回采工作面大型断层产状综合探查分析

为避让小煤窑采空破坏区,腾晖煤业2-202工作面布置在了断裂构造发育区,工作面内部包含落差6~8m的顺煤层走向断层。矿井采用物探加两顺槽钻探窥视测斜的方式,准确圈定了断层落差及延伸情况,减少了煤炭资源浪费,并为后期安全回采提供了准确可靠的地质资料。

Comprehensive Exploration and Analysis of Large Faults in Mining Face

In order to avoid the gob damage area of small coal mines,Tenghui Coal Industry 2-202 working face is Arranged in the fracture structure development area,and the inner part of the working face contains the coal seam strike fault with a drop of 6~8m.The method of geophysical exploration and two parallel drilling is used to survey the slope,which can accurately delineate the fault drop and extension,reduce the waste of coal resources,and provide accurate and reliable geological data for the later safe mining.
