Alaska is widely known for its vast untouched wilderness, abundant wildlife, and its coal. Sam Weis explains in “The Local and Worldwide Impacts of Mining Alaska’s Coal,” that Alaska is home to an estimated 5.5 trillion tons of coal, which is approximately one-eighth of all the coal on Earth (25). The energy that comes from burning coal is in great need not only in the United States, but also all over the world. According to Gail West, in his article titled Alaska’s Coal Clean Burning and Abundant,” “Japan, South Korea, and Chile are three primary markets for Alaska’s coal exports (113). This dire need for coal has led many people wanting to turn towards Alaska as a primary source of coal. There is just one problem; the coal and the

The case describes the condition at the Arapahoe Pharmaceutical Company and its sales management structure. In the case, the Arapahoe Pharmaceutical Company has encountered important changes in the management structure of the sales division which has concerned the operations of the company. The change was started in order to beat the sales challenges that the company had been facing in

It is predicted that Australia’s carbon dioxide emissions would double if these mines were to be built, from 357.5 tonnes to 750 tonnes of carbon dioxide per year. Additionally, many of these mines will require additional train rails to be constructed for the purpose of transporting the mined goods to proposed ports on the coast of

Coal power is the cheapest fuel to power the ever growing population with Australian mining industry still putting in billions of dollars into a vast amount of coal projects never the less coal power is a fossil fuel, a fuel which takes hundreds of year to form so the future of coal is undetermined. Coal is a reliable power source but one of the many concern with coal is the mining process used to remove it from the ground. Ecological effects are developing worries for the industry, with the carbon emissions possibly contributing to global warming.

Coal’s reputation has become as black as coal itself, but without it the quality of life that hundreds of millions of people enjoy today would not be possible. Coal has been used in many ways throughout history and it will continue to be a vital resource in supplying the energy needed to fuel an energy hungry world. Research cited throughout this paper suggests that coal is an energy source for the future because it is stable and reliable with abundant reserves, it is the most affordable and efficient fuel source used to produce power, and because of new clean coal technologies, coal can be burned with minimal to no damage to the environment.

Coal (n): A combustible black or dark brown rock consisting mainly of carbonized plant matter, found mainly in underground deposits and widely used as fuel. This little rock is what keeps 39% of our nation running. 10% of that coal comes from stripping the Appalachian mountain range of her beautiful peaks in a process called strip mining- or, more popularly, Mountaintop Removal. Coal is considered a non-renewable energy resource, meaning once it’s depleted, it will not return for millions of years. Once it's gone, it's gone. These non-renewable sources are found deep underground. Coal needs to be mined out, either by machine or by manual labor. The use of and the process in which we procure coal is a detriment to both the environment and the people in said environment. It is dangerous to the workers within the mines, the flora and fauna around the sites, and the surrounding communities.

While coal mining has the advantage of providing employment, cave ins and explosions are common in mining. This leaves people’s lives in danger. There is also a risk to not only those working in the mines, but also those living close to dig areas. Constant exposure to chemicals can result in lung cancer, respiratory diseases, heart failure and low birth

and the impact of its use on the environment and the habitat around the coal mining sites.

Helgi Valur Fredriksson, Hamid Jafari (2010-05-21). To improvement the target company’s manufacturing process by applying lean principles, including using and analyzing the internal value stream mapping. As more and more companies have paid attention to implement lean thinking in their manufacturing process, the value stream mapping played an important role for many companies to make a transition from their traditional production systems to lean systems. The content and resources of this master thesis come from an American furniture company named KAMA which mainly produces office furniture with different components. Although there are various types of products, the authors merely focus on the office chair products. This research is an attempt

But there are also many detrimental factors as well, since the production of coal results in air pollution, sulfur dioxide emission, carbon dioxide emission, acid rain, and hazardous waste [4]. These environmental problems are due to both the mining of coal and coal production plants. Many issues arise with the mining of coal. Firstly, the safety of miners is put at risk as they descend hundreds of feet below the surface of the Earth. After many years in this field of work, many miners develop black lung because of inhaling the coal extensively. Secondly, the extraction of coal is very costly due to the machinery needed along with the transportation of the coal after it has been mined to the various factories that are able to extract the sulfur impurities in coal and burn the coal for energy [5]. New methods have been developed to help with some of the issues relating to coal production. To rid the surrounding environment of toxic pollution, emission-scrubbing

When coal is being transported by rail it should be placed in dead storage in order to minimize air pollution due to dust, this involved compacted and sealed pile not susceptible during wind activity. when transporting coal, the unit/agency should ensure that trains is showered with water with adequate system before leaving the storage yard, the coal should be covered with tarpaulin or any other effective measure/device. Another safety precaution that one should adhere to when transporting coal via rails is to ensure that trains are not overload because it will cause spillage during transportation

After the coal has been removed form the earth, it is still not ready for use; it must first be refined. Coal must first be separated form foreign materials, for example other minerals, to be considered useful to us. One way of doing this is called coal washing. The coal is first crushed into smaller pieces, and then a liquid is used to separate the coal based on density. Coal that is higher in density harbors more ash, so is left behind, whereas low-density coal has contains little ash and is more desirable. Another process to separate coal from foreign materials is call dry-shaling, which works without the use of liquid. After being separated, coal can be processed into coke, and eventually steel. When coal is transported, it can be by means of truck, train, or ship, and can go nearly anywhere. Truck and train transportation are the cheapest forms, particularly train if you are shipping a great amount, and ships are used for overseas transport.

Toyota today is one of the leading lean example in today’s manufacturing market. Starting back in the 1930’s with the idea of Just-in-Time to cut down cost in waste from overstocked storage rooms to a better efficient assembly lines who produced what was needed at a certain time. The Kanban system is one of the most used methods that the Japanese found during the 1950’s during a trip to United States in a super market.

The mining industry has seen an explosive growth from the past few decades. It has played an important role in economic growth, infrastructure development and a raise in the living standard of the whole world. According to the Australian National Accounting System, the mining sector has made contributions of 9.8% GDP growth to the Australian economy between 2008 to 2009 (Australia Bureau of Statistics, 2012). However, the mining industry has caused many environmental issues such as adverse effect to air, land and water quality and continues to affect global environment as a whole. According to the World Health Organization, it evaluated that 25% of worldwide death are directly associated with environmental pollution (Blacksmith Institute, n.d). This essay will outline the environmental issue raised by the mining industry with pinpoint focus on the effects to air, water and land. It will also provide strategies for mining companies to improve the environmental conditions.
