东庞矿电气化铁路变形监测技术研究

Study on deformation monitoring technology of electrified railway in Dongpang Mine

通过对东庞矿2914工作面电气化铁路下采煤地表变形监测站观测资料的分析和总结,得出了铁路下采煤地表移动和变形参数。根据实际观测的下沉曲线和预计曲线的对比,验证了铁路下采煤所采取的开采方案科学合理,为今后电气化铁路下采煤积累了经验,提供了依据。

By analyzing and summarizing the observed data from the monitoring station of coal mining surface deformation under the electrified railroad at the 2914 working face of Dongpang Mine,the parameters of coal mining surface movement and deformation under the railroad were derived.Based on the comparison of the actual observed subsidence curve and the expected curve,the mining scheme adopted for coal mining under railroad was verified to be scientific and reasonable,which accumulated experience and provided a basis for future mining under electrified railroad.
