CLIMATE REGULATIONS AND AIR CONDITIONING IN DEEP GERMAN COAL MINES.

Author(s) : MUCKE G. H.

Summary

WITH A MEAN DEPTH OF 900 M AND A MAXIMUM DEPTH OF MORE THAN 1,400 M, ROCK TEMPERATURES OF 313 TO 333 K (40 TO 60 DEG C) OCCUR IN MINE. THE AIR IN A LONGWALL WORKINGCAN PICK UP 1 TO 2 MW OF HEAT AND MORE. VENTILATION MEASURES ARE NOT ABLE TO ENSURE PERMISSIBLE ENVIRONMENTAL CONDITIONS. FOR A LONGWALL WORKING WITH A SALEABLE OUTPUT OF 1,500 T/D AND FOR AN IN-SEAM DRIVAGE WITH A HEADING MACHINE, THE CLIMATE CONDITIONS AT A ROCK TEMPERATURE OF 323 K (50 DEG C) ARE CALCULATED WITH AND WITHOUT AIR CONDITIONING. IT IS SHOWN THAT FOR COAL GETTING AND DRIVAGE A REFRIGERATOR RATING OF 1,300 KILOW, RESPECTIVELY 470 KILOW, IS REQUIRED IN ORDERNOT TO EXCEED AN EFFECTIVE TEMPERATURE OF 302 K (29 DEG C).
