% of extraction- board & pillar mining- part I

[@nautytom90]

Bhai dout hai, half of gallery width add ya substrate hoga na, ya full??
Kyun aap full gallery width ko use kiye ho

[@MiningTechnicalMT]

Because we need to find % of EXTRACTION.
During development only gallery size coal is extracted.
Half gallery width in bottom and half gallery width on top = full gallery width.
In CTC PILLAR = ACTUAL PILLAR WIDTH + width of gallery

[@MiningTechnicalMT]

If you need to find
Width of CTC PILLAR = you have to add width of gallery to pillar width.
If you need to find width of actual pillar = you need to substract width of gallery from width of pillar CTC

A retreat longwall coal mining system utilises twin accesses on both the intake and return sides of a panel whose face width is 300m. If the access drives are 5m wide and chain pillars are 20m wide between the accesses determine the extraction ratio for the following cases:
a) Panel under development.
b) Panel under production

A board and pillar panel will be developed with square pillars of size 25m and an extraction ratio of 30%. The width of the gallery in m will be ....
