A surface coal mine in Britain before and during the reclamation process. Mine reclamation is the process of modifying land that has been mined to ecologically functional or economically usable state. Although the process of mine reclamation occurs once mining is completed, the planning of mine reclamation activities occurs prior to a mine ...

Automated coal handling systems should include manpower and equipment maintenance requirements in the evaluation of any layout. Overall operating costs in a material handling system are passed on to the consumer in the price of energy. ... are housed in a rectangular concrete reclaim tunnel extending along the entire bottom of the bunker and ...
Mobile systems and rail-mounted or tunnel reclaim systems, while operating concurrently, can create a two-product blend on the yard belt or tunnel belt within an accuracy of 5% to 10%. Systems described provide total redundancy to the principle reclaiming operation whether it's a rail-mounted more » bucket wheel stacker/reclaimer or a tunnel ...
The S-3 raw coal reclaim tunnel belt had a capacity of 2500 tons per hour. 9. Signs warning of stockpile danger were posted along the roadway approaching the reclaim stockpile. > 10. The certificate of death and autopsy by the Medical Examiner of West ia stated the cause of death was multiple injuries attributed to a crushing injury to ...
Glencore Coal Bulga Operation An AP Sensing Linear Heat Detection solution was selected to monitor surface and coal reclaim tunnel conveyors at the Bulga Coal Handling Plant, NSW, Australia. The customer, Glencore Coal, produces about 12 million tons of coal a year and required an advanced and durable system for

Sequential Tunnel. For stackers with an arc of greater than 60 degrees, reclaim conveyors in sequential tunnels provide greater reclaiming capacity. In this arrangement, the reclaim tunnel from one section of the pile intersects the tunnel for the next conveyor at an angle. The first conveyor discharges onto the tail end of the next …
The original coal-handling stockout and reclaim systems were designed to handle one coal type but were made compatible with future coal blending (Figure 1). Two stacking tubes were provided for ...
Tunnel Reclaim Conveyors offer operators on-demand access to material from their surge piles. This creates a continuous flow to processing plants even when upstream operations are suspended. Proper flow to crushing and screening equipment is critical for efficient and economic operations. Superior's tunnel reclaim systems are designed to ...

Incorporation of voids to the arch and a unique ring beam arrangement to allow for inclusion of coal valves to release coal from the stockpile above, onto the conveyor below. The second such reclaim tunnel supplied to Roche Process Engineering in as many years. Newpac built on the success of a similar tunnel at Foxleigh in Queensland.
The new tunnel interior designed with a regular rectangular section with a width of 14′-0″ could fit the re-installed 36″ belt conveyor now centered to allow for maximum space on both sides. A larger rectangular tunnel, electrical and mechanical upgrades improved maintenance and safety. Inside vertical clearance starts at 10′-6″ at ...
A coal reclaim tunnel (CRT) is usually built to facilitate transportation of coal continuously from stockpiles to coal barges and ships through a conveyor. Because of the possibility of methane and coal dust that appear in explosive range concentration inside the tunnel, the risk of fire and explosion can occur in CRT facilities, if the methane ...

air mixture down and out of escape tunnel • Coal-air mixture thins out (diluted non-flammable condition) at escape tunnel exit that reduces probability of ignition • No external high-pressure "bubble" forms external to escape tunnel opening - Therefore, external ignition of coal-air cloud not likely • Combustion front becomes unstable
The coal reclaim system comprised a stockpile located over a hopper which fed coal onto a conveyor in reclaim tunnel below via a clam shell style delivery …
The reclaim system included the construction of an underground tunnel with three chambers to accommodate a conveyor and stockpile discharger that delivers coal on to the shiploading system. GHD provided structural, mechanical and electrical design for the coal stockpiling and reclaiming system on behalf of the Gladstone Port Authority, and ...
