  • Cave Tracker Mining3

    The Cave Tracker system, developed by Mining3, Newcrest Mining, Rio Tinto and Elexon, uses magnetic beacons embedded in the orebody which are spun at a particular speed to generate a magnetic field. It eliminates the need for battery power and can be detected from over 200m away through broken rock.

  • Block Caving Canadian Mining Journalcanadian Mining

    Dec 01, 2018 In block caving, a large section of ore is initially undercut by drilling and blasting, creating a large unsupported roof that will start to collapse under its own weight and instability, The broken ore then breaks apart and falls into a series of pre-constructed funnels, or drawbells, and access tunnels developed underneath the caving rock mass to form ore extraction drawpoints.

  • Mobile Rockbreaker Maclean Engineering

    Safe and efficient breaking of ore flow blockage is of prime importance for sustained underground production and profitability, particularly in block cave mines. The MacLean mobile rock breaker is the latest addition to the MacLean fleet of ore flow equipment and, with it, companies now have a one-stop solution for all their block cave mine production needs.

  • Underground Mining Methods And Equipment

    Caving methods are defined as those associated w ith induced, controlled, massive caving of the ore body, the overlying rock, or both. Th e exploitation workings in caving methods are designed to collapse, with intentional caving of the ore andor host rock. The three major caving methods are Longwall mining Sublevel caving

  • Mining Methods Block Caving Geology For Investors

    Dec 12, 2019 Block gravity caving is a bulk underground mining method, which allows large low-grade deposits to be mined underground. This method involves undermining the orebody to make it collapse under its own weight into a series of chambers from which the ore extracted.

  • Smart Marker System A New Tool For Measuring Underground

    In the past, measurement of ore flow in block and sublevel caves has been performed with passive markers often made from steel pipes embedded into the orebody. Extracting passive markers along with the ore is labour intensive and often requires many years of commitment.

    Caving methods are varied and involve caving the ore andor the overlying rock. Caving mining is advantageous in that it maximizes ore recovery as little ore as possible is left behind the method comes with significant problems Surface subsidence in the case of shallow mines. Rock-bursts underground, causing injury and death in deep level ...

  • Sublevel Caving Queensminedesignwiki

    Sublevel Caving is one of the most advanced mining methods. This method is usually undertaken when mining the orebody through an open pit is no longer economically viable. In Sublevel Caving, mining starts at the top of the orebody and develops downwards. Ore is mined from sublevels spaced at regular intervals throughout the deposit.

  • Study On The Ground Movement In An Openpit Mine In The

    The combined surface and underground mining method is typically used in an open-pit mine for better production and profits. However, the improved scale of mining operations at the combined mining conditions results in even more intensive strata movement and massive ground damages. This paper assesses the progressive development of the characteristics of roof movement with the longwall face ...

  • Sinkhole Solving Drainage And Erosion Problems

    3. Underground Flow or Spring. Sometimes running water can be heard in a sink hole. If a sewer or water pipe leak is not suspected, the water is likely from an underground spring that is uphill from the depression. It has eroded away soil under the surface causing an underground cavity. The ground surface settles into the cavity causing the depression.
