Summary:
The Ulan West underground mines the lower 3 metres of the Ulan seam for thermal coal.
The Ulan Seam generally dips uniformly towards the north-east at between one and two degrees, and the seam thickness averages 5 to 7 metres throughout the Ulan Mine Complex. It consists of ten separate plies, which are consolidated into four working sections within the open cut. The working sections are separated by thin claystone horizons.
Summary:
Ulan West uses standard longwall mining methods to mine the lower 3m of the Ulan seam, known as the D Working Section (DWS), for thermal coal. Longwall 01 was 250m wide , LW2 was 303m wide, the remaining blocks are 400m wide. Access to the mine is via the 6 portals located in the Ulan West Boxcut.

Summary:
ROM coal is delivered to the HUB Stockpile via conveyors from Ulan West underground mine.
There is one dedicated reclaim valve for each underground mine and a shared reclaim valve. The reclaim valves deliver coal to the sizing station where it is crushed. The sizing station can send 50mm top size coal to the ROM stockpile, 50mm top size coal to the product stockpiles or 125mm top size coal to the CHPP. From the ROM stockpile there are three reclaim valves that send the coal into a surge bin with two feeders sending coal to the product stockpile. Underground coal can be delivered via the existing open cut conveyor system through a dump hopper surge bin with sizing and trash screen, bypassing the CHPP, to the product coal stockpile at 2000 tonnes per hour.
The CHPP has a flexible raw coal receivals system which allows either individual, or any combination of, direct plant feed, raw coal stockpiling or reclamation from the stockpile by a bucket wheel reclaimer. A co ........
