mining engineers plan and monitor many things within a mine. One of the biggest things they do is make sure government regulations are followed. This can be one the toughest jobs because there are so many. According to Kentucky Educational Television or KET for short, “As long as 10 years can elapse between the start of planning a mine and mining the first ton of coal.” This is an example of the amount of rules and regulations that the mining industry must follow.  This is just for the permitting process. There are numerous regulations that are in place when extraction of the coal or ore is taking place. As is talked about earlier, ventilation is a key area. There must be a certain level of fresh air available in a mine. Also dust control is a major problem. During the extraction of the ore from the ground, dust is created from the breaking of the ground. There are regulations of the level of respirable dust that can be present. Respirable dust is the dust that is small enough in partial size to be inhaled. There are also regulations in place for water runoff on the mine. This is some of the more general regulations that mining engineers have to deal with.

Results from the Regulations


Don’t get me wrong, regulations are needed. This is true for any industry. Without some regulation many people would be in danger just going to work. But regulations surrounding the mining industry is different the other industry regulations. Many companies in the coal mining industry are struggling to survive because of these regulations. Colton Parsons told me, “Prepare for a career in mining commodities other than coal in case the coal industry is regulated into extinction.” This was in response to a question I asked about what students should expect when looking for a job near graduation. These regulations are strangling the coal industry. It is also hurting other industries as well but coal may be the most effected. Looking at data from the US Census Bureau, all of the major divisions of mining have experienced a cut in employment because they can’t afford the keep employees. This is in connection to the price of the commodity being sold. If the price is down, mining companies will not make as large of a profit if prices are high. According to the US Energy Information Administration, within six months, from November 2008 to June 2009, coal prices were cut by over half. They have remained at this level since. This is the same time when the current administration took office for the first term. The recession began and so did the governments grip on the coal industry and other mining industries as well.

The Effect on Students


You may be thinking what this has to do with students in college. The answer to that is it greatly affects students. Within the mining engineering field, there is a need for mining engineers. Many of the mining companies are willing to provide internship opportunities for college students. This introduces students into the field with hands on activities that they would be doing on the daily job. Colton Parsons stated,” internships are vital to future employment.” Many companies tend to continue to offer students internships after they have interned once with the company. After several internships, many companies offer the students full time employment opportunities with the company upon graduation. But since the recession has started, it has become harder to find employment. There is still a need for mining engineers but the economy is not favorable for mining companies to hire interns. I have had this experience as a freshman in mining engineering. Many companies come to the school recruiting students for these internship opportunities but they also have a narrow filter for the students they want. Many companies do not want to hire freshman because they don’t have the mining experience like sophomores, juniors, and seniors do. This makes finding an internship difficult. This will also affect the sophomores next year because of the lack of work experience.

Education at the University


The mining engineering department at the University of Kentucky provides students with a well-rounded education. The mining engineering program here is an accredited which means the curriculum has been approved by a higher authority in the mining engineering field. This helps to improve the quality of education. Comparing the mining engineering department curriculum of the University of Kentucky to a rival mining engineering school, West Virginia University, Kentucky’s curriculum closely resembles West Virginia’s. These schools are part of the group that is at the top of the education field for mining engineering. I asked Colton Parson if the University of Kentucky had prepared him for a career in mining engineering and he said, “Yes UK has a rigorous engineering program.” I also asked Kristin Floyd the same question and she said,” I feel that UK has adequately prepared me for a mining career. Professors are always willing to help and you get exposure to many different aspects of the mining industry. They may not all be an in-depth analysis of each aspect but they are adequate. As with any degree and profession someone pursues there is only so much that can be learned in the classroom. However, the emphasis put on labs and hand on experience during the school year has allowed for what is learned in the classroom to be translated to what one would experience in a real profession. Overall, I feel prepared.” The university here does a great job at teaching and preparing students for the mining engineering field.

Why keep the Major


The mining engineering major here at the University of Kentucky is not the largest engineering filed. Many students do not pursue a degree in mining engineering or they transfer out of the program after one year. Officials at the university may think the program is not needed because of this reason. This is where they would be wrong. The major is a vital major in the engineering department and for society as a whole. The mining program here is competitive with the programs from other schools and it helps students find employment after graduation. Mining is a vital part of the function of our nation and mining engineers play a major role in this. The engineers provide a wealth of knowledge that allows companies to run smoothly and profitably while also helping to expand the company with a well detailed plan. The major, and the opportunities that go with a degree from the department, open up many doors for graduates. That is why the mining engineering major should keep kept at the University of Kentucky.
