Abstract
"From the results obtained after a year and a half of operation using the long face system of conveyor mining in our thin seam of coal, four decided advantages over the old system of room and pillar work with wide rooms have been proven: 1. Operations are concentrated in small sections, thereby permitting larger tonnages to be loaded. 2. One hundred per cent extraction of the vein is obtained (with the exception of main slope pillars) which prolongs the life of the mine. 3. The ventilation of this gaseous vein is simplified. 4. Production costs are reduced"--page 15.
