公路桥、铁路桥煤柱开采可行性技术分析

Technical analysis of feasibility of coal pillar mining of highway bridge and railway bridge

矿区铁路桥、公路桥是煤矿企业重要运煤通道,压覆了大量的煤炭资源,为安全回收压资源需对桥梁采取保护性开采措施。文中分析了矿区地质采矿条件、地表移动观测数据及桥梁的抗变形能力,通过对开采方案对比分析,确定了最优开采方案,并提出了安全开采措施。

The railway bridge and highway bridge were important coal transportation channels for coal mining enterprises in the mining area. And A large amount of coal resources had been crushed. It was necessary to take protective mining measures for bridges for safe recovery of pressure resources. In this paper, the geological mining conditions, the surface movement observation data and the anti-deformation ability of the bridge were analyzed in the mining area,the optimal mining plan was determined and the safe mining measures were proposed through the comparative analysis of the mining plan.
