Sublevel Caving Underground Mining Cost

2020-8-20  Methods have been tried, but today, sublevel caving is the only one used.One of the key factors affecting the mining costs in sublevel caving is the amount of development work for production.This cost is very dependent of the sublevel height.As the sublevel height increases, the amount of development work necessary for production decreases.

Sub Level Caving - PHDessay

2017-3-3  The wall caving is induced by mining the ore in controlled sequence, usually from hanging wall to footwall and from top to bottom. Sublevel caving is often used in conjunction with surface mining. Sublevel caving extracts the ore via sublevels, which are developed in

Underground Caving Mining Methods Australia

2019-12-16  Block Caving. Due to the huge volume of production, block caving is such a open pit mining but underground! In this method, ore is removed by the mining, or undercutting, of a thin horizontal layer at the mining level. Gravity and internal stresses within the rock mass are two of main functions in block caving. Sublevel caving (SLC)

Abstract - USGS

Underground mining models are also established using a base case. In this instance, the basic assumption for the underground mining models is an adit entry to the mine. To allow for the variability in access depth common to underground mining, depth adjustment factors are pro­vided at the beginning of the underground section.
