| 摘 要： | 就主采空区地表塌陷对铁路客运专线的危害性按照《建筑物、水体、铁路及主要井巷煤柱留设与压煤开采规程》及相关规范技术要求,对线路与主采空区之间的安全距离进行了量化评价,之后就小窑采空区场地对高等级铁路稳定性运用浅埋采空平衡拱的理论量化评价。以上两种量化评价的结果是可以保障线路与主采空区之间的安全距离,该小窑采空区顶板不受力,顶板地基稳定性差,最后文中对场地地基稳定性差的线路基础提出处理措施与建议。

| Abstract: | We had carried out the quantification appraisement on the safe distance between railway line and chief goal area according to the Mining Regulations of buildings, water body, railway and some chief protecting coal pillar and coal mining as well as some relative thechnical regulations, at the same time, some theoretical quantification appraisement on shallow buried mined-out balance arch had been finished according to the stability of small pit goaf. Both results of the quantification appraisement could ensure the safety distance between railway and chief goaf area. The goaf roof with worse stability is not pressed. Some suggestion had been submitted at the end of the paper to inprove the groundsill stability. |
