IMPORTANT FEATURES INCORPORATED ON 3612 MARIETTA DRUM MINER
New generation rugged planetary cutterhead drive providing low speed and high torque, thus helping reduce dust and chance of methane ignition.
Patented canted-end cutterhead for coreless cutting and maximum sumping. Simplified maintenance - Quick change cutter drums without loss of lubricant.
Reliable wet, multi-disc type clutches utilized in the gathering/ conveyor drive and dry multi-disc type clutchesutilized in the cutterhead drive.
4. Arm type gathering system.
5. DC tram drive system
6. 7. 8.
NMS high output area lighting system. Stecko hose fittings for quick changeout of hydraulic or water hoses and components.
Water deluge fire and dust suppression when required.
9. JSAMT scrubber as an option.
10. 11.
12.
Rugged, 36"hi'gh chassis. ,
Floating or fixed operator's pit with or without canopy. Canopy meets MSHAspecificatioris.
Adustable safety prop for the conveyor and cutter booms so they can be worked under safely while in a raised position.
'SAFETY PRECAUTIONSI
1. The machine should not be operated until the operator has read and understood the operating instructions for the machine and is thoroughly familiar with the location, operation and functions of all controls.
2. An operator should not operate the machine without all covers and/or guards properly mounted and secured.
3. The operator should familiarize himself with the fire suppression system of the machine.
4. Always be sure all personnel are clear of machine before starting machine.
5. Carefully test all functions before operating the machine.
6. Always wear safety glasses not,only for your own safety but for that of your fellow workers. Should an operator be temporarily blinded by dust, etc., while operating the machine, the machine becomes a hazard to both men and other equipment.
7. When operating the machine, always keep all parts of your body within the confines of the operator's pit. Hanging head, arms or legs outside the pit could result in severe injury or death.
8. Take extra caution to keep from cutting the cable against the rib or under the track.
9. Any damaged, broken or malfunctioning parts should 'be reported at once to the section foreman.
10. A permissible electrical enclosure should never be opened by anyone except properly trained maintenance personnel.
11. The operator should never try to troubleshoot the cause of a circuit breaker trip, whether the breaker is on the machine or at the power center. Notify proper maintenance personnel to the cause and correct.
12. Never work under a raised cutter boom, conveyor boom or gathering head unless they are properly supported.
RECOMMENDED STEPS TO FOLLOW WHEN OPERATING THE 3612 MINER (Individual mines may require different cycles of operation.)
STEP
OPERATING PROCEDURE
1. Make sure that everyone is clear of the machine and all valves, breakers and switches are in the or off position.
2. Make sure proper voltage is being supplied to the machine.
3 Make sure water is' being supplied to the machine.
4. Turn on main circuit breaker.
5. Turn on control circuit breakers.
6. Turn on area lights.
7. Select and turn on control valve for directional water spray.
8. Turn on headlights.
9. Start pump motor.
10. Raise or lower conveyor and cutter boom for adequate clearance 'and visibility.
11. Put gathering head in float position. For maximum cleanup efficiency, the gathering head should rest against the mine floor and be free to float.
12. Tram machine to the face until cutterhead just touches face.
13. Position the rear conveyor over the shuttle car by raising and swinging to desired position.
14. Raise the cutter boom to the desired cutting height.
15. Start the gathering head/conveyor motor.
16. Activate water spray system.
17. Start cutterhead motors.
18. Lower stabilizer shoe to help stabilize machine during sumping and shearing operation, if required.
19. Sump the cutter head into the face by pushing tram levers forward. Tram machine forward until it has advanced approximately 30" into the top of face.
20. Lower cutting head down, thus shearing the face. Do not tram during the shearing cycle.
21. When head has reached bottom, release shear switch, raise stabilizer shoe and tram machine backward approximately 3''', thus trimming ridges and"smoothing bott.om. '. Make certain shuttlecar is clear before backing miner.
22. Raise the cutterheadand repeat cycle (19 thru 22) until desired amount of face has been cut.
23. Turning crosscuts is accomplished by making a series of partial cuts until the machine can be turned to the de'sired angle.
