Effects of Coal Mining on Environment Term Paper

It causes dangerous damages on water, soil, animals, plants and other part of ecosystem. Coal mining affects the ground water by contaminating it. Contamination will happen when the amount of excess water that is used in mining is release into the drainage system and seep by the soil.

Effects of surface coal mining and land reclamation on

2019-4-1  Coal mining often causes drastic changes in the soil profile and the loss of soil organic carbon and nutrient pools (Indorante et al., 1981). As a direct result the soil system can suffer substantial and long-lasting damage, which negatively affects land productivity and

A simulation experiment study to examine the effects

2021-2-9  Noise pollution in coal mines is of great concern. Personal injuries directly or indirectly related to noise occur from time to time. Its effects impact the health and safety of coal mine workers. This study aimed to identify if and how the level of noise impacts miners’ safety behavior in underground coal mines. In order to study the influence of noise on miners in the mining industry, we
