摘要
露天煤矿的开采对矿区生态环境造成了严重破坏,特别是大量剥离物形成的排土场,占用了大量的土地资源。生态恢复作为一项有效的采矿废弃地治理措施,随着采矿业的发展成为这一领域研究的重点。露天煤矿排土场的复垦对于改善矿区生态环境意义重大。本文介绍了露天矿排土场对环境的影响和排土场复垦治理技术,研究了某露天煤矿排土场的复垦现状、复垦方式与效果,提出了矿区排土场生态恢复的建议。
The open-pit coal mining has seriously damaged the ecological environment of the mining area,especially the waste dump has occupied many land resources.With the development of mining,ecological restoration has been the research focus in this filed as an effective measure of wasteland treatment.The reclamation of waste dump is significant to improve the ecological environment of the mining area.In this paper,the environmental impact and reclamation techniques of mine waste dump is introduced,a coal mine is taken as an example and its reclamation status,reclamation mode and effect is studied.Then suggestions about ecological restoration of mine waste dump are made.
