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
maximize 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
 structure
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. |
