2、的选择主要根据煤层硬度、厚度、倾角等因素来选取，选型后还要计算采煤机的主要参数，采高、截深、生产力、牵引速度、牵引力、截割速度、装机功率。本设计中选用了 MG400/930WD 采煤机，本采煤机在我国使用较为普遍。在运输方面本设计选用了跟 MG400/930WD 配套的 SGZ880/800 型输送机，并对输送机的输送能力以及刮板链的强度进行了验算。在顶板支护中根据顶板的稳定性选用了支撑掩护式支架，架型需要根据采高、工作阻力等来确定，本设计中选用了 ZZ4000/17/35型，也是使用较为普遍的一种架型，还对支护强度进行了验算，确定了工作面所需支架的总数量。本设计还对乳化液泵站进行了具体的设计
3、计算，根据所选液压支架的主要技术参数计算了泵站的压力，并对乳化液泵站各设备进行了选型。最后本设计还对整体进行了配套验算，并做出了三机配套图。关键词：关键词： 综采综采 工作面工作面 选型选型 设备设备内蒙古科技大学毕业设计任务书（毕业论文）IIMechanized mining face equipment selectionSummaryThis design is mainly mechanized mining face shearers, hydraulic support, scraper conveyor, and emulsion pumping station selectio
4、n design. Mechanized coal mining is completed off the coal, and installed a series of mechanized general term of the coal, coal and roof support. Mining height of 2.9 m thick coal seam, the coal seams studied in this design is more common, so the selection is relatively easy, Shearer choice of model
5、s mainly based on coal seam hardness, thickness, angle select, selection also calculate the main parameters of the shearer cutting height, cutting depth, productivity, drawing speed, traction and cutting speed, the installed power.This design selected the MG400/930WD Shearer, the shearer is more com
