... in northern part of India. In most of the cases the orebody occurs as steeply pitching deposit, but often some limbs or lenses of the main orebody occur flatly dipping. This makes them prone to sudden collapse, when extracted using open stoping methods at shallow and moderate depth of cover. It is...

... paper, the variation in fault-slip potential induced by ore extraction in underground mining is examined with a 3D mine-wide model encompassing a steeply dipping tabular orebody at a depth of 1.5km below surface, and in situ stress conditions that are typical of the PreCambrian Shield. The fault is...

... mass. The acquired geometric data of fractures were compared with data acquired by a geologist. Consequently, the fractures were extracted by visible reading of images generated from 3DLS data, and a trace map was generated as geometric data. Strike/dip data of fractures were also acquired. The results...
