This mining method precipitously dips strata for mineralization. This method blasts rocks with total and heavy charges with a large diameter of 165 mm. VCR's blasting creates a cone-shaped opening in the targeted rock mass to let the materials be mined quickly. The blast hole of VCR mining follows the method of 4.0 x 4.0 m pattern.

A framework for Off-Earth mining method selection

The deposit characteristics used for selecting mining methods are the ore body shape, thickness, dip angle, grade distribution and the rock strength of the ore zone and surrounding rock. These characteristics are assigned numerical scores (0–4) depending on how well each mining method will be suited.

the mining technologies currently in use on Federal leases and the potential for commer-cial mining technologies to extract Federal coal reserves from deep underground seams. The chapter discusses: three surface mining techniques that are used in the West: 1) area strip, 2) open pit, and 3) terrace pit; two methods of underground mining in

Shrinkage Stope Mining, Mining Methods, Mining …

Shrinkage stope is a generic term used in mining to portray the process of mining upwards from a lower to an elevated horizon, leaving broken rock in the excavation created. The broken rock acts as a working platform and assists to stabilize the excavation by supporting the walls. The method may be used for ore mining in shrinkage stopes, for ...

4.3.1: Surface Mining Methods | ABC 123: Testing Site / …

There are two important sub methods for open cast mining. One is known as area mining, and is applicable when the terrain is relatively flat; and the other is contour mining, better suited for mountains regions. A few examples of commodities mined by this method include coal and phosphate. Quarrying. Quarrying is a method of extracting ...

4.3.2: Underground Mining Methods | ABC 123: Testing …

4.3.2: Underground Mining Methods. Underground mining methods become necessary when the stripping ratio becomes uneconomical, or occasionally when the surface use of the land would prohibit surface mining. Underground methods are traditionally broken into three classes: unsupported, supported, and caving methods.

The Goldex Mine mining method - Conference Papers

hangingwall made these methods not well suited. Block caving was nevertheless reconsidered in 2002. Numerical modelling showed that even using test stope as the undercut, the cave would stall before the orebody was totally recovered as can be seen in Figure 7. The results of this analysis confirmed that a blast assisted mining method was necessary.

Selection of mining method - QueensMineDesignWiki

Selection of mining method. Context: The selection of a mining method for a given orebody can be a challenging assignment and may need to address personal bias for or against a particular method.The selection of the mining method may also need to occur prior to the completion of desired geotechnical or ore value determinations.

Geological and geotechnical aspects of underground coal …

The major advantages of the longwall mining method include its suitability for mining at greater depth, higher recovery, and higher production rate compared to room and pillar. ... As an underground method, room and pillar mining is most suited to black coal deposits where the strip ratio is greater than 20:1, for reasons already discussed.

Cut and Fill. It is a short-hole mining method, used in ore zones that are irregular or steeply dipping. The ore is dug out in slightly inclined slices or horizontally. And sand will fill it, waste rock, or tailing. This method is a selective and expensive one. It has the advantages of low ore dilution and loss.
