缓倾斜厚煤层石门揭煤快速掘进技术

Rapid tunneling technology of rock cross-cut coal uncovering in gently inclined thick seam

煤矿中石门揭煤工作难度较大,处理不当经常会造成瓦斯突出。文中根据缓倾斜厚煤层石门揭煤特点,分析了揭煤中存在的威胁,从瓦斯防突技术和掘进保护技术方面提出了缓倾斜厚煤层石门揭煤快速掘进技术的可行性,为石门揭煤快速掘进提供了新思路。

It is difficult to uncover coal in rock cross-cut in coal mines,and the gas outburst will be caused by improper handling.Based on the characteristics of rock cross-cut coal uncovering in gently inclined thick seam,the threat of coal uncovering was analyzed,and the feasibility of rapid tunneling technology for rock cross-cut coal uncovering in gently inclined thick seam was put forward from two aspects of gas outburst prevention technology and tunneling protection technology,which provides new thought for rapid tunneling of rock cross-cut coal uncovering.
