顿涅茨克煤炭研究所哥尔洛夫斯克分所为开采厚度0.55～0.8米煤层研制了浅截式《—2》型采煤机,骑在С—64或С—48型输送机槽帮上并具有小的刚性底托架(4900mm)、重量4746kg、高度305mm。采煤机装有一个直径550或630mm水平轴螺旋滚筒工作机构。滚筒置于机体的端部。预定按煤层厚度(在550～840mm范围内)平滑地调节滚筒高度。技术特征列于表中。
The Donetsk Coal Research Institute, Golovski Branch, developed shallow-cut “-2” shearer for the mining of 0.55-0.8 m thick coal seam, riding on the С-64 or С-48 conveyor slot And with a small rigid bottom bracket (4900mm), weight 4746kg, height 305mm. Shearer equipped with a diameter of 550 or 630mm horizontal axis spiral drum working mechanism. Roller placed at the end of the body. The thickness of the drum is scheduled to be adjusted smoothly to the seam thickness (in the range of 550 to 840 mm). Technical characteristics are listed in the table.
