A set of mathematical models was derived and evaluated on 5 years of runoff and pollutant data in the New River, Tennessee. The six watersheds used in the study ranged in size from 429 to 2765 acres. All but one watershed had been or was undergoing contour coal strip mining. The remaining watershed was in forest.
2 methods = room and pillar mining. removes large area of coal and leaves behind coal pillars that support the mine's roof. Effects of Subsurface Mining less land disturbance. very dangerous. most of the coal is still left underground. risks = roof collapse, build up of toxic gas, & lung disease.
mental effects of the method-strip mining-by which surface coal is extracted. This study amounts to a quantitative cost-benefit analysis of the Surface Mining Control and Reclamation Act of 1977 (SMCRA). Incidence and welfare effects of SMCRA are developed within the context of a multi-sector model of the U.S. coal industry.

Extraction of mineral resources is the backbone of the national economy in many developed and developing countries of the world. However, the exploitation can have many negative impacts on the immediate environment of the exploitation sites. In this study performed on some mining areas of the Moroccan Anti-Atlas, four principal negative effects were detected: effect on the physiognomy, on ...

This case study focuses on the costs of the environmental and social effects of coal mining in South Africa, undertaken for export to the Netherlands. Coal mining imposes many external costs on its surroundings and the people who live in it. Some of these can be quantified by estimates, others are difficult to estimate. Coal mining is
Along with studies regarding the correlation between uranium miners and lung cancer there have been other studies that suggest that miscarriages, birth defects, reproductive, bone and gastric cancer along with heart disease deaths have also been identified as related health effects of uranium mining (Churchill 1986, Gofman 1981, McLeod 1985).

The objective of this study is to determine the quantitative relationships between change in peak and mean daily flow and the associated coal strip mining in a given watershed. The study of the effects of strip coal mining on the watershed hydrologic changes is a system cause-and-effect . Get price
provides and analyses a simulation model to derive the optimal strip width for pre-strip activities. Case study data obtained from an established leading coal producer in the Bowen Basin was implemented into a pit simulation model to assess the effect of pre-strip width on the overall pit economics. Pre-strip .
All surface or strip mining first removes the overlying vegetation, soil and underground rock layers in order to expose and extract coal from an underground seam or coal deposit. Responsible surface mining attempts to limit the side effects of this removal through several basic steps:
