Zusammenfassung:The invention is featured by drawing coal-gas as energy source with a pipe system in mines in operation and shut-down making full use of the space in the coal mine. This invention is a further development of the safety coal mining method without air ventilation (already applied for a patent). This method, simple and convenient, requires simple equipment, very low operating cost and only a small quantity of electric energy. It can be used in new and old mines operated with the said method. The coal gasification rate is generally higher than 10 m3/t coal.
