摘要
为提高某矿4305综放工作面沿空双巷的稳定性,利用FLAC3D数值模拟软件,对沿空煤柱和巷间煤柱在不同宽度下巷道围岩的塑性破坏和变形规律进行分析,确定合理的煤柱宽度,不仅有效解决了该矿瓦斯超限的问题,还减少了煤炭资源的浪费,并在实际应用中良好的效果。
In order to improve the stability of double gob side entries of the 4305 fully mechanized working face in a coal mine,using numerical simulation software,the damage and deformation law of surrounding rock in different coal pillar width are analyzed,and the reasonable width of coal pillar is determined,which not only effectively solves the problem of the mine gas overrun,also reduces the waste of coal resources with good effect in practical application.
