For benches over 90ft
Every ton of coal you get from your reserves is money in your pocket. Thanks to ADDCAR highwall mining systems, you can get thousands of additional tons from reserves that would have been abandoned just a few years ago. ADDCAR’s highwall technology is specially designed to maximise the recovery of your reserves which are accessible from the economic limit of your surface operation.
The central module of the ADDCAR Broad Bench system is the launch vehicle. This is the main Broad Bench Highwall Systemstructure of the highwall system, housing the electrical and hydraulic systems, hosting the operator’s compartment and other control functions, launching the miner into the seam and supporting the coal handling systems. First, the launch vehicle is lined up perpendicular to the coal seam at the desired location. A crawler-mounted continuous miner presses into the highwall, cutting the coal and feeding it onto the unique ADDCAR conveyor cars, which are placed at the back of the production line as the miner advances. This method of extending the production string means uninterrupted coal flow. The conveyor cars feed the coal car-to-car without use of an auger, which can increase fines. When it reaches the last conveyor car, the coal dumps off onto a final conveyor, which sends it to a stacking conveyor in back of the vehicle. The miner can drive an entry up to 1,600′ into the wall. Support equipment includes a stacker conveyor and wheel loader with forklift attachment. The deck crew remains under a FOPS canopy; and operators work in climate-controlled compartments.
