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 the thickness and location of the gangue on the stability of the surrounding rock, the critical thickness of the gangue is obtained. The stability of the rock surrounding the rock first decreases and then increases with the thickness of the gangue. When the gangue is located in the roadway Surrounding rock stability is relatively good when the upper part of the rock. On this basis, a reasonable surrounding rock control technology and supporting parameters are proposed to ensure the safe and efficient production of the working face.
