The document provides information about Akhilesh Kumar's summer training project at South Eastern Coal Field Limited's Gevra project in Chhattisgarh, India. It discusses Coal India Limited, the largest coal producer in India. It then describes the Gevra project, the largest open cast mine in Asia. The project involved studying heavy earth moving machines like dumpers, shovels, drills, and dozers used at the mine. Information about various machines, their specifications and functions is presented. The annual coal production for 2012-2013 is reported and plans to increase production capacity for 2013-2014 through larger machines are mentioned.

3. PROJECT UNDERTAKEN:- BASIC STUDIES OF HEMM (HEAVY EARTH MOVING
MACHINES) DEPLOYED IN A COAL MINES.
THERE WERE FOUR DEPARTMENT. NAMELY,
EXCAVATION WORKSHOP SHOVEL SECTION
DRILLING SECTION DOZER SECTION

4. EXCAVATION WORKSHOP
THIS WAS FURTHER SUB-DIVIDED INTO THREE SECTIONS
DUMPER SECTION TYRE SECTION
GRADER AND CRANE SECTION

5. DUMPER SETION

CUMMINS ENGINE PRODUCING 733 hp.
• IC DIESEL, 4 STROKE, TURBOCHARGED
COOLED, DIRECT INJECTION, WATER
COOLED ENGINE.
• THEY ARE AIR START ENGINE & NEED 135
psi OF PRESSURE.
• THERE ARE AUTOMOTIC LUBRICATION
SYSTEM.
• THREE TYPES OF BRAKE
1. SERVICE BRAKE
2. PARKING BRAKE
3. RETARDER BRAKE

9. KOMATSU 785-7- 100Te DUMPER

10. CAT 777D- 100Te DUMPER

11. CAT-793D- 240Te DUMPER

CONTAINS 5 ECM’S AT ENGINE, BRAKE,
HYDRAULIC SYSTEM, CHASIS AND
TRANSMISSION.
• BRAKES ARE EITHER HYDRAULIC OR
NUMETIC.

12. TYRE SECTION
• THESE BEARS ALL THE LOAD OF DUMPER.
• 34% LOAD TO FRONT AND REST 66% TO
THE REAR TYRES.
• THER ARE OF TWO TYPES
1. RADIAL TYRES
2. CROSS-PLY TYRES
• AIR FILLED INSIDE SHOULD BE MOISTURE
FREE AND RIM SHOULD BE CLEAN AND
PAINTED.
• NITROGEN IS FILLED INSIDE THE TYRE AS
IT IS COOLING GAS AND INCREASES THE
LIFE OF THE TYRE.
• TEMPERATURE INCREASES UPTO 60 °C IN
WORKING CONDITION.
• LIFE OF TYRE IS CALCULATED IN TERMS
OF TKPH.

13. CRANES AND GRADER SECTION
