... Abstract In the mines employing the upward horizontal slicing and filling mining method, it is necessary to set up a horizontal separation pillar in the middle transportation section. Too small a separation pillar may cause the roof to fall in the lower stope, damaging the transportation...

.... Expecting 3, rest of the mines is worked through underground methods at shallow 153 m to moderate depth 353 m below the surface. MOIL is producing annually more than 1.2 million tonnes of various grades of manganese ore. All the underground mines are using horizontal cut and fill (HCF) method of stoping...

... is assumed to run parallel to the orebody. Static analysis is first carried out, in which stopes on a given sublevel are sequentially extracted from the center of the orebody in an outward direction. It is shown that when the first stope is extracted, a significant increase in fault-slip potential takes...
