采用预掘高抽巷进行采前、采中瓦斯抽采技术,解决高瓦斯工作面瓦斯超限引起的系列灾害事故,是淮南矿区成功瓦斯治理的根本措施之一.本文以丁集煤矿1341(1)工作面为工程背景,针对顶板高抽巷布置层位、支护方案进行FLAC3D数值模拟分析,得到锚网索支护、矩形断面开掘的距11-2煤顶板法线距30m的1341(1)高抽巷,能快速成巷、围岩稳定性好,抽采效果显著,成功的工程实践表明:模拟为同类条件下高抽巷快速成巷、高效抽采提供了可靠预判.
採用預掘高抽巷進行採前、採中瓦斯抽採技術,解決高瓦斯工作麵瓦斯超限引起的繫列災害事故,是淮南礦區成功瓦斯治理的根本措施之一.本文以丁集煤礦1341(1)工作麵為工程揹景,針對頂闆高抽巷佈置層位、支護方案進行FLAC3D數值模擬分析,得到錨網索支護、矩形斷麵開掘的距11-2煤頂闆法線距30m的1341(1)高抽巷,能快速成巷、圍巖穩定性好,抽採效果顯著,成功的工程實踐錶明:模擬為同類條件下高抽巷快速成巷、高效抽採提供瞭可靠預判.
