Block Caving  A Viable Alternative?  Golder

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. In block caving, a large section of ore is initially undercut by drilling and blasting, creating a large unsupported roof that will start to collapse under its own weight

Caving Methods  Mineral Production Activities

Block caving is a method which is used very successfully on large scale mines exploiting massive orebodies or pipes. An undercut is developed beneath a block of ore incorporating the entire footprint of the orebody, the block having a height of 200 to 300m.

Mar 09, 2018· Sublevel caving is a large scale mining method, suitable for large ore bodies with a steep dip. The setup is similar to long hole stoping except loft raises are not required. Also, mining starts at the top of the ore body and progresses downwards in a safe sequence.

Suglo Block Caving Method 1 BLOCK CAVING METHOD Area of Application The method is applied to large massive and disseminated low grade mineral deposits of large horizontal dimensions which are structurally weak. Both the ore and country rocks are weak and the ore is weak enough to cave under

Block Caving

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.

Underground Mining Methods and Equipment

Caving methods are defined as those associated w ith induced, controlled, massive caving of the ore body, the overlying rock, or both. Th e exploitation workings in caving methods are designed to collapse, with intentional caving of the ore and/or host rock. The three major caving methods are: Longwall mining Sublevel 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

The Block Cave Mining Method

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.

Block caving  Canadian Mining Journal

Dec 01, 2018· Another key advantage to an underground mining method like block caving,pared 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.

Sublevel caving   Underground Mining  Theory and

Jun 14, 2019· This mining method can be applied to numerous types of ore bodies with inclination from horizontal to vertical. If ore body is narrow its inclination should be steep in order to apply the method. It is desirable that ore is strong enough to minimize support requirements for sublevel drifts, while surrounding rock mass should be prone to caving.

An overview of block caving operation and available

Block caving technique is a mass mining method in which gravity is usedbinationwith internal rock stresses to fracture and break the rock mass into pieces that can be handled by miners. This method is normally applied to large, low grade ore bodies because of its low production cost and high capacity.

Block caving   QueensMineDesignWiki

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. The techniquemonly used to extract low grade copper, copper gold, iron and molybdenum ores although

Underground mining hard rock

Bulk mining methods . Block caving is used to mine massive steeply dipping orebodies typically low grade with high friability. An undercut with haulage access is driven under the orebody, with drawbells excavated between the top of the haulage level and the bottom of the undercut. The drawbells serve as a place for caving rock to fall into.
