一、薄煤层采煤机的特点根据我国煤层厚度的划分,小于1.3米属于薄煤层,小于0.8米属于极薄煤层。在0.8米以下的极薄煤层和0.8米以上的薄煤层中实现一般机械化和综合机械化采煤,要比中厚煤层难度大得多。设计薄煤层采煤机有以下几个特点。1.滚筒采煤机在薄煤层中使用往往存在着功率不足的缺点。曾想选用功率较大的电动机,但受到煤层高度的限制,使采煤机骑溜布置困难很大。如果采取机身“爬地”的
First, the characteristics of thin seam shearer According to the thickness of coal seams in our country, less than 1.3 meters belong to the thin seam, less than 0.8 meters belong to the thin seam. It is much harder to achieve general mechanization and mechanized coal mining in very thin coal seams below 0.8 meters and thin coal seams above 0.8 meters. Design of thin seam shearer has the following characteristics. 1. The drum shearer often has the disadvantage of insufficient power when used in thin coal seams. Had wanted to use a larger power motor, but by the height of the coal seam limit, so that shearer ride layout difficult. If you take the fuselage “climbing”
