高水位异常区综采工作面综合防治水技术

Research and application of comprehensive water prevention and control technology for mechanized mining face in abnormal area with high water level

高水位水文异常区综采工作面开采时受水害威胁较大,为了保证安全开采,必须采取有效的综合防治水措施。通过在东欢坨井田2286工作面回采前对该类工作面进行综合防治水技术研究,利用施工专用泄水巷道、直流电法勘探、打钻探放以及回采期间应用针对性的防治水技术,确保了这种特殊条件下大水工作面的安全回采。实践证明,该系列综合防治水技术对其他类似水文地质条件下综采工作面的安全开采具有一定的借鉴意义。

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.
