为了掌握煤层开采导水裂隙带发育规律，以曹家滩煤矿122109工作面为研究对象，采用数值模拟、现场实测等手段相结合的方式对导水裂隙带发育规律进行研究。结果表明：在采动影响下覆岩裂隙的发育扩展受工作面采动影响显著，裂隙带范围在纵向不断攀升，覆岩导水裂隙带呈现两端高中部低的“马鞍”形裂隙发育特征，采动裂隙发育连续，裂隙连通性强，呈现裂隙面棱角剧烈，裂隙宽大的形态特征。实测导水裂隙带发育高度与模拟结果基本一致，最大发育高度为213 m，裂采比为20.32。研究结果对于类似地层条件下矿井涌水的防治和安全高效回采具有指导意义。
Abstract：In order to master the development law of water conducting fracture zones in coal seam mining in the western region, taking the 122109 working face of Caojiatan Coal Mine as the research object. A combination of numerical simulation and on-site measurement methods are used to study the development law of the water conducting fracture zone. The results show that under the influence of mining, the development and expansion of the overlying rock fractures are significantly affected by the mining of the working face. The range of the fracture zone continues to climb longitudinally, and the overlying rock water conducting fracture zone presents a "saddle" shaped fracture development feature with high, medium, and low ends. The development of mining induced fractures is continuous, the connectivity of fractures is strong, and the fracture surface has sharp edges and wide width. The measured development height of the water conducting fracture zone is basically consistent with the simulation results, with a maximum development height of 213 m and a fracture mining ratio of 20.32.The research results have guiding significance for the prevention and control of mine water inflow and safe and efficient mining under similar stratum conditions.
