综采工作面过大断层延面开采

Extended the Face Mining of Crossing Large Fault in Fully Mechanized Working Face

介绍了峻德煤矿综采三区采煤队,针对采场地质条件,采取可行的技术安全措施,穿层爬坡开采,顺利通过落差6.5～12 m大断层,取得了过大断层和硬帮顶板管理经验,提出了集中过斜交断层,通过采用旧皮带保护设备并加强设备检修等安全质量管理方法,为类似条件工作面过大断层开采提供了借鉴。

Introduces the mining team of fully mechanized third area in Junde coal mine,according to the geological conditions,adopts feasible technical safety measures,crossing layer climbing mining,successfully pass the large fault of difference of level of 6.5 ～12 m,achieves the experiences of passing the large fault and hard side roof management,puts forward the safety and quality management methods that concentratedly pass oblique fault,by using the old belt protect equipments and enhance equipment maintenance and so on,for the similar working face passing the large fault mining provides a reference.
