Plough system for underground mining

摘要

The invention relates to a plough system, consisting of a shiftable conveyor (11) along which a plough train is guided on the working-face side along a plough guide (23, 24). The plough train has ploughs (2), coupled via a push-pull linkage (3), at the working face (10). The feed system for the plough train consists of a cylinder chain with a group of thrust-piston mechanisms connected one behind the other in the longitudinal direction and connected to one another in an articulated manner. The cylinder chain is connected to the plough train via a runner. In this arrangement, the runner has a runner plate (26) or the like which runs below the conveying strand of the conveyor, preferably between the conveying strand and the return strand. <IMAGE>
