摘要
针对目前受底板承压水威胁的工作面注浆效果评价以及工作面回采过程中异常区裂隙动态发育等情况的动态监测问题,采用电法智能监测技术,在唐家会煤矿 61304 工作面底板低阻异常区开展注浆效果监测试验以及对回采过程中煤层底板进行实时监测,通过监测岩层电阻率变化情况,成功捕捉到了注浆浆液动态扩散趋势和采动裂隙动态发育过程,及时预警了导水通道的动态发育情况.研究表明:电法智能监测技术能清晰监测导水通道动态发育过程,能分辨是否导通含水层,是带压开采工作面底板突水监测的新技术,为底板承压工作面的开采提供技术指导,保障煤矿安全生产.
Abstract
In view of the problems in grouting effect evaluation in working face threatened by floor confined water and dynamic monitoring of the dynamic development in abnormal areas in working face during mining,the electrical intelligent monitoring technology was adopted to carry out grouting effect monitoring test and coal seam floor real-time monitoring during mining in the low resistance abnormal area of 61304 working face in Tangjiahui Coal Mine.By monitoring the change of rock resistivity,the dynamic diffusion trend of grouting fluid and the dynamic development process of mining-induced fissure were successfully captured,and the dynamic development of water-conducting channel was timely warned.The research shows that,the technology can clearly monitor the dynamic development of the water-conducting channel and distinguish whether the channel is connected to the aquifer.It is a new technology for monitoring the floor water inrush for working face mining under safe waterpressure of aquifer,providing technical guidance for mining with floor confined water and ensuring the safety of coal mine production.
