科兴龙马煤业3208回风顺槽掘进面过空巷的技术措施

Technology Measures of Excavation Face Return Roadway Groove of 3208 Over an Empty Lane of Kexing Longma Coal Mine

以科兴龙马煤业井下3208回风顺槽掘进过程为例,为了保证掘进工作面正常施工进度,从巷道布置及支护方法与通风角度提出相关安全技术措施,确保掘进工作面安全通过此空巷,不仅能降低空巷成本,而且可提高推进速度,为相似条件矿井过空巷操作提供经验。

Taking Longma Coal Mine 3208 branch groove in the tunneling process as an example, in order to ensure the excavation face normal construction progress, from the roadway layout and support method of ventilation and put forward relevant safety technical measures to ensure the safety of the roadway, roadway can not only reduce the cost,improve the speed, this is important for the similar promote the value and operation reference.
