| 摘 要： | 某矿3302工作面一侧为采空区,一侧为未采工作面.回采期间,该工作面回采巷道破坏十分严重.以3302工作面为研究对象,通过矿压观测研究了半岛大采高工作面矿压显现规律,掌握了该工作面顶板来压特征、巷道超前支承压力范围及强度、支架活柱下缩规律等,为指导该工作面的后期开采工作提供了详实的实测依据. |
| 关 键 词： | 大采高工作面 矿压观测 矿压显现规律 |

| Abstract: | On the mining face 3302 in some mine,one side is goaf,and the other side is unexploited mining face.During the period of mining,the roadways are damaged seriously.Taking 3302 working face as the research object,through the field measurement method,strata-pressure behavior was observed and studied on peninsular working face with large mining height.The characters of roof weighting,the range and intensity of preacted abutment pressure,and the laws of inner prop retraction were obtained.These results can provide lots of measurement basis for the future mining work. |
| Keywords: | working face with high mining height mine pressure observation laws of strata-pressure behavior |
