Resources and Environment Harmonics(Green) Mining and Its Technological System

Abstract

The impact of the coal resources exploiting on environment is not only a focal point of great attention in the world but also one of the important issues influencing on the social and economic development strategy in China.Based on the request of coal industry development,the necessity and significance of researching the coal resource green mining is expounded,and the connotation of green mining is particularly explained.Companied with the discussion on the technological system of coal resource green mining,the key problems and research status are analyzed in depth,which include water preserving mining,simultaneous extraction of coal and coal-bed methane,partial extraction and backfill mining,underground discharge of partial rock refuse and underground coal gasification,etc.And the corresponding suggestions for a further research on green mining are put forward.
