摘要: 针对高等级公路压煤严重,煤炭资源回收率低的问题,结合高等级公路自身的特点及路基沉降要求,分析开采对高等级公路的影响,探讨路基允许移动与变形范围。结合现场实际条件,以某矿区一高等级公路为例,通过充分的理论计算,对高等级公路保护煤柱进行合理留设,达到尽可能多的回收煤炭资源,又对该高等级公路影响控制在保护等级以内的目的,取得了良好的社会经济效益。

Abstract: Aiming at lots of coal resources under high-grade highway and low recovery rate,the impact of mining on high-grade highway was analyzed,and the allowed movement and deformation range of subgrade was discussed with the characteristics of high-grade highway and the settlement requirements of subgrade.With the actual field conditions,and taking a high-grade highway in a mining area as for example,the protective coal pillars of high-grade highway were remained reasonably through full theoretical calculation,to achieve the recovery of coal resource as much as possible,and control the influence of high-grade highway within the level of protection,with good social and economic benefits achieved.
