摘要	In order to study the effect of gas extraction by high position borehole in goaf, and determine the best position of the borehole, it provides a reference for the selection of gas extraction target location by high position borehole in the future. Based on the goaf of 40113 working face of a mine in Fenxi Group of Shanxi Province, the gas migration model is established. and the gas extraction effect of high position borehole under different target strata is simulated by FLUENT. The results show that the gas concentration in the upper corner of the working face is reduced from 2.3% to 0.7% after using high position borehole to extract gas by compared with the non-extraction situation, which solves the problem of gas concentration exceeding the limit in the upper corner of the working face. When high position borehole of the distance from the floor of goaf is 26m,and the distance from the level of return air roadway is 25m, the gas concentration in the upper corner of the working face is 0.58%, and the gas concentration in the hole is the highest and the purity is the largest. © 2019 by Aussino Academic Publishing House.
