摘　　要：通过分析夹矸厚度和位置对巷道围岩稳定性的影响,得到夹矸层厚度存在临界值,巷道围岩稳定性随夹矸厚度呈先减小后增大的趋势,当夹矸层位于巷道围岩上部时,围岩稳定性相对较好。在此基础上提出了合理的围岩控制技术和支护参数,确保了工作面的安全高效生产。By analyzing the influence of thickness and position of parting towards the surrounding stability of roadway, the critical value of parting were obtained which indicates that surrounding stability of roadway decreases and then increases with the growth of parting thickness ,when the dirt band is located upper the tunnel, the stability of surrounding rock of tunnel shows well enough. Based on this, an acceptable surrounding rock control technology and supporting parameter are raised, which ensures the safety and high efficiency of working face.
