ABSTRACT:
Spaced apart single entries are driven into a mineral deposit to be developed by means of a short wall mining machine. A specially designed concrete-receiving slip-form located in the center of the entry is pulled along by a battery of roof supports which are advanced in line behind the mining machine. Quick setting concrete pumped into the anchored slip-form sets up into a wall isolating the two sides of the entry. The slip-form is then released for each successive mining run.
