摘要
为了加强对综采工作面采空区导水裂隙带发育高度的研究,以五轮山煤矿1801综采工作面为例,采取现场实测与理论计算相结合的方法进行了研究。通过规程方法计算和钻孔电视探测得出了该综放工作面的导水裂隙带发育高度。最终确定五轮山煤矿8号煤开采后的冒落带高度为9 m左右,8.07 m细砂岩为关键层,关键层之上的岩层将产生离层裂隙,裂隙带最大高度为26~35 m左右,导水裂隙带高度约35~44 m。本文成果为8煤开采工作面的安全生产提供了理论支持和技术指导。
In order to strengthen water-flowing fractured zone distribution research in 1801 fully mecha-nized working face of Wulunshan coal mine, the method of combination of field measurement was carried out. Through theoretical and measured method, the height of caving zone of Wulunshan is about 9 m. And the height of fracture zone is about 26 - 35 m. So the height of water-flowing fractured zone of Wulunshan coal mine is about 35 - 44 m. The research results about height of water-flowing fracture zone of Wulunshan coal mine provide theoretical support and guidance on the safety production of the fully mechanized mining face.
