Also during the later stages of mining, recovery of ore left in a shaft pillar may be considered. In this regard, pillar mining is usually more expensive than stope mining and must be done with great care because of the ever-present need to protect the shaft. Small pillars may be left within the larger shaft pillar during pillar mining

Mining engineers stop short of their targeted cavern footprint so the secondary mining process can be initiated. By injecting hot brine into the cavern, the roof and walls begin to slowly dissolve the potash. During all stages of the solution mining process an oil blanket is injected into the cavern to prevent uncontrolled vertical mining

Mining is the extraction of economically valuable minerals or other geological materials from the earth surface. It may be from an ore body, lode, vein, seam, reef or placer deposits

Mining - Mining - Ventilation and lighting Ventilation is an important consideration in underground mining. In addition to the obvious requirement of providing fresh air for those working underground, there are other demands. For example, diesel-powered equipment is important in many mining systems, and fresh air is required both for combustion and to dilute exhaust contaminants

Modern opal mining Fast forward to today, and the process is similar, expect there is a great use of mechanied tools for digging, extracting, lifting, and sifting. For larger mines, a blower is often used which is like a very large vacuum cleaner that literally suck the clay-stone to the surface
