Sublevel Caving . Sublevel Caving is one of many different methods for underground hard rock mining. It is a largescale 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.
stoping, cutandfill, longwall mining, sublevel caving, and block caving. The second section describes underground mining equipment, with particular focus on excavation machinery such as boomheaders, coal cutters, continuous miners and shearers. 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.
Jun 15, 20180183;32;7. Sublevel caving. Sublevel caving is a method often evaluated in parallel with block and/or panel caving options. It requires multiple levels of development and ongoing ring blasting for production. Sublevel caving allows for a more selective extraction but typically achieves lower production rates than block and panel caving methods.
Discover GEOVIA PCBC, a comprehensive tool used by mining companies involved in block cave planning for feasibility studies, design and production management. PCBC is used by virtually every mining company involved in block caving who depend on it to improve profits through better mine plans, schedules and production management.
More and more mining companies are using big data and block caving to open up a wealth of new discoveries. Yoana Cholteeva speaks with Professor Fidelis Suorineni from the Nazarbayev University School of Mining and Geosciences in Kazakhstan about
Describe the Block Caving Method Block is the mining layout which divides the orebody into sections. Caving of the rock mass is induced by undercutting the block. gt; the rock section underneath the block is fractured by blasting which destroys its ability to support overlaying rock.
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.
Jul 25, 20180183;32;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.
Jul 10, 20180183;32;In the right conditions, the advantages of block caving make it an alternative that is now being considered more often, such as at Seabridges KSM Project. Block cave mining is an underground mass mining method that allows for the bulk extraction of large, relatively lower grade, ore deposits with substantial vertical dimension.

Dec 01, 20180183;32;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 everincreasing surface storage areas.
Block Caving . Block caving is largescale 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.
Cave mining is typically used to mine copper, coppergold, 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 largescale mining method that is particularly useful for
Some block caving operations have mining costs that are less than those of open pit mining operations, which is considered to be the cheapest mining method. Due to high dilution and low recovery, block caving should be used for large, steep, and lowgrade ore bodies.
Jul 14, 20140183;32;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 the mining method in which masses, panels, or blocks of ore are undercut to induce caving, permitting the broken ore to be drawn off below. If the deposit is overlain by capping or bounded by drawing the ore.
Cut and fill mining is a method of shorthole mining used in steeply dipping or irregular ore zones, in particular where the hanging wall limits the use of longhole methods. The ore is mined in horizontal or slightly inclined slices, and then filled with waste rock, sand or tailings.
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
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
Block caving is employed principally for mining lowgrade 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 supportedstope or
