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. The raw ore is then conveyed to a production hoist where it is transferred to the surface for processing.

Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as salt, coal, or oil sands.
Conventional Discontinuous Mining Methods . We are a large scale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment, milling equipment, mineral processing equipment and building materials equipment.

Alternative mining pilot tests in narrow veins:pany is currently carrying out pilot testing of mining methods for narrow veins, using the sublevel stoping and conventional mining cut and fill methods, in order to determine the optimal mining method for these types of structures.
Of the 11 potash mines in Saskatchewan, nine are conventional underground mining operations, which require underground equipment and personnel. The other two are solution mines, which involve pumping heated water through the ore body to dissolve the potash and pumping the resultant brine solution to a refinery for extraction.
The fifth deepest mine in the world, the Kusasalethu operation employs conventional mining techniques in a sequential grid layout. With a proven reserve of 2.7Moz of gold grading 0.208oz/t and a probable reserve of 4.4Moz of gold grading 0.172oz/t, Kusasalethu can be expected to continue operating for many more years.

Large scale mechanised mining methods we use include: long wall mining, where a long wall of coal is mined in a single slice, usually by a large machine. sub level caving, where levels of the ore are blasted by explosives and block caving, where large areas of the ore body are blasted and then extracted with the assistance of gravity. We use these three different types of underground mining

However, when a seam exceeds these thicknesses, its extraction usually involves dividing the seam into a number of slices and mining each slice with longwall, continuous, or conventional mining methods. The thickness of each slice may vary from three to four metres. Many variations exist in the manner in whichplete seam is extracted.
The mining method is based on six nested sequential open pits 1a, 1b, 2, 3, 4 and 5. The final pit, 5 will measure some 1.1 km by 750 m, with a maximum depth of 130 m on the final high wall. The total surface area of the final pit 5 will be approximately 0.55 km 2.

These mining methods fall into three broad categories, namely conventional, mechanized and hybrid mining Figure 1. Conventional mining includes up dip, down dip and breast mining. Mechanized mining includes room and pillar, room and pillar with T cut, extra low profile XLP and continuous rock cutting technology.
