Combined mining machine equipped with linear motors for parting, loading and conveying material occurring in seams in underground longwall mining

摘要

Combined mining machine without central drive units for parting, loading and conveying material occurring in seams, consisting of a winning and conveying device which are equipped with a linear-motor system in such a way that various advantages can be obtained, such as, for example, the length of the mining machine and the winning front is increased, the power is initiated in a distributed manner over the entire length of the mining machine in each housing at the level of the requisite pulling force, different speeds can be set between winning and conveying device, and greater degrees of freedom in the configuration of return stations and transfer points are achieved by a smaller spatial requirement and a light weight of the mining machine.
