25/07/2018· Block caving is a new alternative method of developing new mines or extending the operation of open pits. Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight.
Block Caving . Block caving is large-scale mining method that allows for huge volumes of rock to be extracted efficiently. However, the development time before production starts is longer compared to other mining methods. By drawing rock from the extraction level in the lower part of the mine, a gap is created. Absence of support for the
Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses.
23/10/2014· Caving Underground Mining Methods (longwall, Sublevel caving, & Block caving) 1. This material is intended for use in lectures, presentations and as handouts to students, and is provided in Power point format so as to allow customization for the individual needs of course instructors.
The mining method selected is determined by the size, shape, orientation and type of orebody to be mined. The orebody can be narrow vein such as a gold mine in the Witwatersrand, the orebody can be massive similar to the Olympic Dam mine, South Australia, or Cadia-Ridgeway Mine, New South Wales. The width or size of the orebody is determined by the grade as well as the distribution of the ore. The dipof the orebody also has an influence on the mining method for exa
Block caving is an underground mining method that uses gravity to exploit massive, steeply dipping ore bodies located at depth. These ore bodies are generally low grade in nature and are too deep to be extracted through open pit mining.
Block caving is employed principally for mining low-grade ores where the inevitable loss of some ore and some dilution with capping and wall rock are permissible and where mining must be done on a large scale and at a lower cost than can be obtained by the use of supported-stope or other selective mining methods.
1/12/2018· Another key advantage to an underground mining method like block caving, as compared to open pit methods, is the large reduction in surface waste disposal needs. As open pits get deeper, their ratios of waste rock to ore often get higher and the waste must be placed in ever-increasing surface storage areas. The amount of waste rock generated
14/07/2014· Block caving method 1. Block Caving Method Virendra Suryawanshi [email protected] 2. Introduction The one u/g mining method that has the potential to rival surface mining in output and cost is block caving.
Block caving is a gravity-based underground mining method that involves breaking up the rock mass located at depth into pieces. This method is particularly suitable for low-grade minerals or with disseminated mineralization.
12/08/2019· Block caving is essentially the underground version of open-pit mining. It’s the only underground mining method that can reach similar production rates to surface mining operations, up to over 100,000 tonnes per day.
25/07/2018· Block caving is a new alternative method of developing new mines or extending the operation of open pits. Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight.
10/07/2018· Another key advantage to an underground mining method like block caving, as compared to open pit methods, is the large reduction in surface waste disposal needs. As open pits get deeper, their ratios of waste rock to ore often get higher and the waste must be placed in ever-increasing surface storage areas. The amount of waste rock generated
Block caving is a large-scale underground mining method applicable to the extraction of low-grade, massive ore bodies. With the amount of literature available on block caving this report identifies the need to provide a simple understanding of the process.

Caving Methods of Mining. There are three distinctive methods of working large deposits that involve, in some way, the factor of caving. Slightly different names are in use, but those that are simple as well as descriptive are top slicing, sublevel caving, and block caving. In a discussion of these methods, three things must be borne in mind
Sublevel Caving . Sublevel Caving is one of many different methods for underground hard rock mining. It is a large-scale mining method suitable for large ore bodies with a steep dip and a rock mass with a host rock in the hanging wall will fracture under controlled conditions.
Block Caving 2. Underground Mining Machinery Glossary Bibliography Biographical Sketches Summary The first section gives an overview of underg round mining methods and practices as used commonly in underground mines, including classification of underground mining methods and brief explanations of the techniques of room-and-pillar mining, sublevel stoping, cut-and-fill, longwall mining
Block caving is being looked to as one method of bulk mining to access these ores, as it is recognised as one of the most economic underground mass mining methods to extract deep, low grade
In underground mining, block caving is the only method with the costs comparable to surface mining methods, especially open pit mining. A switch from open pit mining to block caving mining could
20/07/2019· Block caving is group of mining methods that has been developed from the sublevel caving. As its name is saying, ore block is caved by influence of the gravity and drawn at its bottom. This group can be divided into conventional block caving and panel caving that is dominant. Some authors consider panel caving as separate mining method, while
these mining methods. As caving has proven to be a safe and effective mining method, its popularity has increased around the world.” BLOCK ANd pANeL CAVING Block caving is an underground mining method that uses gravity to exploit massive, steeply dipping orebodies located at depth, particularly those with disseminated mineralisation or that are
Cave mining is typically used to mine copper, copper-gold, iron and molybdenum. It can also be used in the extraction of kimberlite and lamproite in the mining of diamonds. Block Cave Mining Techniques. The most commonly used cave mining technique is block caving. Block caving is a large-scale mining method that is particularly useful for
Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses. This
Block-caving, while technically challenging, is one of the safest and most cost-effective methods of mining ore from deep below the ground. The block caving mining method at Hugo North will make Oyu Tolgoi a long-life, sustainable producer and a major contributor to the world copper market.
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 and 3) the
Sublevel Caving Safety. Sublevel caving is a relatively safe mining method since the operations take place in small areas at a time and are highly mechanized. The uniformly distributed nature of generally 5mx3.7m sublevel nature of drifts aids in the safety of this mining method. To increase the stability of drifts in competent rock is
