Abstract：In order to study the reasonable position of high level drainage roadway,according to the mining conditions and overburden characteristics of 13-1 coal seam in Liuzhuang Coal Mine Huainan mining area,theoretical calculation and similar simulation experiment and construction observation were carried out,to study the reasonable position and drainage effect of high level drainage roadway.The results show that 13-1 coal seam working face caving zone height is about 4 times of mining height,fractured zone height is about 16 times of mining height,reasonable position of the high level drainage roadway is about 42m above the coal seam roof.And it is more reasonable using similar material simulation test results to determine the position of high level drainage roadway.
