石门揭煤最容易发生煤与瓦斯突出,而且突出的强度较大,因此,在石门揭开有突出危险的煤层之前,必须对煤层采取防突措施,消除了局部范围内煤层的突出危险,确保了掘进期间的安全,为类似条件石门揭煤期间防防突治理提供了借鉴。鸡西矿业集团平岗矿14#煤层具备发生煤与瓦斯突出条件,为保证揭煤过程的安全,通过技术创新,严格执行“四位一体”防突综合措施,加强顶板控制,安全通过强突煤层,为巷道揭煤后安全掘进提供了借鉴。
Therefore, it is necessary to take measures to prevent outbursts in the coal seam before removing the coal seam with prominent danger from the stone door, and to eliminate the prominent danger of the coal seam in the local area and ensure the safety of coal seam During the excavation of the safety of similar conditions Shimen exposed during the prevention and treatment of conflict prevention provided a reference. In order to ensure the safety of the coal uncovering process, the 14 # seam of Jixi Mining Group, Pinggang Mine, has the conditions of coal and gas outburst. Through technological innovation, the “Four in One” and “Outburst Prevention” measures should be strictly enforced to enhance the roof control and safety through strong Outburst coal seam provides a reference for the safe excavation after roadway uncovering coal.
