摘要
为了探索特厚煤层综放开采过程中工作面的矿压显现程度、矿压显现特点及其规律,摸清基本顶来压步距及其规律,观测支架运行状态,研究支架与围岩关系,对同忻矿首采工作面石炭系3~5号层北一盘区8101面进行了详细的矿压观测,总结了特厚煤层放顶煤工作面矿压显现规律,为综放工作面安全回采提供了理论与技术支持。
In order to explore the law of rock pressure ,the characteristics of ground behavior ,clear the law and weighting step distance of the main roof ,observe the running status of hydraulic support ,and study the relation between support and surround‐ing rock ,this paper have observed the rock pressure of carboniferous No .8101 working face which is the first working face of Tongxin Mine in detail .Summarizing the law of rock pressure of ultra thick seam fully mechanized caving face .It also supplies the theory and technology support of fully mechanized caving face mining safely .
