黑龍江省大中型煤礦礦山地質(zhì)環(huán)境評(píng)價(jià)
[Abstract]:Heilongjiang Province is rich in coal resources, the coal economy has made great contributions to the economic development of the province. However, unreasonable exploitation and utilization have caused a series of mine environmental problems, resulting in serious pollution and destruction of ecological environment. In this paper, the index of five variable layers is quantitatively described by 14 factor layer indexes, which constitute the index system of geological environment evaluation of large and medium-sized coal mines in Heilongjiang Province. After the weight of each index is determined by AHP, the large and medium coal mines in Heilongjiang Province are evaluated. Combined with the evaluation results, the geological environment problems of large and medium-sized coal mines in Heilongjiang Province are divided into three types: serious area, more serious area and general area. At the same time, the restoration and treatment of mine geological environment is divided into three parts: the area of mine geological environment to be restored, the key area of mine geological environment prevention and control, and the general restoration and control area of mine geological environment. In this paper, the types and present situation of geological environment problems in large and medium-sized coal mines in Heilongjiang Province are preliminarily found out through investigation and evaluation, and the inducing factors are analyzed for the rational exploitation and utilization of mineral resources. The countermeasures and suggestions are provided for the protection of the ecological environment and the restoration and development of the mining area.
