深部纵跨轨道大巷加固方案设计的数值模拟研究
Numerical Simulation Research on the Reinforcement Scheme Design in the Deep Longitudinal Span Main Track Roadway
深部纵跨巷道由于地压和经受跨采工作面变化支承压力的叠加影响，巷道难于维护。针对姚桥矿7253工作面纵跨-650m轨道大巷地质和生产条件，提出了轨道大巷的两种基本加固方案，同时对这两种加固方案进行了数值模拟的分析。结果表明：在巷道的应力和位移方面，加固方案2略优于加固方案1。
ue to the changes of geopressure and abutment pressure influence on trans-mining face, it's difficult to maintain in deep longitudinal spanning roadway. According to the geological and production conditions for the 7253 Face in the Yaoqiao Coal Mine, spanning -650m main track roadway, the two basic reinforcement scheme of the main track roadway was proposed, and they were analyzed by numerical simulation software. The research results show that the reinforcement scheme 2 slightly better than reinforcement plan 1 in terms of stress and displacement of roadway.
