一、前言单一不稳定突出危险煤层的防突问题,是目前我国防突技术研究的难点之一。如何根据具体的煤层瓦斯地质条件寻找相应的有效防突措施,形成具有单一不稳定煤层特点的防突技术,具有重要意义。英岗岭矿区是我国煤矿中突出最严重的矿区之一,开采单一不稳定突出危险煤层,防突技术难度大。过去虽然试用过多种防突措施,但突出并未得到较好地控制。为了改善英岗岭矿务局的防突面貌,江西省煤研所和英岗岭矿务局合作研究了
I. Introduction Single Instability Highlighting the Outburst Prevention of Dangerous Coal Seam is one of the difficulties in the research of outburst prevention technology in our country. How to find the corresponding effective outburst prevention measures according to the specific geological conditions of coal seam gas and to form the outburst prevention technology with the characteristics of a single unstable coal seam is of great significance. Yinggangling Mine is one of the most prominent coal mines in China. It is very difficult to highlight the dangerous coal seams with a single instability of mining. In the past, many measures against outbreaks were tried out, but the outstanding ones were not well controlled. In order to improve the anti-glaring face of Yinggangling Mining Bureau, Coal Research Institute of Jiangxi Province and Yinggangling Mining Bureau collaborated to study
