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。

Abstract: In order to study the high level suction roadway reasonable position, according to the mining conditions and the overburden characteristics of 13-1 coal seam in Huainan mining area Liu Zhuang coal mine, by using these methods of theoretical calculation and similar simulation experiment and engineering practice, research and analysis of the high level suction roadway reasonable position and extraction effect. The results showed that 13-1 coal seam working face caving zone height is about 4 times of the mining height, fractured zone height is about 16 times of the mining height, the high level suction roadway reasonable position is about from the coal seam roof 42m. By using the similar material simulation test results to determine the high level suction roadway position is more reasonable.
