摘要
以梁家煤矿4600工作面下顺槽沿空掘巷为基础,对巷道围岩的支护方式及支护参数进行了合理的优化分析与研究。并通过FLAC3D模拟软件,对2种支护方式的支护效果进行了模拟对比。对巷道围岩的支护方式及参数进行了优化分析。
According to Liangjia mine 4600 work face,the roadway support method and support parameters were reasonable optimization analysis and research based on the down crossheading gob-sid entry driving. By FLAC3D analysis software ,supporting effect of two support on the way were compared. Optimization analyse of the methods and supporting structure with the roadway .
