1、 毕业设计说明书毕业设计说明书 题题 目：综采工作面设备选型目：综采工作面设备选型 I 摘摘 要要 本设计主要研究了综采工作面采煤机、液压支架、刮板输送机以及乳化液泵站的 选型设计。综合机械化采煤是指完成落煤、装煤、运煤以及顶板支护等一系列机械化 的总称。本设计中所研究的煤层为采高 2.9 米的中厚煤层，是较为常见的，所以选型 较为容易，采煤机型号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 M

2、G400/930WD 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 II Mechaniz

3、ed mining face equipment selection Summary This design is mainly mechanized mining face shearers, hydraulic support, scraper conveyor, and emulsion pumping station selection design. Mechanized coal mining is completed off the coal, and installed a series of mechanized general term of the coal, coal

4、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 models mainly based on coal seam hardness, thickness, angle select, selection also calculate the main parameters of the shearer cutti

5、ng height, cutting depth, productivity, drawing speed, traction and cutting speed, the installed power. This design selected the MG400/930WD Shearer, the shearer is more common in China. In transport design selected matching with MG400/930WD SGZ880/800 type conveyor and conveyor transmission capacit

6、y and the strength of the scraper chain checking. Selected in the roof support according to the stability of the roof support shield support, the frame type according to the mining height, resistance, etc. to determine this design in the selection of ZZ4000/17/35 type, but also use a more common frame type, but also on the supporting strength checking, determine the total number of face bracket required. Emulsion pump station, this design also specific design calculat
