| 摘 要： | 为了保证9109回风顺槽安全快速过X0陷落柱,保证过陷落柱期间顶板稳定性,七一煤矿通过技术研究,采用导硐分层爆破施工工艺,提出了“撞楔超前支护+注浆锚棚支护”联合加强支护措施。通过实际应用,过陷落柱期间顶板未发生冒落现象,顶板下沉量控制在0.13m以下,取得了显著成效。

| Abstract: | In order to ensure the 9109 return air passing through the x0 collapse column safely and quickly,and ensure the roof stability during the period of passing through the collapse column,Qiyi Coal Mine,through technical research,adopts the layered blasting construction technology of the pilot tunnel,and puts forward the combined support measures of"wedge impact advance support+grouting anchor shed support".Through practical application,no roof caving occurred during the period of collapse column,roof subsidence was controlled below 0.13m,and remarkable results were achieved. |
