潞安矿区单一厚煤层“U+高抽巷”瓦斯治理竖直层位探讨

Vertical Position Discussion of High-level Drainage Roadway for Methane Control in a U Type Working Face in the Single Thick No.3 Coal Seam in Lu'an Mining Group

随着潞安矿区井回采工作面"U+高抽巷"瓦斯治理模式持续推广应用,高抽巷层位合理布置尤为重要。为此,在常村2103工作面、余吾S2107工作面及司马1207工作面先行先试,根据相关工作面试验情况,分析相关抽采数据及工作面瓦斯治理效果,从竖直层位的影响进行效果考察,比较得出潞安矿区高瓦斯矿井"U+高抽巷"瓦斯治理模式最优竖直层位,为其他高瓦斯矿井高抽巷布置提供借鉴。

With the on - going methane control mode application of ＂U ＋ high - level drainage roadway＂ , there is an increasing need for the reasonable position of high - level drainage roadway for optimal methane control effect. In this study, methane control effect of high - level roadway position was studied based on its application in 2103 Working Face in Changcun,S2107 Working Face in Yuwu and 1207 Working Face in Sima. The optimized vertical position of high - level roadway was got for highly gassy coal mines in Lu an Mining Group by analyzing methane drainage data and methane emission control effect, which can be taken as a reference for other mines employing high - level roadway.
