Abstract
The requirements of the establishments of the Ukrainian Refractories and Ore Association for bucket-wheel excavators can be satisfied with the ER-315 and ER-630 types. The first of these include the excavators ERG-120 12/0.8 and SRs-240 9.5/0.5. In the design specifications for bucket-wheel excavators for operations at the face, account must be taken of the special features of the technological process, the principal one being that the lumps of the excavated material are of the required size and that the machine remains stable and efficient without loss of extracted material when working seam sections with a dip of up to 8°.
