mining equipment and technology used in block caving

Block Caving Challenges Transporting ore underground presents significant challenges depending on the excavation method used Underground operations at the Mongolian mine will use the "block caving" method In block caving a large section of rock is undercut The ore then collapses – or "caves" – gradually under its own weight The resulting rubble funnels through a series of

Study on the Rock Mass Caving and Surface Subsidence

To deeply understand the mechanism of the rock mass caving and associated surface subsidence during sublevel caving mining the Xiaowanggou iron mine was selected as an engineering project case study The study area was analyzed by means of an in situ geological investigation and numerical simulation First a borehole television (BHTV) system and a GPS monitoring system were used to

Additional sub-surface mining methods include hard rock mining which is mining of hard rock (igneous metamorphic or sedimentary) materials bore hole mining drift and fill mining long hole slope mining sub level caving and block caving Machines Heavy machinery is used in mining to explore and develop sites to remove and stockpile

Australian mining

Mining is a significant and important part of Australia's economy The Australian mining industry origins stem back to the early days of Australia's settlement when first settlers identified sources of coal in 1797 near Newcastle New South Wales (Nobby's Head) Coal was first used as a source of heating for the emerging economy and the rich Hunter Valley seams (often protruding from the

sublevel caving mining method

Cave mining (both block caving and sub-level caving) which is currently used at Petra's underground mines in South Africa is a well-established and safe mechanised mining method that was first introduced at Kimberley South Africa in 1951 Contact Supplier Sublevel caving - ScienceDirect Underground mining in Sweden produces annually about 40 million tonnes of ore and rock the principal

Block caving has emerged as a cost-effective method of mining large low-grade mineral deposits The role of block caving Although the caving mining system was initially used for shallow orebodies it has recently been applied at depths of 2km underground According to Suorineni "caving heights have also increased drastically from about

Some mining machinery manufacturers are also taking advantage of the growing interest in the method with releasing a new block caving ore handling system late last year The automated system increased the already safer mass mining method by not only improving the way in which the ore is moved but removing the miner from the face

Engineers and manufacturers of specialised mining equipment have created a suite of mining equipment that rivals anything dreamed of 20 or 30 years ago Advances in engineering have produced haul trucks draglines shovels and mineral processing equipment that defies logic in terms of sheer size carrying and loading capacity "a new era of boggers and jumbos" As open-cut mining technology

Blasting equipment is used for both underground and open pit mining operations and is known to be one of the most hazardous aspects of the job For mining operations to be successful good blast designs are absolutely vital as poor practices and excessive explosives can result in damage to rock structures causing unwanted caving

The development of mineral processing equipment and mineral processing technology is synchronized the process is dominant and the equipment is the foundation The birth of a new type of mineral processing equipment often leads to changes in the beneficiation process The technical level of the equipment is not only the premise of the process level but also affects the smooth flow and
