Bidirectional Cutting Cycle SRB parameter “Cycle” must be set to “BIDI” to use SRB in a bidirectional cutting cycle.
Parameter “Cycle”
When using the bidirectional cutting cycle, the shearer cuts the entire top and bottom coal, full depth, as it travels in both directions. In both directions, the shields are advanced and the conveyor is pushed. When the shearer reaches the endgate, a double cut is required to keep the gates even with the rest of the face.
Bidirectional Cutting Cycle Beginning at Headgate The bidirectional cutting cycle can begin with the shearer at either the head or tail end of the face. The picture below shows the shearer at the HG ready to start. The shearer is already in the coal; the coal face has a snake at the headgate. The shields and conveyor are completely straight and completely pushed. Bidirectional Cutting Cycle – Initial Position
