临海高盐富水砂层S曲线斜坡道冻结法施工

Construction of S-Curve Ramp with Freezing Method for High Salt and Watery Sand Layer by the Sea

莱州市瑞海矿业有限公司瑞海金矿斜坡道冲积层段地质条件复杂,采用冻结法施工;采用较为先进合理的施工机械化作业线与新的施工工艺及专业工种,滚班作业。实际施工中,扣除影响因素,直线段月成巷达45 m,曲线段达35 m,在直线、曲线多次转换和复杂的地质条件情况下,进度较快,对类似工程有较好的借鉴作用。

The geological conditions of ramp alluvium in Ruihai Gold Mine of Laizhou Ruihai Mining Company Limited were complicated,so freezing method was adopted for construction.With the professional types of work,the engineering project was continuous completed by shifts by means of more advanced and reasonable construction mechanized operation line and new construction technology.In the actual construction,after deducting the influencing factors,the monthly tunneling of straight section roadway was 45 m,and that of curve section roadway was 35 m.In the condition of multiple conversion of straight section and curve section and complicated geological conditions,the progress of the engineering construction was fast,which would have a good reference for similar projects.
