Design methodology for underground Mining and Blasting

Within the context of this paper underground ring blasting refers to long hole blasting techniques as applied in mining methods such as bench stoping sub level open stoping and SLC including undercut blasting and drawbell blasting in the case of block and panel caving methods All of these methods have been fully described in Refs 5 and 12

The Actual Difference Between Surface and Underground Mining

Surface mining can be accomplished by the following main methods Open pit Mining Removing ore to leave a crater Quarrying An open pit mine for construction materials Strip Mining Ore is removed in parallel strips Mountaintop Removal Top of a mountain is blasted to remove deep ore Dredging Ore is removed from a river bottom The main methods of underground mining are

Mining techniques for companies surface

Mining Techniques is divided into two types surface mining and underground targets are divided into two categories of materials placer deposits and lode deposits If a mineral is stable chemically and is resistant physically it can be eroded from its primary hard rock occurrence and transported to river channels deltas or other sedimentary environments where it can be

Underground Mining Methods Resource

The backfill underground serves to keep the mine walls stable and also as the floor for mining the next slice Mining continues upwards towards the surface until the orebody is depleted Sublevel stoping Sublevel stoping is a mining method in which ore is blasted from different levels of elevation but is removed from one level at the bottom of the mine

Earth s Natural Resources Mining DoDEA

Shaft mining is the deepest form of underground mining It involves excavating a tunnel from the top to the bottom area of the mine From this tunnel the miners then dig long horizontal tunnels to get to the coal or other mineral ore The tunnels are dug deeper and longer until all the ore is extracted or it becomes too deep to worry about it
