中国煤矿突水灾害特点与发生条件

The characteristic and generant condition of coal mine water-bursting calamity in China

中国煤矿突水灾害十分严重。基本特点是:分布广,发生频次高;突水水源以岩溶水为主;突水通道主要是导水断裂和岩溶陷落柱。突水事故发生原因,除自然地质条件外,还与矿区水文地质勘探程度不高、开采方法不当(甚至是违规开采)以及监测防治不力等人为因素密切相关。

The coal mine water-bursting is very severe in China. The important characters, such as the broad distribution with height frequencyt, groundwater is the mainly source, water-bursting＇s channels mainly include the producing fracture and karstic falling column. There are many man-made factors relate to it such as the lacking of geohydrological reconnaissance, the unbefitting mining systems （even get out of line）, the supervisal and preventions besides the natural geology conditions.
