铁路下采煤是“三下”采煤的重点研究问题之一,郭二庄矿针对开采铁路下22208工作面的煤层而引起地表沉陷,从而是否影响行车安全,对地表变形量进行了长期不间断监测,并将所得数据进行总结、处理,根据结果决定对部分路段沉陷进行治理,从而判断在铁路下郭二庄矿段采煤是否安全有效。 Under the railway, coal mining is one of the key research issues of “three times” coal mining. The Guo Erzhuang Mine caused surface subsidence for the mining of coal seam under the 22208 face under the railway, so as to affect traffic safety and carry out the deformation of the ground surface Long-term uninterrupted monitoring, and the data to summarize, deal with, according to the results decided to manage the subsidence of some sections to determine whether the coal mining Guozhuang Zhuang section of the railway is safe and effective.
