Study on the Flameproof High Power Emergency Power Supply System for Auxiliary Fan in the Coal Mine

2011 International Conference on Control, Automation and Systems Engineering (CASE), 2011
A variety of measures are taken to improve the reliability of power and wind supply of auxiliary fan for heading face in the coal mine, however, almost of all coals adopt the manner of laying cable for power supply at present, when mechanical damages occurred, yet it would cause power and wind cut. Therefore the paper develops a backup flameproof 660V-

Abandoned coal mine tunnels: Future heating/power supply centers

Mining Science and Technology (China), 2011
Abstract We have studied three plans for re-use of the abandoned mine roadway tunnels as an energy center. These are the thermostat plan, the thermal accumulator plan, and the CAES plan. Calculations show that the thermostat plan can provide over 15,000 m2 of building air-conditioning/heating load for each kilometer of roadway, but electric power is ...
