摘要
采用分段注水法对余吾矿S5203工作面开采后顶板导水裂隙带发育高度进行探测,并详细阐述了分段注水探测原理、探测方案以及探测程序。并将探测结果与地面采用的高密度法探测结果进行比对。结果表明,采用分段注水法探测出的导水裂隙带高度具有较高的可信度,可以指导后续的顶板防治水、开采设计等工作。
The development height of roof water-conducting fracture zone after mining in S5203 working face of Yuwu Mine is detected by subsection water injection method,and the detection principle,detection scheme and detection procedure of subsection water injection are e-laborated in detail.The detection results are compared with those of the high density method used on the ground.The results show that the height of water-conducting fracture zone detected by subsection injection method has high reliability,which can guide the follow-up work of roof water control and mining design.
