自然灾害是煤矿安全的大敌,而要提高矿井抗灾防灾能力,首先要解决矿井“一通三防”硬件设施的建设。1987年投产的燕子山矿,16年来,在防灾抗灾方面做了许多尝试和探索,也积累了许多有益的经验。 燕子山矿,井田面积49.998平方公里,东西走向长9公里,南北长6.3公里,地跨大同市南郊、左云县两地,共有可采煤层13层,煤层总厚度13.98米。由于赋存条件不同,矿井目前只开采4＃、8＃、12-1＃、12-2＃、14-2＃和14-3＃煤层,且4＃、8＃、12-2＃和12-2＃煤层已基本采完,现主采的是14-2＃煤层,采煤方法为综合机械化开采。
Natural disasters are the enemy of coal mine safety. To improve mine disaster prevention and disaster prevention capability, we must first solve the mine’s “one through, three-prevention” hardware facilities. Yanzishan Mine, put into operation in 1987, has made many attempts and explorations in disaster prevention and mitigation in the past 16 years and accumulated many beneficial experiences. Yanzishan mine, mine area of 49.998 square kilometers, east-west long 9 km, 6.3 km long from north to south, across the southern suburbs of Datong, Zuoyun two places, a total of 13 coal seam mining seam, the total thickness of 13.98 meters. Due to the different conditions of occurrence, the coal mines are currently only mining 4 #, 8 #, 12-1 #, 12-2 #, 14-2 # and 14-3 # coal seams, and 4 #, 8 #, 12-2 # and 12 -2 # seam has been basically finished mining, the main mining is 14-2 # seam, mining method for the comprehensive mechanized mining.
