Underground mining (hard rock) Wikipedia

Selective mining methods. Cut and fill mining is a method of short-hole mining used in steeply dipping or irregular ore zones, in particular where the hanging wall limits the use of long-hole methods. The ore is mined in horizontal or slightly inclined slices, and then filled with waste rock, sand or tailings

Types of Underground Mining Method Comparison

Mining Methods Boxhole Boring. Boxhole boring is similar to the raisebore method, but the drilling machine is located below the mineralization, so development is not required above the mineralization.From a drill chamber in waste rock below the ore, we drill a series of overlapping holes up through the ore zone and collect the falling ore from a chute in the extraction chamber.

A Brief Introduction to the Types of Surface Mining Methods

Mar 08, 2018· These surface mining methods are considered to be more efficient and economical in extracting minerals as compared to most methods of underground mining. In fact, it can extract almost 90% of ore from a deposit. For this reason, surface mining is the most widely used method

Mining : What is Mining? What are the 4 mining methods

Mining techniques. Surface mining. Surface mining is done by removing (stripping) surface vegetation, dirt, and, if necessary, layers of bedrock in order to reach buried ore deposits. Techniques of surface mining include: open-pit mining, which is the recovery of materials from an open pit in the ground, quarrying, identical to open-pit mining

Underground Mining Methods — New Pacific Metals

This type of mining is typically done upwards from lower levels, so the fill is also used to provide a new working level for further mining. Cut and fill mining can be expensive, but this method allows for highly selective mining with less waste rock or low-grade ores mined-out (which keeps production costs low).

Mining Techniques | Geology for Investors

These mining methods are used very commonly in Minecraft. The difference between quarrying and strip mining is that the process of quarrying involves a large rectangular or square strip, continually mined downwards with a staircase running along the side. This method got its name by its similarity to real world quarry sites.
