摘要
严重突出煤层掘进水力掏槽防突措施在国际上是一种防突新技术。在焦作矿区的演马庄矿、九里山矿选择突出危险性最严重的工作面开展试验,取得了良好的效果,在保证安全条件下,大幅度提高了严重突出煤层煤巷掘进速度。在现场试验的基础上,结合相关资料,对水力掏槽措施的消突机理进行了研究。
Grave protrusion coal seam tunnelling hydraulic cutting protrusion -dispelling measures is a new technology in the world. At Yanmazhuang Coal Mine and Jiulishan Coal Mine of Jiaozuo mining area, the face with greatest protrusion danger was chosen to develop the experiment and achieved good results. On condition of safety, the tunnelling speed in grave protrusion coal seam was greatly improved. On the base of spot experiment, combined with relevant materials, the research was made for the protrusion - dispelling mechanism of hydraulic cutting measures.
