Anderson, R C

This document describes the design, manufacture and development of a continuous mining system capable of meeting the following parameters: minimum average extraction rate of 750 tons per shift; operation in seam heights from 6 foot to 9 foot; machine shall be able to continuously advance under supported roof; and machine is automated and remotely controlled so operators remain under supported roof. The distinguishing feature of the Joy Miner/Bolter is its semi-automated remote bolting modules that install resin grouted roof bolts on 4 foot centers simultaneously with the mining cycle. This is a large step toward achieving a completely automated continuous mining cycle. The underground demonstration was conducted at Mine 51, Ellsworth Division of Bethlehem Mines Corporation at Ellsworth, Pennsylvania. During the in-mine test it was never possible to simultaneously install roof bolts while the mining cycle was being performed. Instead, the components were evaluated by performing the mining and bolting operations in sequence.
