摘要
为进一步解放煤炭资源储量,腾晖煤业探索在邻近小煤窑采空积水区布置回采工作面。针对厚煤层探测容易出现的钻探盲区问题,利用钻孔窥视技术准确了解钻孔轨迹,指导钻孔进行“立体压茬式”布孔。在超前探测过程中探索形成“长探+短探+班自探”的综合探测模式,通过合理布设探放水钻孔,成功疏放小煤窑采空积水40500m^3,消除了水害威胁。
In order to further liberate coal reserves, Tenghui Coal Industry has explored the layout of mining face in the goaf water area adjacent to small coal kilns. Aiming at the problem of drilling blind area in thick coal seam exploration, the drilling trajectory is accurately understood by using borehole peep technology, and the drilling hole is guided to carry out “three-dimensional stubble-pressing” drilling. In the process of advanced detection, a comprehensive detection mode of “long exploration + short exploration + self-exploration”was explored. Through reasonable arrangement of water exploration and drainage boreholes, 40500m^3 of goaf water in small coal kilns was successfully drained, thus eliminating the threat of water hazards.
