安阳矿务局是一个地方煤矿,于1963年建立,目前年产170多万吨。这个矿6对矿井中有5对属高沼气矿井,其中3对突出矿井。根据实验,6对矿井均有煤尘爆炸危险,尤以瓦斯危害最大。龙山、铜冶、王家岭三个矿井建矿以来共突出100余次,最大突出强度为902吨,涌出瓦斯量为15万米~3。 遵照煤 Anyang Mining Bureau is a local coal mine, established in 1963, with an annual output of more than 1.7 million tons. There are 5 pairs of high-biogas mines in 6 of these mines, of which 3 are prominent mines. According to the experiment, 6 pairs of coal mines have the danger of coal dust explosion, especially the most harmful gas. Since the construction of three mines, namely Longshan, Tongye and Wangjialing, they have been outstanding for more than 100 times with the maximum outstanding intensity of 902 tons and the amount of discharged gas of 150,000 m 3.
