摘要
安阳矿务局大众煤矿为煤与瓦斯突出矿井,在煤巷掘进过程中采用"四位一体"防突措施,由于效检指标超标率高,导致煤巷掘进速度十分缓慢。论文通过对大众煤矿水力挤出现场实验找到了一套适合大众煤矿的注水参数,使得该矿煤巷掘进速度有了明显提高,实现了安全快速掘进。
Dazhong Mine of Anyang Coal Mining Administration is a coal mine with coal and gas outburst. There are ＂Four Position and One Integration＂ anti outburst measures applied to seam gateway heading. Due to the efficiency check index too higher to the standard rate, it caused the seam gateway driving speed too slow. With the site experiment on gas hydraulic releasing in Dazhong Mine, the paper found a set of the water injection parameters suitable for Dazhong Mine, which could obviously improve the seam gateway driving speed in the mine and could have a safety and rapid driving in the seam gateway.
