液压支架的设计选型是煤矿工作面综采设备选型和配套的核心,利用数值模拟分析方法和浅埋深顶板结构理论计算方法确定了液压支架的支护强度,根据煤层厚度和煤层结构确定了支架的架型、支架高度和底板等必要技术参数,对实际生产具有一定的指导意义。 The design and selection of hydraulic supports is the core of selection and matching of fully mechanized mining equipment in coal mining face. The support strength of hydraulic supports is determined by numerical simulation and theoretical calculation of shallow deep roof structure. According to the thickness of coal seam and the structure of coal seam, The frame of the stent, stent height and floor and other necessary technical parameters, the actual production has a certain significance.
