Underground Mine
CHP Plants
Solar Power Plants

Underground mine consists of complex network of roads and longwall panels.
Shearer cuts the coal as it advances along the coal panel's face. The coal drops onto a conveyor belt called a pan line.
As the coal is cut, the machine moves forward and leaves the goaf collapsing behind the shields.
The coal is moved along the pan line to the stage loader which is a chain conveyor that transports coal to a main belt conveyor.
The coal is transported along the main belt conveyor to the production hoist that transports the coal to the ROM(Run of Mine) stock pile or coal silo within the surface facilities area.
ROM(Run of Mine) stock pile or coal silo is a one of the surface level facilities which store the unprocessed coal before it is sent to the preparation plant.
ROM coal will then be loaded into conveyor system and directed to the Coal Handing and Production Plant(CHHP) where the coal is processed.
At the clean coal silos,the coal is discharged into the truck and ready for transport.
The clean coal is transported to the railroad loadout facility where the coal is dicharged directly to the freight train.

General Process
Power Generation Process
Steam Generation Process
Coal Combustion Process

1-2 The coal from stock yard is conveyed to the coal bunker.

3 The coal from the bunker is sent to coal pulverizer, which crushes the coal into fine powder and send it to the furnace of the boiler.

4 The fine powder burns inside the boiler furnace and generates heat, it heats up the water and generates steam, which flows into the turbine.

5 Driven by incoming steam, the turbine rotates at a high speed, causing the generator to start producing electric current.

6-7 Electrical power from the generator passes through the transformer which adjust the voltage so that it corresponds to the grid voltage.

8 Electricity is then transmitted through the transmission line.

9-11 Some steam which passes through the turbine will flow to the condenser, the condensate will be brought back to the boiler for recycling.

6 Steam extracted / exhaust steam from the turbine supply heat to local industrial plants and/or district heating.

7 Steam extracted from turbine provides energy to cooling station to produce chilled water, for cooling local community / business district.

4 The output of coal combustion includes heat which heats up the water to generate steam for power generation, as well as flue gas.

5-8 Flue gas will pass through flue gas treatment system (DeNOx + Bag filter + FGD), complies with the air pollutant emission standard,then emit to the air through the stack (chimney).
