建筑物下采煤技术现状及发展

我国建筑物下采煤的研究从20世纪60年代开始,先后在本溪、鹤壁、抚顺、枣庄、峰峰、蛟河等矿区进行试验,取得了成功的经验和宝贵的监测资料。在综合分析大量文献的基础上,全面总结了充填开采、条带开采、三步法、协调开采、离层注浆等主要建筑物下采煤方法和井上建筑物的保护措施,并阐述了建筑物下采煤的发展趋势。

Present Situation and Development Trend of Mining Technology Under Buildings

Experimental studies on coal mining under buildings in China started since 60's of last century successively in Benxi,Hebi,Fushun,Zaozhuang,Fengfeng,Jiaohe and so on,and successful experience and precious monitoring material had been obtained.Based on full literature search and comprehensive analysis,the paper presents an overall summary of the main mining methods which include cut and fill mining,strip mining,3-step mining,coordinated mining,filling the collapsed cavities in over lying strata etc,and elaborates the future research direction of mining under buildings.
