【摘要】：利用顾桥矿前期施工2个工作面10口钻井抽采数据,结合矿井地质地层特点与开采工艺,分析、判别影响抽采效果的有利与不利因素,指导、优化后期施工2个工作面5口钻井的结构与布井方式。通过对比分析前、后两期产气情况,表明通过优化的Ⅲ型钻井在合理的布井方式下基本能够适应顾桥地层,抽采半径达到250~460m,取得较好的抽采效果。
[Abstract]:Based on the extraction data of 10 drilling wells in 2 previous working faces of Guqiao Mine, combined with the characteristics of mine geology and strata and mining technology, the paper analyzes the favorable and unfavorable factors that affect the extraction effect, and gives guidance. To optimize the structure and layout of 5 drilling wells in 2 working faces in the later stage of construction. By comparing and analyzing the gas production before and after the last two periods, it is shown that the optimized type 鈪，
