摘　　要：为改变己15-12010工作面回风巷与其上方高位巷掘进相互影响、顶板极其破碎、支护困难的现状,采用数值分析方法对高位巷与回风巷围岩应力变化规律进行了深入细致地研究.结果表明:回风巷与高位巷水平距离为10 m时,两巷围岩应力相互叠加严重,导致回风巷右帮长期处于高应力作用下,致使其右帮及邻近右帮顶板破碎,支护困难;当水平距离达15 m以上后,两巷围岩应力相互影响较小,顶板完整性变好,巷道掘进速度得以大幅提高.During the course of tunneling, return airway of Ji15 - 12010 working face and upper high location roadway was influenced each other, the roof uncovered was most cracked, and the supporting work was very difficult. Therefore, this paper studied the change laws of surrounding rock stress of high location roadway and return airway in depth. Research results show that surrounding rock stress of high location roadway and return airway are superposed each other when horizontal range between them is 10 m, the right working slope of re- turn airway is affected by high stress frequently, surrounding rock stress of the two roadways are influenced lightly each other when horizontal range between them is 15 m, the roof of return airway becomes intact, and tunneling speed has been greatly increased.
