 THE DEPTH OF THE SHAFT IS 159m.
 5 HEADING DEVELOPMENT IS DONE.
 THE WIDTH AND HEIGHT OF THE GALLERIES IS
6mX4.6m.
 THE DIMENSIONS OF THE PILLAR IS 32mX32mX4.6m.
 DEGREE OF GASSINESS-II

Actually Continuous Miner is a package of machinery including-
Coal Cutting Machine :- Continuous Miner
Coal Hauling Machine :- Shuttle Car
Coal Lump Breaking & Feeding
Machine to Conveyors :- Feeder Breaker
Face Supporting Machine :- Quadbolter
Face & Road Cleaning Machine :- LHD
Power Distribution :- Load Centre
As Continuous Miner is large underground machinery, so lowering the
package of CM machinery can only be done through incline of proper cross
section & gradient – not through any shaft / pit.
OPERATING MACHINERIES

Typical Development Layout
The standard layout consists of a five road development, with the main conveyor and feeder breaker
positioned in the central roadway. This provides working areas to carry out all the main development
functions:
One heading for the CM to be
cutting
One heading ready for cutting
One heading for ventilation
rearrangement and survey work
One heading for cleaning by
LHD
One heading for supporting by
Quadbolter

SPOOLING MECHANISM

 Boom lifting mechanism is present so to adjust with variable
discharge heights.
 Telescopic type of cylinder is used.
 Atmospheric vent is provided in the cylinder to prevent the
cylinder from damage during roof fall condition.
extend pressure: 120.6-127.5 bar.
atmosphere relief pressure: 227.7 bar.
 Dual output pump is used 46 lpm and 34lpm.
 The high volume stage of pump delivers (46LPM) fluid to
cable reel valve(Since here, shuttle car is in stationary mode,
cable reel motor will be in stalled position) & conveyor
elevating cylinder.
 The Low volume Stage delivers (34LPM) fluid to hydraulic
cylinders in steering mechanism and Brake circuits
(emergency/ park & service).

 FOUR WHEEL STEERING MECHANISM IS USED IN JOY
SHUTTLE CARS TO NEGOTIATE TIGHTER TURNS.

 Four floor jack cylinders are provided at four
corners of the shuttle car so that the machine
can be lifted from the ground for maintenance.
