摘　　要：在对矿井底板突水评价方法对比分析的基础上,以平煤十矿为例,利用五图双系数法对二1煤层底板寒灰水发生突水的危险性进行了预测评估。通过分析隔水层与水压的关系,计算了带压系数和突水系数;利用Surfer绘图软件,绘制了底板水压、水头分布、突水系数的等值线图和突水危险性分区图。该方法比突水系数法更为全面;与脆弱性指数法相比,不需要太多的相关资料。Based on the comparative analysis of mine water inrush evaluation methods, including the water burst coefficient method, the five figures and double coefficient method and the vulnerability index method, using the five figures and double coefficients method, the risk of the cambrian limestone water inrush on 21 coal floor were forecasted and assessed of the No.10 coal mine of Pingmei. By analyzing the relationship between the impermeable layer and the water pressure, the pressure coefficient and water inrush coefficient were got. Then contour maps of hydraulic pressure on coal floor, thickness of effective water-resisting layer, water inrush coefficient and the partition map of water inrush risk were draw by using Surfer software.
