论潞安化工集团所属煤矿地表压煤的解决途径

Discussion on Solutions to Coal under Surface of Coal Mine Subordinate to Lu'an Chemical Group

据不完全统计,潞安矿区9座主体矿井(不含李村矿井)仅村庄压煤量一项就达2.65×109 t。“三下”压煤已经成为制约潞安矿区发展的一个严峻且紧迫的问题。目前,中国已经有多家矿井采用柱式体系采煤法或充填开采法成功开采村庄下、铁路下和河流下的压煤。简要介绍了适合潞安矿区的“三下”采煤技术,以期为日后相关工作提供参考和借鉴。

According to incomplete statistics,the 9 main mines in the Lu'an mining area(excluding Licun Coal Mine)have coal under villages of 2.65×109 t.The"three-under"coal has become a severe and urgent problem restricting the development of the Lu'an mining area.At present,many mines in China have successfully exploited coal under villages,railways and rivers by using pillar mining or filling mining.This paper briefly introduced the"three-under"coal mining technology suitable for Lu'an mining area,in order to provide reference for related work in future.
