高路堤多桥涵铁路下采煤技术研究

Coal Mining Technology Research under High Embankment Multiple Bridges and Culverts

针对梧桐庄矿运煤专线铁路下压煤量大,沿线高路堤、桥梁、涵洞等附属设施较多,开采保护煤柱对铁路运输安全影响大的问题,分析了具体情况,设计优化了井下工作面的开采方案,并对铁路沿线的各种设施进行科学维护,实现铁路保护煤柱的安全开采。

Based on Wutongzhuang Mine dedicated railway on the large amount, high along the embankment, bridges, culverts and other ancillary facilities, mining protective coal pillar of the problem of the great impact on the safety of railway transportation, the specific situation was analyzed. The design of downhole working face was optimized. Scientific maintenance of various facilities were conducted along the railway, realized the railway protecting the safety of the coal pillar mining.
