阳泉矿务局四矿,于1986年9月安装并使用了从波兰引进的CMC-1型环境安全监测设备。通过一年多的运行,在安全生产中起到了重要作用,现简介如下。 一、矿井概况 阳泉矿务局四矿为年产250万吨的大型矿井。现在主采煤层为沁水煤田12~#、15~#两层,层间距为40～50米。12~#煤厚1.5～1.8米,瓦斯赋存量较大,邻近的不可采煤层也富含瓦斯,一般相对瓦斯涌出量为20米~3/吨,
Yangquan Mining Bureau, four mines, in September 1986 to install and use from the introduction of Poland’s CMC-1-type environmental safety monitoring equipment. After more than one year’s operation, it has played an important role in safety production. The brief introduction is as follows. First, the mine profile Fourth Mine, Yangquan Mining Bureau is an annual output of 2.5 million tons of large-scale mines. Now the main coal seam Qinshui coalfield 12 ~ #, 15 ~ # two layers, the spacing of 40 to 50 meters. 12 ~ # coal thickness 1.5 ~ 1.8 meters, large gas content, adjacent to the coal can not be reclaimed is also rich in gas, the relative gas emission is generally 20 meters to 3 tons,
