 · Open-Pit. As the name suggests, open pit mining involves mining minerals or ore that can be found near the surface layer of the site. That being said, some quarries can be over 1000 meters deep. This form of mining doesn''t require tunnelling into the earth and is a simple method of mining that yields high production rates. .

A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

 · What is open pit mining? Open pit mining is the most common mining technology when it comes to new mines. In this technique, the soil is excavated and the mineral separation and the remaining soil material occurs on the surface. The first step in this process is the extraction of the ore (beta with high mineral grade).
