摘要
根据新集二矿210108工作面工程实际,采用FLAC软件分析了顶板岩性及厚度对采煤面位置两侧煤体应力及位移分布影响,在此基础上得出巨厚砂岩顶板采煤面两侧煤体应力位移分布特点,为工作面附近巷道合理布置提供依据。
Under the new set of Mine 210108 face engineering, analysis of the roof lithology and thick ness of the stress and displacement distribution of coal mining face position on both sides with FLAC software, based on the analysis of thick sandstone roof coal mining face on both sides should be char acteristic of displacement force, as the work surface near the tunnel arrangement provides the basis.
