摘要
针对西山煤电集团公司杜儿坪矿南大巷破碎变形严重难以返修的150 m巷道,应用网壳结构锚喷浇注支护新技术,有效地控制了巷道围岩的严重变形,实现了软岩动压巷道长久稳定支护,取得了明显的经济技术效益和社会效益。
In connection with 150 m tunnel which serious breakup and deformation, repairs with difficulty in south roadway of Duerping coal mine of Xishan coal electricity group company, applies the new technology of reticulated shell structure and bolting and shotcreting pouring support, has controlled effectively serious distortion of the tunnel wall rock, realizes long- time stable supports of the soft rock dynamic pressure tunnel, obtains obvious economical technical benefits and social efficiency.
