摘要
本文依据采场支架一围岩共同作用原理,分析了采场矿山压力研究方法、顶底板条件、支件一围岩体系的影响因素及支架选型原则,从先进、安全、经济的角度提出回采工作面液压支架应具有的合理的初撑力和工作阻力。
By the principle of support-adjoining rock effet in a face,this thesis sums up the methods of rock Pressure research,and analyzes the adaptable conditions of adjoining rock、 the factors of effectjng support-adjoining rock system and the axiom of seletting supports.The optilnal beginning work-pre ssure and final work-resistance of support is determined.
