摘要
本文通过对台头煤矿前湾子坑口矿2S224综采工作面液压支架载荷、超前支护段的单体支柱载荷和煤壁钻孔应力在回采过程中的变化规律观测研究,总结了2#煤层回采期间的矿压显现规律,为现场生产管理提供技术指导。
Through the observation of hydraulic support load,individual hydraulic prop load for advance support and stress of bores coal wall of 2S224 fully mechanized working face,it gets the law of pressure behavior in 2# seam,which are all for providing technical supports for the practical management.
