通过实验室围岩物理力学基本参数测试、现场地应力测试、数值模拟和现场工业性实验等方法，对采动影响下的专用行人大巷的围岩应力、位移演化规律进行了研究。研究结果表明，行人大巷加强支护能有效控制巷道受1202，1206工作面回采而产生的围岩变形；在行人大巷与1203工作面之间设置卸压巷，能有效转移因工作面回采而产生的行人大巷周围围岩应力集中区；卸压巷与1203工作面之间留设55 m的保安煤柱宽度，使行人大巷围岩变形增加量控制在10％之内，并较1206工作面多采出近0.23 Mt煤炭资源，保证了行人大巷的安全稳定，实现了较佳经济效益。

Surrounding rock stress and displacement variation rule of dedicated pedestrian roadway influenced by mining were re -searched by mechanics test , on-the-spot observation , numerical simulation.Results showed that strengthening supporting in the roadway could effectively control surrounding rock deformation influenced by 1202 and 1206 mining face , pressure-relief roadway between pe-destrian roadway and 1203 mining face could transfer stress concentration zone of pedestrian roadway .55m-width protective coal-pillar between pressure-relief roadway and 1203 mining face made deformation increment be less than 10%.This made 1203 mining face more mined 0.23 Mt coal than 1206 mining face , kept pedestrian roadway stable and obtained better economic profit .
