摘要
在对比分析了底板梳状定向钻孔技术相较于传统条带瓦斯治理方法存在的技术优势和先进性的基础上,利用该项技术及配套装备成功在薛湖煤矿施工了2个深度达到600 m以上且煤段控制长度500 m以上的底板梳状钻孔,并对其抽采数据进行了收集整理和理论计算分析。结果表明,采用底板梳状定向钻孔治理条带瓦斯具有理论和实际可行性,为不具备本煤层瓦斯治理条件的矿区提供了一种条带瓦斯治理新思路和新方法。
Based on the comparative analysis of the technical advantages and advancements of floor comb type directional borehole technique with traditional strip gas control method. Using this technology and supporting equipment, two floor comb type directional boreholes with a depth over 600 m and a control length of 500 m were successfully constructed in Xuehu coal mine, collecting the date of gas drainage and analyzing and calculating the date cheoretically. It turned out that it is theoretically and practically feasible to control strip gas by using floor comb type directional borehole, providing a new idea and method for strip gas control in mining area without gas control conditions of this coal seam.
