In situ recovery, an alternative to conventional methods of mining: Exploration, resource estimation, environmental issues, project evaluation and economics
A common method of mining such vertical ore bodies is stull stoping, see below. In shrinkage stoping, mining proceeds from the bottom upwards, in horizontal slices (similar to cut and fill mining), with the broken ore being left in place for miners to work from. Because blasted rock takes up a greater volume than in situ rock (due to swell

The CEO of Vancouver based EnviroLeach Technologies says the new approach is also the biggest innovation for conventional gold mining in 150 years. “The advent of cyanide in the 1870’s was the biggest innovation in all of mining history, and this challenges that,” says Duane Nelson. “Our technology has equal to or better leach kinetics than
Conventional Methods of Surface Mining. Open pit mining and strip mining are the two major categories of surface mining which account for more than 90% worldwide surface mining production. The primary differences between these mining methods are the location of the ore body and the mode of mechanical extraction. For loose rock mining

There are conventional underground mining operations; Western Canada's potash deposits occur in the Middle Devonian Prairie Evaporite formation at depths in excess
this goal more efficient mining methods need to be applied, for conventional mining will not be able to fulfill the company’s aims. With the improvements in trackless low profile machinery it is now possible to safely produce at a significantly reduced cost, and improved productivity. Mechanized bord and pillar mining is thus considered as a supplement to conventional mining

In Situ Recovery (ISR) In situ is a Latin word that literally means “in the place.” Unlike conventional mining methods, in situ recovery (ISR) removes the ore while leaving the rock “in the place.”
Potash is a relatively soft rock material that can be mined or extracted in two different basic methods: Conventional mining access the ore zones by shaft or decline and extract the bulk ore by standard mining equipment – similar in technique to underground coal mining.
