摘　　要：针对山东新矿集团某矿Ⅱ4运输上山所面临的深部近距离跨采巷道支护难题,采用数值模拟和现场试验等方法,围绕深部近距离跨采过程中的围岩活动规律和巷道变形特征,研究Ⅱ4042综采工作面开采对Ⅱ4运输上山围岩稳定性的影响,详细研究近距离跨采巷道围岩变形规律,结合Ⅱ4运输上山地质采矿条件,研究提出了Ⅱ4运输上山合理围岩控制技术。Aiming at the support problem of deep close distance overhead mining roadway at Ⅱ 4 uphill transport in a mine of Xinwen Mining Group Company, using numerical simulation and field measurement methods, based on activity laws and deformation characteristics of deep roadway close surrounding rock in the process of overhead mining, the article studied the influence of Ⅱ 1042 fully mechanized coal face mining on stability of Ⅱ 4 rock uphill transport, researched the close overhead mining roadway deformation combined geological and mining conditions of Ⅱ 4 transport uphill, and proposed reasonable control technology forⅡ 4 transport rock uphill.
