3317工作面采空积水超前探放技术的研究与应用

Research and Application of Advanced Exploration and Drainage Technology for Gob Water in the 3317 Working Face

针对郭庄煤矿采空区积水水害,根据3317工作面的水文地质概况,按照采空区位置,进行探放水钻探施工,设计探放水方案,顺利解决采空区积水问题,并对探放水效果进行验证。结果表明:在采用超前探放水技术后,水压从0.09 MPa降到0.02 MPa,约下降77%,共计排放水总量为6539 m^(3),有效缓解了采空区的积水情况,治理效果显著,为工作面的安全回采奠定基础。

Aiming at the water disaster of goaf in Guozhuang Coal Mine,according to the hydrogeological situation of 3317 working face,according to the location of goaf,the water exploration and drainage drilling construction is carried out,the water exploration and drainage scheme is designed,the water accumulation problem in goaf is successfully solved,and the water exploration and drainage effect is verified.The results show that:after adopting the advanced water detection and drainage technology,the water pressure is reduced from 0.09 MPa to 0.02 MPa,about 77%,and the total amount of discharged water is 6539 m^(3),which effectively alleviates the water accumulation in the goaf,and the treatment effect is remarkable,laying the foundation for the safe mining of the working face.
