Abstract

There is provided a continuous mining system comprising at least one chassis, boom arrangement for supporting a continuous miner cutting head, roadheader turntable assembly and, optionally, drilling machine. The latter three items are adapted so that each of them can be removably mounted on any one of the at least one chassis. This enables a continuous mining operation to be carried out without the need to remove the whole of the mining machine if hard rock is encountered.
