Properly applied, block-caving is a low-cost, productive mass mining method. However, the amenability of a rock mass to caving is not always predictable. Also, the comprehensive development that is required results in a long lead-time before the mine starts producing the delay in earnings can have a negative influence on the financial

Feb 28, 2018These deposits usually occur beneath barriers like a rock layer, forests, or oceans, which makes accessing them difficult. Depending on how these ores are extracted, mining methods can be categorized as 'surface' or 'underground' types. In surface mining, the rock barrier on top of the deposit is removed to access the ore.

Sublevel caving is an underground mining method in which ore is blasted from the sublevel drifts using explosive charges in a ring (fan) pattern, while the surrounding rock mass in the hanging wall is being spontaneously caved by the influence of gravity.Blasted ore is loaded from the sublevel drifts, and during this process, gravity the flow of broken rock is formed.

LONGWALL MINING Overview. In the method of secondary extraction known as longwall mining a relatively long mining face (typically in the range 100 to 300m but may be longer) is created by driving a roadway at right angles between two roadways that form the sides of the longwall block, with one rib of this new roadway forming the longwall face.
