Considering the relative position of working face and the floor roadway,the stress evolution of surrounding rock masses,rock displacement around floor roadway induced by overhead mining,and the roadway stability at different position are analyzed in detail by numerical simulation. The results show that the abutment pressure distribution on coal pillar is the direct reflection of abutment stress induced by mining on the interfaces of coal seam and immediate roof. The rock displacement around roadway under nearby overhead mining is influenced by the whole displacement induced by mining as well as abutment pressure on the coal pillar. The floor roadway should be located out of the abutment stress zone when protection coal pillar is retained,or the working face should be pushed away for enough distance under overhead mining. The study result is proved by a case analyzed.

针对近距离跨采时,工作面与底板岩巷的不同空间位置关系,采用数值力学分析,详细地分析了工作面开采引起的围岩应力演化过程及特点、近距离跨采引起底板岩巷围岩位移的特点以及巷道位置对其围岩稳定性的影响。研究结果表明,煤柱上支承压力分布是开采影响岩层相互作用的结果,是开采引起集中应力在煤层与直接顶界面上的直接反映。近距离跨采巷道围岩位移受开采引起的整体位移场影响较大,而不单纯决定于煤柱侧支承压力的作用。留设保护煤柱时,底板岩巷应位于集中应力区的外侧或跨采时工作面应推过足够距离,使巷道靠近采空区应力恢复区的下方。最后通过实例给予了分析。
