【摘要】:利用顧橋礦前期施工2個(gè)工作面10口鉆井抽采數(shù)據(jù),結(jié)合礦井地質(zhì)地層特點(diǎn)與開(kāi)采工藝,分析、判別影響抽采效果的有利與不利因素,指導(dǎo)、優(yōu)化后期施工2個(gè)工作面5口鉆井的結(jié)構(gòu)與布井方式。通過(guò)對(duì)比分析前、后兩期產(chǎn)氣情況,表明通過(guò)優(yōu)化的Ⅲ型鉆井在合理的布井方式下基本能夠適應(yīng)顧橋地層,抽采半徑達(dá)到250~460m,取得較好的抽采效果。
[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,
