| 摘 要： | 为了研究放煤工艺对浅埋深综放工作面矿压显现规律的影响,将酸刺沟6上105-2综放工作面在回采过程中不放煤时与放煤时的矿压显现进行对比,分别从周期来压步距、初撑力、末阻力、支架前后柱受力等方面分析了2个不同期间的矿压显现特征,得出了6上105-2浅埋深综放面不放煤与放煤期间矿压显现的区别,掌握了放煤工艺对浅埋深综放工作面的矿压显现规律的影响。

| Abstract: | In order to research the influence of top-coal caving technique on underground pressure behavior in shallow buried full-mechanized caving mining face,underground pressure behaviors including periodical pressure pace,setting load,cycle-end resistance,front and back prop load were compared at the time of top-coal caving and non-caving.Influence rule of top-coal caving technique on shallow buried full-mechanized caving mining face was obtained. |
