摘　　要：研究了构造控制性裂隙与巷道布置匹配不同对回采巷道的稳定性影响规律,分析了裂隙间距、裂隙倾角及其裂隙方位和巷道轴向夹角因素对巷道围岩收敛变形的影响关系,提出构造控制性贯通裂隙条件下保证巷道稳定及其维护的裂隙-巷道轴线匹配布置原则。The stability effective law of the mining roadway because of different coupling between controlled tectonic fissures and roadway layout is studied.And the effects of fissure′s spacing,fissure′s inclination and fissure′s coupling angle with roadway trend on roadway around-rock displacement is mainly studied,the coupling principle between fissure′s trend and roadway layout in order to ensure roadway′s stability and maintenance under rock-mass controlled by tectonics fissures is finally put forward.
