25. DISCRIPTION
RAJNAGAR 5/6 MINE IS A UNDERGROUND MINE AND THE SEAM IN WHICH THE
DEVELOPMENT AS WELL AS DEPILLARING METHOD IS GOING ON. RAJNAGAR MINE WAS STARTED ON
MARCH 1976 AND AT THE TIME OF SURVEY ITS AGE IS ESTIMATED 35 YEAR . BUT THE PRODUCTION
FROM THE 5 & 6 MINE IS STILL IN PROGRESS. RAJNAGAR 5/6 MINE IS 9KM FROM BIJURI RAILWAY
STATION. RAJNAGAR 5/6 MINE IS IN SHALLOW DEPTH . SO THE INCLINE OPENING METHOD IS
ADOPTED. IN THE INCLINE OPENING THERE IS TWO PATH ONE FOR THE IN AND OUT OF MAN POWER
WHICH IS CONNECTED TO THE INCLINE AND THE SECOND IS THE INCLINE ITSELF WHERE THE
TRANSPORTATION OF MATERIAL TAKE PLACE WITH THE HELP OF HAULAGE TRACLINE MADE FOR
MATERIAL TRANSPORTATION . THE TRANSPORTATION OF MATERIAL INCLUDE HEAVY MACHINERY i.e.
SAND ,BRICK , WIRE, etc. WHICH ARE USEFUL AND VALUABLE FOR THE MINE . THE TRANSPORTATION
ARE DONE WITH THE TUBS . THE TUBS USED FOR THE TRANSPORTATION ARE OPERATED BY THE ROPE
WHICH PULL THE TUBS BY THE ELECTRICALLY OPERATED MOTER ON WHICH THE ROPE IS WOUNDED
IN A ROUND . IN THE RAJNAGAR 5/6 MINE WHEN WE ENTER INSIDE THE MINE THEN THE FLOOR THE
SEAM AT THE RIGHT SIDE OF THE HAULAGE THERE IS A PUMP ON WHICH ALL THE WATER OF THE MINE
IS STORED AND THEIR IT IS PUMPED OUT . IF WE PROCEED FURTHER IN STRATED WAY THEN THE
HAULAGE IS DIVIDED INTO TWO PATH RIGHT PROCEED TO THE DEVELOPMENT AND LEFT TO THE
DEPILLARING FACE. AT THE DEVELOPMENT SIDE THE DEVELOPMENT PROCESS IS IN PROGRESS BY
DRILLING AND BLASTING METHOD.IN ADDITION TO THAT THE CONSTRUCTION OF HAULAGE AS WELL
AS SUPPORT AND OTHER ELECTRICAL CONNECTION ARE DONE . THE TRANSPORTATION OF THE COAL
IS DONE WITH THE HELP OF SIDE DISCHARGE LOADER (SDL) IN WHICH THE COAL IS LOADED AND
DISCHARGED TO THE TUBS FROM WHERE IT IS TAKEN TO THE TIPPLER WITH THE HELP OF ROPE OR
DIRECTLY TRANSPORTED TO THE CONVEYOR BELT FROM IT IS TAKEN TO THE SURFACE AND LOADED
TO THE TRUCKS AND TRANSPORTED TO MAIN VEHICLE i.e. RAILWAY TUBS FROM WHERE IT IS TAKEN BY
THE POWERPLANT.
