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。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.

关 键 词：工作面斜长 抗拉强度 隔水层厚度 临界突水系数
