Conventional mining involves several standard mining methods, modified for specific subsurface conditions as necessary once the ore level is reached. Boring machines with two or four cutting arms are efficient and effective mining methods for potash beds that are relatively flat and thickly uniform. One or two moveable arms mounted with a cutting “drum” are the most effective continuous miners for moderately inclined, undulating, or thickening-thinning potash seams.

Types of Continuous Mining Machines We Use

Borer and drum miners are the two most common types of continuous mining machines. Although they only cut a fixed seam thickness and width, borer miners apply uniform cutting pressure, have fixed cutting heads, and are more capable. Because drum miners have rotating cutting heads that cut sideways against the face, they can adapt to changes in ore thickness despite their lower capacity. Ore bodies with highly variable properties, such as rock bursts, and ore with other special requirements,

need to be drilled and blasted. In general, blasting is more effective than continuous mining at managing mine sites with significant variances in ore thickness but typically results in higher costs.

A conventional room-and-pillar design is standard in potash mines. In deeper room-and-pillar mines, stress relief mining (multiple entries with outer yield pillars) has proven highly effective in dealing with the plastic flow (of ore and salt host) or unstable roof conditions (mine back). Rooms and pillars are built along the potash seam, while pillars and timber support the roof of the potash mine. The original pillars collapse rapidly in many shallower mines, allowing the waste heaps to support the weight of the back, and allowing miners to return and extract the ore.

New players in the potash market are rare, regardless of the underground production method chosen. It costs over a billion dollars (US) to set up a conventional potash mine. A new mine’s entry shaft must be constructed without water entry, usually accomplished by freezing the ground.

Bridge The Gap

What is the safest method of mining?

Using underground mining, ore can be extracted safely, economically, and with as little waste as possible from below the surface.

Which method of mining is most cost-effective?

Mines near the surface of the earth are best suited to surface mining. Additionally, it is usually a more cost-effective mining method than underground mining.

How can we improve mining efficiency?
  1. Strengthen mine planning
  2. To achieve high-quality production, cut-off grades should be increased.
  3. The capital expenditures on properties with a lower production potential and a shorter mine life should be reduced.
  4. Reducing reserves may have both advantages and risks.
  5. Enhance the sequencing of mine sites to optimize them.
