为了弄清华北地区煤矿底板透水事故机理和防治现状,对华北地区多个矿井进行水文地质资料收集,从矿井富水系数和涌水量等方面研究华北煤矿的水文地质状况,了解华北地区煤矿的防护设备、人员以及防水管理情况,分析2012—2015年华北煤矿发生较大透水事故的机理和主要原因,为华北地区煤矿的防水治水提供资料基础。 In order to understand the mechanism and prevention and cure of pervious flooding in coal mine floor in North China, the hydrogeological data of a number of mines in North China were collected, the hydrogeological conditions of North China coal mines were studied from the aspects of water rich coefficient and water influx, and the protection of coal mines in North China Equipment, personnel and waterproof management of the coal mine in North China. The mechanism and the main causes of the greater water-permeable accident in North China Mine from 2012 to 2015 are analyzed to provide the data foundation for the water and water treatment in coal mines in North China.
