mining conveyor belt tunnel for mining

mining conveyor belt tunnel for mining MC World Mining Client hired Hanlon Engineering Architecture, Inc to design a concrete reclaim tunnel to replace an existing horizontal 12′6″ diameter dilapidated corrugated metal tunnel The existing conveyor has a 36″ belt and was very tight in the geometry of the corrugated tunnelThe CR Tunnel Track belt tracker is suited to applications where mining conveyor belt tracking poses an ongoing issue to conveyor belt performance By deforming the mining conveyor belt, the CR Tunnel Track belt tracker forces the conveyor belt to maintain the desired position Best suited for short centered and reversing conveyors where belt tracking can cause problems with mining conveyor belt reliabilityMining Conveyor Belt Trackers

Tunneling conveyors Underground mining

Conveyor systems provide an efficient, reliable, costeffective and lowerrisk method of removing muck and spoil from tunnelling excavation sites Since the late 1980s, when the benefits of using conveyor systems in tunnelling projects first became apparent, we have been a worldwide leader in the manufacture and sale of conveyors designed and built to withstand the harsh conditions associated with tunnelThe interface between the TBM and the conveyor structure is paramount to successful tunnel excavation advance Material loading points and belt return configurations are designed specifically for each installation Tunnel conveyor structure installation is designed to facilitate conveyor mounting during TBM operation, thus enablingTunnelling Conveyor Systems miningkomatsu

Several hundred meters of newly excavated tunnel a week are not uncommon in mechanized tunnelling, depending on the geology The belt conveyors for removing the excavated soil or rock must keep pace A reliable belt conveyor system as a seamless interface between the tunnel boring machine and the jobsite aboveground is thus an essential factorMining Client hired Hanlon Engineering & Architecture, Inc to design a concrete reclaim tunnel to replace an existing horizontal 12′6″ diameter dilapidated corrugated metal tunnel The existing conveyor has a 36″ belt and was very tight in the geometry of the corrugated tunnel The new tunnel interior designed with a regular rectangular section with a width of 14′0″ could fit the reinstalled 36″ belt conveyor nowMining Reclaim Tunnel & Conveyors | Hanlon

Conveyors in Mining International Mining

Running at 6 m/sec, the 2 m wide belt conveyor system will carry the ore over almost 12 km The three principal conveyors, one 9,000 m long tunnel conveyor and two 1,000 m steep uphill conveyors (15°) feed the existing stockpile and in the future a new stockpile The contract also involves the extension of an existing conveyor lineJoy Global offers large capacity belt storage systems giving typically 400 800m of storage, facilitating 200 400m of tunnel advance without interruption In order to reduce the stoppage time associated with belt storage replenishment, the ability to complete two belt splices at the same time can, if space permits, be designed into the conveyor system Joy Global also offers belt reeling equipment to ease handling and rereeling operations when belting must be provided in cassette form due to road transportation limitations Specially designed belt support systems offer better belt control and optimize tensioning requirements These belt support systems are coupled with the highly efficient Joy Hydraulic Tension Master System, which provides controlled belt release and drive tension management Both are essential for maximizing speed of tunnelTunneling Conveyor Systems tunnelsonlinefo
