What Are The Methods Of Mining

Methods of Mining 1. Open Cast Mining-Method of extracting minerals which are near the earth’s surface. Types a) Stripping-Stripping off of the unwanted material lying on top of the mineral deposit and then digging to remove the mineral bearing rock if it’s soft or if it’s hard explosives may be used to loosen it and then huge power shovels are employed to dig up the mineral deposits.

Minerals Free Fulltext A Method Of Backfill Mining

The traditional backfill mining method is a technology developed by the general trend of green coal mining, but with a high cost and an impact on production efficiency. This paper proposes a structured backfill mining method with high-water materials and pillars. The evolution of roof pressure appearance is assessed through the sensor and monitoring system in the hydraulic support.
