Coincidentally, the 300th AC-VFD shuttle car – a 10SC32BC model – is being shipped to Jim Walter Resources' underground coal mine in Brookwood, Alabama, not far from where the very first shuttle car of its type went into operation just four years ago at Drummond Coal's Shoal Creek Mine in Adger, Alabama.
Due to the successful application of roof bolter canopy air curtains (CACs) to protect roof bolter operators from high levels of coal mine respirable dust, a shuttle car CAC is currently being developed. Since a shuttle car consistently trams from the continuous miner to the feeder and back at a speed up to 9.66 kph (6 mph) or 2.68 m/s (528 fpm), it …
continuous mining operation helps in great increase in the development of output and avoid of dangers due to roof fall, side fall and any other kind of dangers. The continuous miner loads the coal into the shuttle car and car transports the coal to desired spots. The whole machinery is powered with load canter.

14. Working system of CM In this technology, mining takes place by "Place Changing System". Five heading panel is optimum. Gallery width should be minimum 5m The continuous miner cuts and load coal to shuttle car at a 'place'. For developing full width of gallery, CM cuts in two passes at a place. The shuttle car hauls the load to the …
The average total life-cycle cost of the battery hauler per ton hauled is R 5.89 more than that of the shuttle car. With the projected annual requirement of 190 000 tons per month per machine, the average operating costs would be R3.89 per ton and R2.98 per ton for battery haulers and shuttle cars respectively. Figure 3 shows the life-cycle costs.
By allowing mine operators to phase in the installation of proximity detection systems over a 36-month period, the final rule provides coal mine operators sufficient time to obtain necessary modification to the existing technology, obtain necessary approvals, install proximity detection systems on continuous mining machines, and train miners.
In room and pillar mining, the most common type of underground coal mining, coal seams are mined by a continuous miner that cuts a network of "rooms" into the seam. As the rooms are cut, the continuous miner simultaneously loads the coal onto a shuttle or ram car, from which it will eventually be placed on a conveyor belt that will …
Upgrades. First introduced in 1938, Joy shuttle cars continue to be the gold standard for batch haulage vehicles in the underground mining industry.

Best of all, it's the only pickup truck engine certified by MSHA for use in coal and metal/non-metal mining for all 50 states. By offering an emission reduction, the 175-hp Cummins will enable mine operators to reduce their annual expenditure on mine ventilation by $16,000 to $18,000 per year for each Ram vehicle in their fleet.
Elevated concentrations are encountered at the ram dump car operator position when the car is being loaded by the continuous miner. Recorded air velocities …

During the last few decades, the mining industry has increasingly turned to autonomous systems in its efforts to modernize and advance mining methods and techniques. Vehicle automation in such complex working environments can play a critical role in improving worker safety and mine productivity. Moreover, as the global demand for minerals …
The coal thickness varies from 2.8 to 4.0 m. Depillaring at the Pinoura Mine involves increasing the galleries width to 6.5 m for manoeuvrability of continuous miner and the quad-bolter attachment compliments the need for instant roof support. After widening of the galleries, the w/h ratio varied from 5.5 to 7.0.
With 10 faces, West ia remains the longwall leader, followed by Illinois (6), Pennsylvania (6) and Alabama (5). Looking at the numbers, the average U.S. longwall mine operating in coal produced 5.09 million tpy in 2019 compared to 5.11 million tpy in 2018. On average, it has a cutting height of 96.4 in., a panel width (or face length) of ...
5.1.2a: Shuttle Cars and Bridge Conveyors Shuttle Cars. Shuttle cars are a low-profile intermediate haulage option used predominantly in underground coal and some industrial minerals mines. Ore is loaded into the shuttle car at the face, and then it trams a relatively short distance, dumps its load, and returns to repeat the cycle.
A Australian-made battery-powered car is leading the charge to remove diesel engines from underground operations. ... Tomcar Australia, the firm that set out to make a car ideally suited to the underground mining environment, has come up with an electric model. The initial Tomcar prototype was a diesel driven vehicle that looked …
Shuttle Cars With over 100 units in the field today, Joy shuttle cars are available with an optional remote control system. Remote control permits deeper cuts as the shuttle car, now unmanned, can follow the miner under unsupported roof. This significantly improves the overall productivity of a room and pillar section.

In 1876 Joseph A. Jeffrey and others formed a partnership to build the world's first coal mining machines. That business eventually became The Jeffrey Manufacturing Company. The Company later expanded by acquiring Galion Iron Works, a maker of road-building machinery. In 1974 the Company sold its operating assets to Dresser Industries.

Coal is transported from the faces by battery-powered ram cars, freedom cars (battery-powered shuttle cars), and a longwall face conveyor. The coal is then transported to the production shaft bottom by belt conveyors, stored in underground bunkers, and hoisted to the surface by skip hoist cars.
This mine used ram dump cars as their shuttle cars. Results showed that coal mine dust exposure is generally very low at the feeder and when tramming. Elevated concentrations are encountered at the ram dump car operator position when the car is being loaded by the continuous miner.
