Opencast to underground iron ore mining method
2018-7-28 Abstract. At the end of the open-pit mining process in large metal mines, the mining model must change from open-pit mining to underground mining, but the mutual interference between the two mining models leads to poor production safety conditions

2020-5-15 Open-cast mining is one of the most popular surface mining methods mostly employed for bedded deposits. The kind of minerals or rocks mined this way are found near the surface; where the overburden (surface material covering the valuable deposit) is relatively thin or the material of interest is structurally unsuitable for tunneling.

Open Cast Mining JJ Mining
Opencast mining is a surface mining operation where we extract minerals from an open “pit” in the ground. This method of mining is the most popular for mineral mining and doesn’t require the use of extractive methods or tunnel digging. Opencast mines are used when minerals or ores are found close to the surface of the earth.
