大多数采煤机都装备螺旋滚筒式(以下简称滚筒—译者)工作机构。中厚煤层滚筒采煤机的广泛应用是由这些工作机构的优点,尤其是其装煤能力高和调高简单的优点所决定的。在开采薄煤层时,滚筒采煤机因其滚筒直径小及装煤能力不足使用上受到限制。 Most shearers are equipped with spiral drum (hereinafter referred to as drum - translator) work organization. The widespread use of medium-thickness coal seam drum shearers is governed by the advantages of these mechanisms, especially their high coal handling capacity and ease of adjustment. In the exploitation of thin coal seam, the drum shearer is limited in its use due to its small drum diameter and insufficient coal loading capacity.
