Sep 2 2021The following steps should be completed when evaluating a mineral deposit for block caving Apply typical costs and economic cut off values to the resource block model and assess the resulting geometry and block values in terms of block caving size shape and available footprint area and potential economic margins

Block caving refer to a mass mining system where extraction of ore largely depends on action of gravity A thin horizontal layer mining level of ore column is removed using standard mining method This removes vertical support of ore column above then ore caves by gravity f Principle II Broken ore of ore column is removed from mining

Block Caving Block caving is an inexpensive bulk mining method where the ore is drawn by gravity and which is suitable for ore bodies which are low grade and are consistent in their grades Depending on how the ore is broken there are three block caving systems 1 The Grizzly system for fine material 2 the slusher system for coarser material

May 28 2022Sub level caving also allows for a slightly more selective extraction of the orebody than is attainable through block or panel caving Production rates achieved in sub level caving operations are typically lower than for block caves but higher than for stoping methods Caving is a non selective bulk mining method

Block caving was developed in the early 2000s in a collaboration by Newcrest Rio Tinto Freeport and Chile s Codelco At its Cadia mine in Australia Newcrest has dug down more than 1 km

Block caving mines require large horizontal extents that automatically cave when the orebody is undercut Large vertical extents ranging from 60 180m justify the use of level developments Grades should also be uniform In order for the rock mass to break there must be at least one horizontal and two vertical joint sets

There are three current methods that are considered to be caving methods Block caving Sublevel caving Longwall mining Sublevel caving and block caving have application to inclined or vertical massive deposits almost exclusively metallic or nonmetallic Longwall mining is used in relatively flat lying and tabular deposits such as coal

Block caving is a mining method that relies upon natural forces to break the rock The cave is initiated by an undercut where a large area beneath the mining block is removed gravity induced stresses then develop within the rock causing it to fracture The fracturing process is progressive and affects the entire rock mass overlying the undercut

Block caving has emerged as a cost effective method of mining large low grade mineral deposits The role of block caving Although the caving mining system was initially used for shallow orebodies it has recently been applied at depths of 2km underground

Sometimes block caving is chosen as the best mining method to continue ore extraction below an open pit that has reached its practical depth Other projects will utilize block caving from the start Other favourable conditions include the presence hopefully of vertical or steeply dipping and horizontal joint fractures that will naturally aid in the caving or collapsing process

Block caving is a large scale mining method that is particularly useful for mining low grade or disseminated ore bodies which are at too great a depth to be exploited through open cast mining This mining technique gets its name from the layout of the mine which divides the ore into large sections or blocks

The method is an attractive alternative when planning to develop a new mine or to extend the life of an open pit operation More and more mining companies are exploring block caving as it becomes increasingly difficult to find high quality orebodies close to the earth s surface
