摘要
为实现首阳山煤矿3101工作面安全、高效、低成本通过陷落柱的目的,将选用柔性支护技术对巷道围岩进行支护工作,并针对水害、瓦斯的防治制定了一系列安全措施。结果显示,施工周期总计20 d,过陷落柱期间矿压变化稳定,没有发生片帮、烂网等事故,说明以“金属网+钢丝绳”为主的柔性支护技术具有低成本、高效率的技术特征。
In order to realize the purpose of safety, high efficiency and low cost of 3101 working face in Shouyangshan Coal Mine, flexible support technology will be used to support the surrounding rock of roadway, and a series of safety measures have been formulated for the prevention and control of water damage and gas. The result showed that a total of construction was 20 deys, during the construction period, the change of mine pressure is stable, and there are no accidents such as patch and broken net.It shows that the flexible support technology based on "metal mesh wire rope" has the technical characteristics of low cost and high efficiency.
