Underground mining is carried out when the rocks minerals or precious stones are located at a distance far beneath the ground to be extracted with surface mining. To facilitate the minerals to be taken out of the mine the miners construct underground rooms to work in.

20191221Waste Rock Dump Management and Stability Evaluation D Olivier SRK The management of mine waste dumps has historically been assigned mainly to the onsite mining operations. In recent years focus has turned to a more scientific approach to waste rock dump management and the auditing of these manmade structures.

202032There are four main mining methods underground open surface pit placer and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels beach sands or other environments. Insitu mining

2020227Before launching into a comparison of hard rock lithium mining vs. harvesting lithium brines its important to point out that hard rock mining can be preferable to alternative methods but usually only where hard rock mining is already entrenched in places like the Greenbushes mine located in south Western Australia
The underground mining methods we use include room and pillar narrow vein stoping and largescale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.
Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 99.99 pure copper called cathodes which will ultimately be made into products for everyday use.The most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different
