摘　　要：为研究综采工作面覆岩导水裂隙带发育高度,以霄云煤矿1314工作面为研究背景,采用工程地质调查、理论分析、数值模拟、现场实测等手段进行了研究,研究结果表明:1314工作面上覆岩层为“中硬”岩层,理论分析、数值模拟、现场实测获得的导水裂隙带发育高度较一致,为保证较高安全系数,取实测最大值作为最终结果,即导水裂隙带发育高度为39.5 m,裂采比为11.29,以裂采比11.29作为基础参数指导地质概况类似的工作面导水裂隙带高度预测分析是较合适的。In order to study the development height of the water-conducting fissure zone in comprehensive working face, this paper takes the 1314 working face of Xiaoyun coal mine as the research background, and uses engineering geological investigation, theoretical calculation, numerical simulation, field measurement to carry out the research.The results show that the overlying strata of 1314 working face is “Medium Hard” strata and the height of the water-conducting fissure zone, which is derived from theoretical calculation, numerical simulation and field measurement, is more consistent. In order to ensure a high safety factor, the measured maximum value is taken as the final result, the development height of the water-conducting fissure zone is 39.5 m and the fissure extraction ratio is 11.29.It is more suitable to take the fissure extraction ratio of 11.29 as the basic parameter to guide the prediction analysis of the water-conducting fissure zone height of the working face with similar geological.
