seismicity, and these determine the support conditions for different sizes of developments. Generally most geological structures at 1 Shaft are considered as potentially hazardous in respect of rock falls, particularly that mining takes place at a relatively shallow to intermediate depth, and that access developments remain

Furthermore, it is difficult to get even contact and bearing between the many faces. (In fact, too many cuts may actually prevent maximum support). READ PART 1 of Timber Support in Underground Mining It is important to remember that only three pieces of the set are used to describe a square-set or express its efficiency or economy.

The overall stiffness can be determined numerically, but it is a lengthy procedure. If a fracture zone develops ahead of mining as it may in intermediate depth mining, yield pillars may be designed to have a width less than that of the fracture zone. The pillars are pre-failed and cannot burst, but can offer good local support to the roof .

Earthquake - Earthquake - Shallow, intermediate, and deep foci: Most parts of the world experience at least occasional shallow earthquakes—those that originate within 60 km (40 miles) of the Earth’s outer surface. In fact, the great majority of earthquake foci are shallow. It should be noted, however, that the geographic distribution of smaller earthquakes is less completely determined ...

Cycle mining - A system of mining in more than one working place at a time, that is, a miner takes a lift from the face and moves to another face while permanent roof support is established in the previous working face. D. Demonstrated reserves – A collective term for the sum of coal in both measured and indicated resources and reserves.
