郭二庄矿铁路下开采及铁路修复技术实践

On the practice of coal mining under railroad and railroad rehabilitation in Guo'erzhuang

从地表移动的基本原理出发,根据现场地表和铁路变形观测,研究铁路下采煤的地表和铁路变形破坏规律,制定了地表铁路修复方案,为铁路下采煤矿井提供了技术和支持。

Starting from the fundamentals of ground surface movement and also on the basis of observations of on-the-site ground surface movement and railroad deformation, a study is carried out on coal mining under railroad and the regularities of disruption to the railroad and the related railroad deformation. This paper also works out railroad rehabilitation schemes thus provides dedicated technology and support to those coal mines whose underground coal mining is to be carried out under railroads on the surface. This paper is hence of appropriate value to special coal mining activities as mentioned.
