摘要
通过对9101高档普采工作面的矿压观测分析研究,准确了解工作面上覆岩层的运动变化规律及其变化参数,弄清矿压显现程度及其对工作面生产的影响情况,为下喇叭煤矿9号煤开采积累经验创造了条件。
Movement law of top rock were obtained though analysis and study of observation on underground pressure at 9101 high -grade conventional mining work face, which provided foundfation for safe and high effect minning in Xialaba coal mine.
