摘要
以寺河矿W2301工作面顺槽掘进为工程背景,采用有限差分软件FLAC,对大采高工作面的多巷连掘进行数值计算,分析不同煤柱下工作面应力分布状态,在此基础上提出合理的护巷煤柱留设尺寸,为后续多巷连掘工作面的巷道布置提供理论依据。
Taking W2301 working face in Sihe mine as engineering background,the stress distributions under different coal pillar are received by using FLAC.Reasonable pillar dimension is received based on large amounts of data numerical analysis.A reference is provided for subsequent face multi-lane layout.
