液压自移支架参数很多,本讲只介绍与矿压有关的支架吨位(工作阻力)、初撑力和结构高度的确定方法。 一、我国现用的三种支架吨位确定法 我国自力更生研制液压自移支架的实践指出:吨位过小,顶板断裂,下沉量大,台阶下沉,顶板破碎,漏顶、“网 Hydraulic self-moving stent a lot of parameters, this talk only describes the mine pressure and related support tonnage (work resistance), initial strength and structure height determination. First, China’s current three kinds of support tonnage determination method Our self-reliance development of hydraulic self-supporting stent practice points out: the tonnage is too small, the roof fracture, sinking large, sinking, roof crushing, roof leakage, "net
