摘要
本文根据有关工作面矿压研究成果,建立了采场支护系统的顶板结构摸型。通过力学计算及分析,得出了支架总工作阻力作用点移向工作面煤壁可以改善支架对破碎顶板的控制。提出了一些改善支撑式液压支架控制破碎顶板的具体途径,通过分析得出了合理的支护参数。
According to the studied results of underground pressure of face, the model of roof structure in the system of stope support is established, it is obtained that the bearing points of otal working resistance moving to the face line ahead may improve the controlling of btoken roof with chock-type Powered support, some methods are put forward and the rational support parameters are given finally.
