摘要: 结合8204工作面地面垂直立孔、“L”型钻孔及顶板抽放巷布置情况,塔山矿在深入分析矿井瓦斯涌出特点的
基础上,实施本煤层钻孔预抽工作面超前卸压带瓦斯技术,一方面补充了8204小煤柱工作面瓦斯治理手段,另一方面为
开拓瓦斯治理新途径奠定了基础。

Abstract: Based on the situation of ground vertical borehole, "L" type drill hole and roof drainage roadway arrangement in 8204
working face, the mine gas emission characteristics was deeply analyzed in Tashan Coal Mine, gas extraction technology was
performed in zone of pressure releasing in advance to pre -drainage by coal seam drilling, which supplemented gas control
measures in 8204 small coal pillar face and also laid a solid foundation for exploring the new ways of gas control.

Key words: pressure relief in advance;coal seam drilling;gas emission
