保护煤柱开采期间矿区铁路维护设计模式

Railway Maintenance Design Mode in Mining Protective Coal Pillar

建立了一种在保护煤柱开采期间矿区铁路维护设计模式,通过提出"移动变形曲线"图示法,将开采沉陷动态预计结果转化为铁路维护的时间、范围及工作量大小,并以梧桐庄矿铁路下采煤实践为例介绍了本模式的应用。

This paper set up a railway maintenance mode during mining protective coal pillar.It transferred dynamic prediction results of mining subsidence into railway maintenance time,range and workload by put forward ＂movement deformation curve＂ method.This mode was applied in mining under railway in Wutongzhuang Colliery.
