Dan Gleeson looks at some technologies eradicating or reducing its use in metal extraction processes 16 EXPLOSIVES & BLASTING Having sweated all the assets possible to bring down their cost base, mining companies are now addressing the front end of the process to cut costs further. Dan Gleeson looks at how the explosives and blasting sector is responding 28 FUELS & OILS Paul Moore looks at some of the recent innovations that have vastly improved fuels and oils management, storage and delivery 40 ENGINES As more companies talk up the use of dieselalternatives in the mining engines sector, one must ask: how long will the combustion engine last in this new ‘green’ environment? Dan Gleeson looks for an answer 46 GROUND SUPPORT Paul Moore looks at key developments including the use of pumpable resin with bolts & SDAs for rock reinforcement 55 NARROW VEIN & LP MINING Dan Gleeson looks at some of the conventional – and unconventional – ways metals and minerals can be extracted from narrow vein and low-profile mines 64 TYRES The mining tyre industry has proven resilient in the face of COVID-19, while the ramp up of AHS fleets means there will be some interesting results for tyre wear, reports Paul Moore 71 SLOPE STABILITY MONITORING Paul Moore looks at slope stability monitoring, focussing on methods being deployed to monitor tailings storage facilities in the wake of the Brumadinho TSF failure but also the latest in open pit wall surveying with radar and laser 78 HOISTS There are some really big projects set to come on-line in the near term with record hoisting capacity, whilst on the technology side there are still some new ideas, reports Paul Moore 85 VENTILATION There is more to underground mine ventilation than volume, Dan Gleeson reveals 16 COVER: Sandvik AutoMine ® Surface Drilling is an automation system for autonomous and teleremote operation for a wide range of Sandvik iSeries surface drill rigs. It aims at improving safety, reducing cost, and increasing productivity. One operator can control a fleet of drill rigs and the system can expand from a line-of-sight setup to control room operation from miles away. It dramatically improves the working conditions and immediate safety of the operator while keeping mine personnel out of hazardous areas. This reduces the operator’s exposure to noise, dust, and vibration and the hazard of working close to highwalls. www.rocktechnology.sandvik www.im-mining.com IM MINING ENGINES SLOPE STABILITY EXPLOSIVES & BLASTING FUELS & OILS MINING TYRES DEEP MINING - VENTILATION & GROUND SUPPORT JULY/AUGUST 2020 AROUND THE WORLD 3 The Leader 4 World Prospects 92 Forthcoming Events IBC Classifieds JULY/AUGUST 2020 | International Mining 1
