摘要
淮北许疃矿7229工作面为大采高工作面,采高最高达到6.3 m。为摸清大采高工作面的矿压显现规律,对7229工作面进行了系统的矿压观测,指导了7229工作面安全生产,而且对本矿以后的大采高工作面实现安全高效开采具有重要的现实意义。
7229 working face of Xutuan coal mine of Huaibei Mining Group is the working face with large cut-ting height,the mining height is up to 6.3m.In order to find out the mineral pressure regularity , the systemat-ic mine pressure observation system was carried out , it is not only give effective guidance to safety production of the working face, but also has important practical significance for the safe and efficient exploitation of future working face with large cutting height in Xutuan coal mine.
