摘要
针对晋华宫矿河北12-2#层307盘区2714巷地质结构复杂,采用传统的探放水技术方案存在着探测效率低、探测成本高缺陷的情况,提出了一种新的井下巷道探放水的技术方案,根据实际应用表明,该探放水技术方案探测精度高,探测成本低,能够将方案设计时间降低70%以上,钻井井孔的数量降低50%以上,一次钻进合格率提高了61%。
In view of the hebei jinhuagong coal mine 12-2#layer 307 panel 2714 lane,complex geological structure,adopts the traditional drain technology solutions exist defects detection,low efficiency,high cost,this paper proposes a new underground roadway drain technology solutions,according to the practical application shows that the detection precision is high,the solution to drain detection of low cost,can reduce design time by more than 70%,the number of drilling hole to reduce more than 50%,a drilling rate increased by 61%.
