ENVIRONMENTAL DAMAGE AND COUNTERMEASURES IN CHINESE COAL MINE AREAS

摘要

The paper discusses three aspects of the ecological environmental damage in China: ground subsidence due to underground coal mining, pollution of mine refuse from underground, and release of fly ash from power plants within coal mine areas. The paper proposes the comprehensive countermeasures for solving these problems. The author puts forward several ways and applications of disposal which could help alleviate the problems, and introduces the subsidence prediction principle in long wall mining. This technology calculates the subsidence, displacement and deformation at every point according to mining schedule. It provides very useful tool for subsidence control. Finally, the author provides some suggestions to improve the environment in Chinese coal mine areas.
