摘　　要：以某煤矿的煤层工作面为研究对象,首先,测定出底板比压,确保支架对底板的比压值应低于底板容许比压,其次,确定了老顶的级别与直接顶的类别,根据经验参考筛选液压支架架型,并计算出了液压支架所需的主要参数,最终完成了该煤层工作面综采机械化液压支架的选型。Taking the coal seam face of a coal mine as the research object, first of all, the specific pressure of the bottom plate is measured to ensure that the specific pressure of the support to the bottom plate should be lower than the allowable specific pressure of the bottom plate. Secondly, the grade of the old top and the category of the direct top are determined, the hydraulic support frame type is selected according to the experience reference, and the main parameters needed for the hydraulic support are calculated, and the selection of the mechanized hydraulic support for fully mechanized mining in the coal seam face is finally completed.
