Designs for extraction level layouts used in block caving mines may vary in terms of geometrical configuration and dimensions. The design of the extraction level in caving mines is mainly based on maximizing ore recovery at a low cost under safe and stable conditions. In this paper, we analysed the extraction level layouts commonly used as well …

This section is focused on block caving method. Block caving is a technique in which gravity is used in conjunction with internal rock stresses to fracture and break the rock mass into pieces that can be handled by miners. Block refers to the mining layout in which the ore-body is divided into large sections of several thousand square meters.

Parameters influencing full scale sublevel caving …. Sublevel caving (SLC) is a mass mining method based upon the utilisation of gravity flow of blasted ore and caved waste rock [1]. Mechanized sublevel caving longwalling method was used as one of the mining methods in the Lencsehegy II. coal mine in Hungary. The Lencsehegy coalfield ….

1 INTRODUCTION At present, three of the five Codelco-Chile producing mines are underground and use the mining method known as Block Caving: El Teniente, Ro Blanco (Andina) and El Salvador. Fine copper recovered from these operations is today in the order of 570.000 tpy, out of a total of around 1.600.000 tpy produced by Codelco.

High production rates and low operating costs highlight block caving as one of the favorable underground mining methods. However, the uncertainties involved in the material flow make it complicated to optimize the production schedule for such operations. In this paper, a stochastic mixed-integer linear optimization model is proposed in order to …

Abstract: This paper supplements a keynote address prepared for the 2010 Second International Symposium on Block and Sublevel Caving. The author gauges the cave mining industry's position (practice and theory) since the publication of what he considers a seminal paper on 'Cave mining – state of the art' (Laubscher, 1994), hence '16 years after'.
