| 摘 要： | 分析了华丰煤矿第三系砾岩的水文地质特征 ,认为传统的观点 ,即认为砾岩出水是因为砾岩与四层煤的间距小 ,四层煤采后的冒裂带高度达到砾岩 ,具有片面性。该矿的砾岩出水除与砾岩的富水性有关外 ,还与矿井的冲击地压有密切关系。第三系底部的红层强度非常低 ,不具隔水性能或隔水性能不好 ,也是砾岩出水的原因之一。

| Abstract: | Analysis on the hydrogeological conditions of Tertiary conglomerate in Huafeng Coal Mine,author suggests that the traditional ideas are lopsided.The water inrush from conglomerate in the coal mine relatives to the water rich property of conglomerate and the pressure bump.The strength of red beds in the floor of Tertiary is too low to have water resisting property,which is one of causes of the water inrush from conglomerate. |
