How to deal with the coal resources produced in the process of coal field fire fighting?

1. Coal cinder recovery: The coal cinder produced in the process of coal fire extinguishing can be physically and chemically treated to extract available coal resources. These resources can be used in thermal power generation, industrial production and other fields.

2. Recovery of coalbed methane: In the process of coal fire fighting, a large amount of coalbed methane may be produced in the coal seam. These gases can be recovered and used in power generation, heating and other fields.

3. Coal treatment: Coal resources generated during fire fighting can be treated with coal and converted into liquid or gas fuel. These fuels can be used in transportation, chemical industry and other fields.

4. Utilization of coal gangue: A large amount of coal gangue may be left after fire fighting in coalfield. These gangue can be physically and chemically treated to extract available coal resources.
