And then the results of theoretical calculation and numerical simulation are that the range of caving zone and fracture zone are respectively 6.2-8.3m and 23.0-28.2m, which are consistent with the results of experimental test in working environment. With the aid of application of theoretical calculation and numerical simulation, it leaded to that the gas extraction flow rate is more than 1m³/min in the fracture zone. Thus, based on our method the precise heights of "three zones" are very helpful for improving the gas drainage quantity of high-level bore and high-level gas suction roadway in Pinggang coal mine. The methods and results of our research will be significant for guiding the practical production in the future., authors=ZHU Hongqing, ZHANG Minbo, SHEN Jian, WANG Feiran, HU Ruili, authorsList=ZHU

articleAbstract=为准确判定“三带”对于提高平岗煤矿高位孔和高抽巷的瓦斯抽放量,采用理论计算、数值模拟、现场试验方法,研究了平岗煤矿1202工作面采空区上覆岩层“三带”的判定问题。理论计算与数值模拟得到冒落带高度范围为6.2～8.3m,裂隙带高度范围为23.0～28.2m;现场测试结果与理论计算值基本一致。在裂隙带中实施瓦斯抽放,瓦斯流量可达1m³/min以上。本文所提出的方法为高位孔终孔位置和高抽巷层位的确定提供了重要的参考依据,能够有效降低工作面瓦斯超限事故的发生。,
