block caving mining method

Coal miningCoal mining Coal mining Choosing a mining method The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many.Block cavingAnother key advantage to an underground mining method like block caving, as compared to open pit methods, is the large reduction in surface waste disposal needs As open pits get deeper, their ratios of waste rock to ore often get higher and the waste must be.Sublevel Caving Mining MethodSublevel Caving Sublevel Caving is one of many different methods for underground hard rock mining It is a large scale mining method suitable for large ore bodies with a steep dip and a rock mass with a host rock in the hanging wall will fracture under controlled conditions.Sublevel cavingSublevel Caving Safety Sublevel caving is a relatively safe mining method since the operations take place in small areas at a time and are highly mechanized The uniformly distributed nature of generally 5mx37m sublevel nature of drifts aids in the safety of this mining method.Block Caving Mining SpecializationLater in the schedule, the company is also targeting the outlying Kucing Liar orebody for block caving In the meantime, FCX converted its DOZ orebody, which it began mining in 1989 using open stoping, to block caving in 2000, with production expected to continue until 2019.Underground Block Caving A Guide for InvestorsBulk mining methods are a necessary component of economically mining massive, low grade porphyry copper, gold, molybdenum and diamond deposits, and block caving is the method of choice.Sublevel cavingSublevel Caving Safety Sublevel caving is a relatively safe mining method since the operations take place in small areas at a time and are highly mechanized The uniformly distributed nature of generally 5mx37m sublevel nature of drifts aids in the safety of this mining method.

Introduction to Block Caving

This course provides a general introduction to the block cave mining method, covering advantages and disadvantages, basic elements of block caving, design issues, operational issues, safety issues, and economic issu *** This is a premium course which has been peer reviewed by a committee appointed by the Canadian Institute of Mining.

Underground Mining Methods — New Pacific MetalsBlock Caving Block caving is essentially the underground version of open pit mining It’s the only underground mining method that can reach similar production rates to surface mining operations, up to over 100,000 tonnes per day The method involves undermining an ore body, then allowing it to collapse under its own weight.Block cavingJul 14, 2014· Introduction The one u/g mining method that has the potential to rival surface mining in output and cost is block caving Block caving is the mining method in which masses, panels, or blocks of ore are undercut to induce caving, permitting the broken ore to be drawn off below If the deposit is overlain by capping or bounded by drawing the ore.Block Caving Cu Au PorphyryCave Mining Cu Au Porphyry There are over 45 cave mining projects in various stages of studies and development around the world Cave mining methods will be the underground method of choice in the future It is only relatively recent that this mass mining method, despite 70 years of use, has begun proving its potential.New to our Series!Block caving as a mining method in its own right, was first used in Michigan USA over a century ago Tthe modern form of the method evolved in the early 1940s when it was used in relatively weak and near surface ore bodies, predominantly in low stress environments where gravity was the dominant ore breakage and caving mechanism.Block Caving Method Underground Mine Design ,Describe the Block Caving Method Block is the mining layout which divides the orebody into sections Caving of the rock mass is induced by undercutting the block >the rock section underneath the block is fractured by blasting which destroys its ability to support overlaying rock.The new building blocks of block cavingBlock caving is being looked to as one method of bulk mining to access these ores, as it is recognised as one of the most economic underground mass mining methods to extract deep, low grade.Cave mining thestateoftheartCavemining thestateoftheart byDHLaubscher* Introduction Cavemining refers toallmining operations in whichtheorebody cavesnaturally after undercutting andthecavedmaterial isrecovered through drawpoints Thisincludes blockcaving, panelcaving, inclined drawpoint caving, and frontcaving Cavingisthelowest cost underground mining method provided.
