Development regularity and height of overburden water-fractured zone in 3101 working face of Yechuan Mining Industry

为有效分析确定野川煤业3101工作面覆岩导水裂隙带的发育规律及高度,采用数值模拟与物理相似模拟相结合的研究手段,结合3101工作面的具体情况,分别建立数值模拟和物理相似模拟模型,对采动裂隙带的发育规律和渗流规律进行模拟分析。结果表明,3101工作面上覆岩层导水裂隙带最大发育高度约为130 m,冒落带约为25 m,裂隙带约为107 m,弯曲下沉带约为30 m。

In order to effectively analyze the development law and height of the overburden water-fractured fissure zone of the 3101 working face, the numerical simulation and physical similarity simulation model were established by combining the numerical simulation with the physical similarity simulation method and the specific conditions of the 3101 working face. The development law and seepage law of mining fissure zone were simulated. The results showed that the maximum development height of the water-cracking zone of the overlying strata in the 3101 working face was about 130 m, the caving zone was about 25 m, the fracture zone about 107 m, and the curved sinking zone about 30 m.
