Block caving. Block caving is a large-scale mining method that requires a longer development stage than any other underground mining method. This method blasts a gap at the bottom of the rock mass which causes the rock above to break up and collapse to fill the void while the surface of the mie caves inwards. Cut and fill mining.

Inside block caving: the deep mining method of the future?

24.02.2020Block caving could be "the mining system of the future," according to Fidelis Suorineni. Block caving is a mining system which involves undermining an ore body and then allowing it to collapse under its own weight, a process that opens access to deeper deposits. Professor Fidelis Suorineni of the Nazarbayev University School of Mining and

Block Caving

10.07.2018Block cave mining operating costs are typically in the order of one tenth of what other underground mining methods cost, largely driven by economies of scale where production rates can reach 30,000 to 100,000 tonnes per day. In addition, drilling and blasting costs are far less, and there are no backfilling costs.

01.07.2018airblast in block caving situations is a very dangerous situation with potential loss of life for operators and damage to mining equipment. 1 airblasts occur when air pockets are present within the material that is currently being extracted through the drawpoints ( fig. 1 ). 2 as the material close to the drawpoints (defined as the muck-pile)

Block caving: When real life doesn't happen like the animations

Drawpoint hang-ups represent significant impediments to getting the resource out of the ground in the safest, most expedient way, while oversize blocks of ore are tough for scoops to handle. So the business case for keeping the ore flowing is compelling. A MacLean blog post on addressing the gap between block caving animations and block caving real-life.

THE OPTIMAL BLOCK SIZE IN THE BLOCK CAVING MINING

The impact of hydraulic radius on caving showed that square blocks are best suited for caving. While using square blocks, the relationship becomes a quadratic inequality with one unknown which is easy to be solved. Proved with a slight decrease in the safety factor of about 5%, we can increase the block length about 2 times while safety remains unchanged. Considering the

Block caving is a complex method ruled by the dynamics of caving and the breakage of the rock mass towards the surface due to ore extraction. Conventional block caving operations have been changing or depleting and consequently new deposits have appeared with new challenges, such as lower grades and greater depths.
