矸石回填复垦技术在许厂煤矿土地治理中的应用
|
摘要
煤矿的生产建设有力地促进当地经济发展和社会进步,但同时对当地的地质环境与土地资源造成一定程度的破坏和影响。为了缓解矿产资源开发与生态环境保护协调发展的矛盾,对塌陷区进行有效的治理,避免和减少对矿区生态环境的破坏;以许厂煤矿矸石复垦区为对象,通过矸石物性特征和矸石需求量分析,评价矸石用于塌陷区回填和复垦的可行性,并应用于农田塌陷区及积水区治理,取得了很好的社会、环境和经济效益。
The production and construction of coal mines strongly promote local economic development and social progress, and at the same time, it also causes a certain degree of damage and impact on the local geological environment and land resources. In order to solve the contradiction between the coordinated development of mineral resources development and ecological environment protection, and effectively control the subsidence area to avoid and reduce the damage to the ecological environment of the mining areas, this paper takes the reclamation area of Xuchang coal mine as the object, based on the analysis of the physical property and the demand of gangue, the feasibility of using gangue to refill and reclaim the subsidence area was evaluated, and the gangue is also applied in the subsidence area of farmland and water-accumulating area. Good social and economic benefit has been obtained.
