The delimiting method of the stope width under high-pressure aquifer

    摘要
  • 摘要: 根据岩体水力学理论及突水系数理论推导了确定工作面斜长的公式,并用此法确定了东庞矿910 3工作面的斜长为70m。实践证明此方法具有可靠性和可操作性。

     

    Abstract: Two equations are deducted according to the rock hydraulic theory and water inrush coefficient theory.The width of 9103 stope in Dongpang Coal Mine is decided according to the two equations.The practice shows that the method is reliable and easy to operate.
