煤矿工作面回采巷道支护设计

Support design of coal mining roadway

针对某矿工作面地质及煤层特点复杂的情况,在详细分析其煤层、地质及水文情况的基础上,结合生产经验和理论分析,提出了该回采巷道支护设计的思路,并着重对"锚杆+锚索+梁+金属网"基础支护方案中的锚索进行加固,为提升该工作面生产的安全性奠定了基础,对提升该工作面的产煤效率具有现实意义。

In view of the complex geological and coal seam characteristics of XX coal mine working face,based on the detailed analysis of its coal seam,geological and hydrological conditions,combined with the production experience and theoretical analysis,this paper puts forward the idea of supporting design of the mining roadway,and focuses on the reinforcement of the anchor cable in the foundation supporting scheme of "bolt + anchor cable + beam + metal mesh",which lays a foundation for improving the safety of the working face production and has practical significance to improve the coal production efficiency of the working face.
