Beschreibung
Zusammenfassung:	The invention provides a coal, gas and heat coordinated co-production system which comprises a coal gas production unit, a coal water terrestrial heat lifting unit and a gas heat utilization unit. By means of hydraulic coal breaking and gas lift reverse circulation coal pumping, drilling fluid recycling is achieved, the production cost is reduced, meanwhile, terrestrial heat resources, coal bed gas resources and coal can be effectively and synchronously recycled, and the coal, gas and heat coordinated co-production efficiency is improved. The method solves the related technical barriers of high investment cost of single targeted development of conventional coal series associated resources, high technical difficulty of collaborative development, prominent space-time replacement contradiction between gas extraction and coal mining and the like, combines natural characteristics of coal gas heat resources, and designs, develops and configures system equipment through an innovative mining technical mode.
