摘要
为解决西直格庄金矿采准巷道围岩变形破坏严重、难支护等问题,采用FLAC^(3D)数值计算软件确定了联合支护技术支护参数的合理性,并进行了工业性试验。现场实践结果表明:采用锚网索联合支护技术方案可有效控制围岩巷道的变形破坏,保证了巷道的长期稳定。
In order to solve the problems such as serious deformation and failure of surrounding rock and difficult support of mining roadway in Xizhigezhuang Gold Mine, the rationality of supporting parameters of combined support technology was determined by FLAC^(3D) numerical calculation software, and industrial tests were carried out.The field practice results show that the technical scheme of combined support with anchor mesh cable can effectively control the deformation and failure of the surrounding rock roadway and ensure the long-term stability of the roadway.
