平顶山煤田两翼矿区断层突水危险性分类研究

 断层是造成煤层底板突水的重要原因之一。该文分析了中平能化两翼矿区历次断层突水特征，结果表明，断层突水量大，突水水源大都为寒武系灰岩水，断层突水类型呈现多样性。矿区各主要影响断层突水量计算结果显示，断层突水量与断层突水通道面积、断层带孔隙率和含水层水压值等参数均呈现出线性正相关关系。提出选用断层类别、突水量、是否切割寒武系灰岩含水层、含水层水压值等水文地质特征作为判别因子，将断层突水危险性分为四类，并对中平能化两翼矿区12条主要影响断层进行突水危险性分类，其中判别为一类危险的断层有4条，二类危险的有3条。最后提出断层突水防治措施，为现场防治水提供理论参考。

Study on Classification of Water Inrush Dangers from Faults of Bilateral Mining Areas in Pingdingshan coalfleld

The paper analyzed the features of several fault water inrushes occurred in the bilateral mining areas of China Pingmei Shenma Energy Chemical Group and studied the relationship between each factor of affected to the mine fault water inrush quantity and the fault water inrush quantity.The fault type,water inrush quantity,the aquifer of the Cambrian limestone,water pressure value of aquifer and other hydrogeology features were provided and applied as the distinguishing divisors.The water inrush risks of the fault could be divided in to four types.There were 12 main influence faults in the bilateral mining areas of China Pingmei Shenma Energy Chemical Group classified according to the water inrush risks.Among them,there were four faults distinguished as a first grade risk and there were three second risk faults.Finally,the prevention and control measures of the fault water inrush were provided and could be the theoretical references to the site water prevention and control.
