System for supplying underground working with two=component mine rock hardening facility

摘要

The system has a container (1) with special fittings for handling the rock-hardening materials. It has a positively controlled withdrawal device (10-16) for the pressing component as well as a replenishment device for the repeated circulation between user and supplier. The containers for both components are of identical construction, although they are marked externally for the components. The inside space of the containers for the isocyanate rock-hardening components is divided into two chambers lying one behind the other and with approx. the same capacity.
