摘要
山西沁源留神裕煤矿采区巷道施工中遇到地质陷落柱,影响采区巷道正常施工,通过对地质陷落柱的工程地质研究分析,采用管缝锚杆作超前支护、减轻围岩震动、短掘短支等施工方法,成功地通过了地质陷落柱。
A geological sink hole was met in the mining gateway construction of Liushenyu Mine,Qinyuan,Shanxi Province and was affected to the normal construction of the mining gateway.With the engineering geological study and analysis on the geological sink hole,the pilot support with the spilt bolts,the vibration reduction to surrounding rocks,short distance excavation with on time support and other construction method was applied to successfully pass through the geological sink hole.
