1、摘要通过对内蒙古上湾煤矿的调查研究,得出该煤矿的煤层厚度大,一次性采全高相对困难,若采用普通综和机械化开采开发会产生工作面采出率低,含矸率大等问题。为了解决上湾煤矿的生产要求。确定以综放开采的形式进行开发。本次设计的研究方法是首先通过煤矿的年产量确定日产量再通过采放比确定采煤机的生产能力,然后选择与之能够配套的相关设备。通过整理机械设备为选择相关电气设备做好基础。通过对这些设备有序的选择和整理来满足整个综合机械化开采的要求。通过选择各种机械设备及电气设备来满足适应上湾煤矿生产需求。保证煤层的稳定开采。同时掌握所选机电设备的选型原则、计算方法,以及各设备的性能特点。关键字:综放工作面;机械设备选
