MINING METHOD
WCM FACTSHEET
A state of the art modern mine leading the UK coal industry into the mid-21st Century, the mine will utilise modern, well proven mining methods to achieve a
steady-state production of 3.1 million tonnes per annum (Mtpa) Run-of-Mine (ROM).
Run-Out and Pocket Run-Out and Pocket extraction will be the chosen mining method employed by WCM. This is a proven, highly versatile coal mining method that takes advantage of advancements in mining technology to mitigate risks associated with the Cumbrian Coal fields.
g Bolter Miner’s develop the gateroads, for the panel
g A Bolter Miner will then drive a run-out roadway
g A Continuous Miner subsequently cuts chevron cut pockets into the pillars, whilst mobile roof supports support the roof
g Shuttle Cars continuously move coal from the respective miners to the Feeder Breaker
g Once coal has passed through the Feeder Breaker it falls on to the conveyor belt to be taken to surface
3.1 Mt PEAK ANNUAL ROM
PRODUCTION
Advantages of Run-Out and Pocketg Allows greater flexibility and
productivity for the anticipated geological conditions
g Allows for relatively simple scheduling
g Modest Capital expenditure
g Fully mechanised method allows for increased productivity
g Permits for accompanying methods to be utilised if conditions are favourable
g Allows for ground support to be easily installed

Mining Equipment The ‘Run-Out and Pocket’ partial extraction method allows high levels of flexibility of the design stage.
Due to the known faulting within the Cumbrian coalfield the ‘run-out and pocket’ method allows for panels to be designed to fit into the geological conditions, ensuring the most efficient extraction of high quality coal.
The underground layout enables panels to be extracted simultaneously to yield the required run-of-mine output. Typically, each panel is 100 m wide by up to 1.5 km long. These figures will vary across the mine and the method allows the extraction of smaller mining blocks that would otherwise be unsuitable for traditional longwall techniques.
