大采高综采工作面跨断层开采

Cross-fault mining on fully-mechanized mining face of large mining height

为了解决在铁法煤田复杂的地质条件下,提高综采工作面回采率的问题,大隆矿在S1905大采高工作面尝试了跨断层开采的新工艺,工作面从9#层煤直接跨过落差接近26 m的断层开采到7#层煤,使工作面多向前推进了114 m,多回采原煤15.5万t,这项工艺为综采工作面适应复杂的地质条件,积累了经验,拓宽了综采工作面的应用空间。

In order to improve recovery rate of fully-mechanized face under complex geological conditions in Tiefa Coal Field, a new technology of cross-fault mining on the face of S1905 large mining height was tried in Dalong Coal Mine. Fully-mechanized mining face moved directly from 9^# layers to 7^# layers with nearly 26 meters fault, with a progress of 114 m and recovered raw coal of 155 thousand t. This technology helps accumulate experience for fully-mechanized mining face to adapt to complex geological conditions and widens application space of fully mechanized working face.
