中文摘要：

为了研究高抽巷合理的布置位置,根据淮南矿区刘庄煤矿13-1煤的实际开采条件和上覆岩层特征,采用理论计算、相似模拟试验和现场施工观测等方法,研究分析了高抽巷合理的布置层位和对瓦斯抽采效果的影响。结果表明：13-1煤工作面冒落带高度约是采高的4倍、裂隙带高度约是采高的16倍,高抽巷合理布置层位约为距煤层顶板42m。

英文摘要：

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 4times of mining height,fractured zone height is about 16 times of mining height,reasonable position of the high level drainage roadway is about 42 m 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.
