Productivity of a Continuous Mining System for Block Caving Mines
Block caving mining is one of the most cost-effective underground mining methods. The method has particular relevance in the Chilean mining industry, where approximately this research the maximization of NPV and the optimization of the mine life in block caving. Both of these goals have required the integration of geomechanical aspects of the ore LONG TERM PLANNING OF BLOCK CAVING OPERATIONS USING

Open pit or block caving? A numerical ranking method for selection
Overview of block caving mining Block caving is a high-tonnage underground bulk mining method generally applied to large homogeneous ore deposits. Ideally, the ore to be caved should be structurally weak, and the waste overburden should be weak enough to collapse over the ore as the ore is extracted (Figure 1).

An overview of block caving operation and available
Block caving is a mining method that can achieve high extraction rates and low operational costs. Ore grade can be low to moderate and the deposits can be fairly steep (Pourrahimian and AskariThe block caving mining method has become increasingly popular in the last two decades. Meanwhile, Indonesia has several potential ore bodies which have not yet determined suitable mining methods. The references to block caving mining projects worldwide and the potency of metal deposits in Indonesia were reviewed to determine the requirements Energies Free Full-Text Block Caving Mining Method:

GEOMECHANICAL EVALUATION OF A MECHANICAL UNDERCUTTING SYSTEM IN BLOCK
Nowadays, Block Caving is the underground mining method with the highest productivity in the world. Many of the components of block caving have changed in the last few years, This thesis proposes to use a mechanical system to perform the undercutting, similar to the longwall method used in coal mines. In order to evaluate the technicalapplication of real time microseismic monitoring system in underground mine operation to support a safety production.
