Earth and Environmental Science Environmental Impact Statement By Byron Smith Actual Development “Hume Coal Mine “ In the Berrima area located in the NSW southern highlands there has been a proposed coal mine. This coal mine will consist of large stockpile near Berrima (town centre), train loading facilities, a train line and an underground mine. The Hume coal mine is too “extract 3.5 million tonnes of coal… in the next 19 years”. The public have protested about this proposed mine as…

When the oxidation was completed, the depth of the oxidized zone was around 50m from the ground surface (Forrestal, 1990). Cerussite was found as the dominant mineral while zinc was mostly exhausted. The orebodies’ bedded nature remained the same within the oxidized zone but the rocks are filtrated outside the oxidized zone. In addition, this oxidized ore were generally used for ancient production of mining a long time ago. But nowadays, this oxidized ore would only be used for smelter flux.…

Abstract This paper details the causes and extent of the pollution at Tar Creek Superfund site in Ottawa County, Oklahoma. This Superfund site is a heavy metal-contaminated area that was created by the aftermath of zinc and lead mining operations throughout the 1900s. The pollution has put local inhabitants at risk of different health issues, and while risk assessments have shown that no significant health risks are obvious compared to the rest of the state of Oklahoma, blood lead levels have…

however, comes with certain drawbacks that need to be fixed or improved upon. One drawback in particular is the disposal of ‘industrial waste.’ In this paper, we will be tackling two of the most important sources of industrial waste: E-waste and mining waste. E-Waste With the development of technology in our everyday life, people tend to own more novel and advanced electronic appliances, discarding the old ones. It is estimated that each year the discarded electronics worldwide weigh about 50…

Rockbolts as a ground control technology are just one in the very long list of ground control technologies that exist in mining and civil applications. The simplicity and reasonable cost associated with rockbolts are the primary driving forces for the research causing their wide variations for numerous public and private uses. The ease of calculation and implementation also makes rockbolts a go to option for engineers who would rather spend more time calculating other variables during a job…

64% of the state’s electrical production (Reese and Loughlin, 61).” Mining has caused severe environmental impacts ranging from the toxic chemicals seeping into the watershed, the altering of landscapes, and large amounts of waste (Reese and Loughlin, 61). New laws have been developed in order to reverse the negative trends from mining, which include the following: Abandoned Mine Land law, Open Cut Land Reclamation Act, Surface Mining Control and Reclamation Act of 1977 (Reese and Loughlin, 62) …

Impact of Mining on Australia’s History Since the early eighteenth century, mining in Australia has had a pivotal impact on the development of the economy and environment, which has successfully continued unto today as one of Australia's most fundamental industries. In particular, the Glen Osmond silver-lead mines in South Australia have not only produced significant amounts of silver lead since its foundation, yet has also been recognised as the establishment of mining in Australia, which has…

regions. To achieve greater raw material security, Tata Steel is also pursuing various mining projects To foster inclusive growth, Tata Steel encourages local buying, particularly from small entrepreneurs and Non Governmental Organisations, whose revenue flow benefits the local community and mainstreams disadvantaged…

For as long as I can remember, I have had a burning desire to earn my bachelor’s degree, a goal which has been set for countless years. My future goal is to complete my bachelor’s degree with an emphasis in math and English, with the ultimate goal to teach algebra at any level between the seventh and tenth grades. My eighth grade algebra teacher helped me achieve an understanding of algebra that I never knew existed, instilling in me a desire to pass on an understanding of and an excitement…

Sealcoat is a product that helps prevents corrosion on black top, which is caused from multiple factors such as the rain, which contains a low acid count. Plowing is also a large factor and one of the harshest reasons upon corrosion. Lastly would be tree roots, weeds and grass. Blacktop is very durable but at the same time it is very fragile. Taking care of a blacktop driveway or parking lot is a major investment that everyone should always consider into when they look to upgrade or maintain a…
