ABSTRACT
In this way several complexes of blocks are prepared and coal is burned in them one by one. To do this the lighting devices are put into operation by remote-controlled method, and stream of air is delivered to fire working place 7. The output gases move through the breakthrough channels 4 to gas pipeline 9 and, using a pumping method, they are delivered to the turbines of power station or heat exchangers. During the coal burning process the temperature in the block in operation reaches 1000-1500°C. At this the caved-in rock of the goaf 8 is heated up to the same temperature and keeps it for a long time. All this time into pipe collector’s input 5 the water (power-carrier) is being delivered and gas of high temperature is obtained at the output and is transported to the power station’s turbines. By regulating the circulating speed of heat-carrier in the collector depending on the required temperature and quantity of steam one can control the process of heat exchange in the power block. The intensity and speed of coal burning
can be influenced by the quantity of input air. Coal burning is carried out without presence of people in mine working places.
