1 概况 平顶山矿务局五、六矿原以锅底山断层为分界线。现由于五矿储量有限,为了延长五矿矿井服务年限,缓解矿井接替紧张局面,矿务局于1991年决定,将六矿部分煤量划拨五矿开采。因此,为了开采现五矿己三采区,采区石门必须穿过锅底山正断层,该断层落差110～220m,倾向SW,倾角60°～70°,破碎带范围350m左右,在地质力学上属于压扭性断裂。巷道围岩松软,粘结力差,有膨胀性,岩石层理紊乱,多片理化,石门穿过岩层有细砂岩,页岩、砂质泥岩、泥岩和煤夹层。施工时有水,并具有煤与瓦斯突出危险。
1 Overview Pingdingshan Mining Bureau five or six mine to pot bottom mountain fault line. Now due to the limited reserves of Minmetals, in order to extend the service life of Minmetals mine and relieve the tension of the succession of mines, the Bureau of Mines decided in 1991 to allocate part of its coal mines to Minmetals for exploitation. Therefore, in order to exploit the No.5 mining area and the No.3 mining area, the Shimen in the mining area must pass through the PanDishan normal fault, which has a strike difference of 110 ~ 220m, a tendency of SW, a dip of 60 ° ~70 ° and a fracture zone of about 350m. On the pressure-shear fracture. Roadway surrounding rock soft, poor adhesion, swelling, disorder of the rock layer, multi-piece physical and chemical, Shimen through fine rock, shale, sandy mudstone, mudstone and coal interlayer. There is water during construction, and coal and gas outburst danger.
