摘　　要：为保证马兰矿18105工作面大倾角俯采段液压支架的稳定,通过建立大倾角液压支架的力学模型,对保证支架稳定的条件进行分析,结合工作面的具体情况分析保证支架稳定性的具体控制措施及支架的初撑力、工作阻力,并进行矿压监测。结果表明,实施保障支架稳定的控制措施后,保障了回采期间支架的稳定,实现了工作面的安全高效回采。In order to ensure the stability of the hydraulic support of the large inclined angle subduction section of the 18105 working face of Malan Mine,the mechanical model of the large inclined hydraulic support was established to analyze the conditions for ensuring the stability of the support,and the stability of the support is ensured by combining the specific conditions of the working face.Specific control measures and initial support of the bracket,working resistance,and mine pressure monitoring.The results showed that after the implementation of the control measures ensured the stability of the support bracket,the stability of the support during the recovery was guaranteed,and the safe and efficient recovery of the working surface was realized.
