Abstract: Mechanized mining face in abnormal area with high water level is seriously threatened by water hazards during mining. In order to ensure mining safely, the effective comprehensive water prevention and control technology must be taken to solve the problems in the process of production. The comprehensive water prevention and control technology for these faces is studied before mining. By constructing dedicated sluicing roadway, DC electrical exploration, drilling for detection and drainage, and targeted water prevention and control technology in mining, the mining face with large water in such special conditions is mined safely. The practice shows that the comprehensive water prevention and control technology has certain reference meaning to mining safely for other mechanized mining faces with similar hydrogeological conditions.
