A coal mine has a rail capacity constraint of 2.38mtpa. The mine needs to produce one tonne of blended product (1:2) every 12.6 seconds. CHPP capacity only needs to be 320tph at 85% yield. The CHPP could receive a 320t load from CF-B once every three hours, and a load from CF-A once every 1.5 hours.

Underground hard-rock mining accounts for 40 percent of global mining operations but only 12 percent of run-of-mine (ROM) production. 1 Run of mine is ore that is mined and crushed. In this article underground mining refers to underground hard-rock mining; thus, underground soft-rock mining, such as coal, is excluded.
