摘要
分析了梅河二井5103区煤巷多钻孔封闭式预抽瓦斯方法,并通过效果检验及与传统预抽方法比较,有施工时间短、抽放时间短、抽放效果好、施工安全、抽放安全和抽放费用低等诸多好处,且可以在条件类似的矿井中应用,能达到较好的预抽效果。
The paper analyzed gas pre-pumping of several holes enclosure in coal road of the #5103 area Meihe of the No. 2 mine. , through analysis on the application and comparing with the traditional pre-pumping, Testing result shows that the method has many advantages, such as：simple operation, short operating time, gas drainage works pretty good, safe and low cost and so on. The method can apply to the similar mine all can achieve the same higher Pre-pumping yields.
