Device for cutting minerals in place in the rock formation

摘要

In a known combination of an endless cutter chain with high-pressure water nozzles, the nozzles are arranged in a stationary position on both sides of the cutter chain in the cutting frame. They are intended to release or loosen the mineral, while the cutters mainly effect the removal of the released mineral. According to the invention, the high-pressure water nozzles are integrated in the cutters (23). The cutter holders (14) are fluidically connected by connecting tubes (29). The high-pressure water is fed to the system of cutter holders (14)/connecting tubes (29) via a gate body (41) movable in the longitudinal direction of the cutting frame (5) and having a rotary transmission lead-through (50) and coupling tube. Connecting tubes (29) and coupling tube circulate in a space (39) which is defined by a cover plate (20), the cutter chain (7) and the supporting longitudinal rib (9) of the cutting frame (5). <IMAGE>
