摘要
在考虑顶板条件进行理论计算的基础上,使用新设备——双端堵水器进行现场实测,利用井下仰上孔分段注水测漏技术方法,更加精确地研究了A煤矿 9+10#煤垮落带和导水裂隙带高度发育规律,均达到了较好的效果,为工作面布置与防治水工作提供了重要的参考依据,保证了矿井安全高效生产.
Abstract
On the basis of theoretical calculation considering roof conditions,a new equipment—double-end water-stopped device was used for field measurement,and the height development law of 9+10#coal seam caving zone and water flowing fracture zone in A Coal Mine was studied more accurately by using the underground upward hole subsection water injection leak detection technology.The results indicate that good results were achieved,providing important reference basis for the layout of the working face and water prevention work,ensuring safe and efficient production of the mine.
