摘要：

In this paper, we take the W2303 working face in Sihe mine, Shanxi Province, China as a project case, where it has been met with three thrust faults. The occurrence regularity of coal gas near the faults are studied, and the gas content around the faults are measured. The comprehensive measures of gas extraction are carried out, including the wear layer and in-seam kilometer directional feathery drilling combined with multi-branch technique. The gas threat around underground thrust faults is effectively eliminated. This technical engineering practice has a good guiding significance to other similar mining areas.
