摘　　要：随着北京地区煤矿的陆续关停,门头沟区清水镇达摩沟废弃煤矿遗留下大量煤矸石,不仅造成安全隐患,而且对矿区生态环境带来种种负面影响。采用电镜扫描、X射线衍射分析、颗粒分析、物理力学性质测试等方法,对达摩沟废弃煤矿煤矸石宏观结构、微观结构、矿物成分、物理力学性质等进行了研究,提出了煤矸石综合利用与开发的建议,也为该地区废弃矿山地质环境保护与治理恢复提供了基础数据和设计依据。With the coal mines in Beijing successively closed,the abandoned Damogou Mine in Qingshui Town,Mentougou District left lots of coal rejects,which would not only cause the potential safety hazard,but also would have different negative impacts to the ecological environment in the mining districts.With the scanning of the electron microscope,X-ray diffraction analysis,particle analysis,physical-mechanical property measurement and other method,a study was conducted on the macrostructure,microstructure,mineral composition,physical-mechanical properties and others of the coal rejects from the abandoned Damogou Mine.A proposal on the comprehensive utilization and development of the coal rejects was provided and could provide the basic data and design basis to the geological environment protection and restoration for the abandoned mining area.
