Principles of Longwall Mining

Strip mining. Strip mining, as the name describes, is a process of removing rock and soil in strips to get to the valuable mineral ores below.After miners extract the resources, they put back the leftover rock and soil, called mining spoils or tailings, to fill in the hole.. One way to replace tailings is to simply dump them; luckily, U.S. regulations require mining companies to replace ...

Mining - Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the ...

mining, dozers push the spoil uphill to cover the highwall before revegetation commences. Block-cut mining can be applied to either area or contour mining. This method differs from conventional area and contour mining in that blocks of overburden in excess of 70 ft (20 m) wide are removed as a unit and deposited in mined-out areas

The Environmental Science of Surface Mining

A conventional impoundment is a surface retaining structure designed to store both tailings and mine water, with the aim of reclaiming the water for use in the processing plant as required. There are principally two types of surface impoundments, a water retention type dam, and a raised embankment that has many configurations (Vick 1990).

Mining | Student Energy

The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.

Potash Mining Supply Chain Requirement Guide

Conventional mining usually occurs around 1,000 metres below the surface. Solution mining can access potash reserves at depths exceeding 1,600 metres below the earths' surface. The majority of Saskatchewan potash is mined by the conventional mining method, where large mining machines are used to extract the ore by cutting tunnels into the ore body.
