长榆河煤矿回采巷道支护设计研究

摘要

为了保障长榆河煤矿15102工作面的安全高效开采，采用数值模拟的方法分析了巷道围岩应力及塑性区分布规律，并提出了相应合理的支护方案，确保了15102工作面平巷的稳定性，为长榆河煤矿的生产积累了丰富的经验，也为其它地区类似条件下的巷道支护提供了工程示范。%In order to realize the safe and high efficient production in 15102 Working Face of Changyuhe Coal Mine, the numerical sim-ulation method was used to analyse the stress and plastic zone distribution law of mining gateway and put forward the reasonable and corresponding supporting scheme which ensure the stability of the mining gateway in 15102 Working Face.The research result accumu-late rich production experience and provides demonstration for the similar conditons.
