Feasibility Studies of a Bidirectional Auger System and a Machine Mining Plan. Volume II. Machine Mining Plan.

摘要

This report documents work performed under a Bureau of Mines contract to study and develop two innovative mining systems:An underground auger capable of augering into the right and left ribs without repositioning the machine,and a conventional mining system employing recently developed innovative machinery. The report is in two volumes to document the studies separately. Volume II describes the studies of mining equipment performance and mining plans developed to determine a conventional mining plan offering improved productivity.
