  2. 2.  AN INTRODUCTION TO SARPI PROJECT. VARIOUS MACHINERIES DEPLOYED IN THEMINE. DEVELOPMENT AND DEPILLARINGPATTERN FOLLOWED IN THE MINE. COST OF THE CONTINUOUS MINERPACKAGE. SHUTTLE CAR:a) SPECIFICATIONSb) VARIOUS MECHANICAL AND HYDRAULICSYSTEMS IN A SHUTTLE CAR.c) SAFETY FEATURES.
  3. 3.  BORD AND PILLAR TYPE OF MINING IS FOLLOWED. MINE IS STILL IS IN DEVELOPMENT PHASE. CONTINUOUS MINER IS USED FOR CUTTING THECOAL INSTEAD OF CONVENTIONAL DRILLINGBLASTING METHOD. DAILY PRODUCTION OF THE CONTINUOUS MINERPANEL IS ABOUT 1500 TONNES. THE DEPTH OF THE SHAFT IS 159m. 5 HEADING DEVELOPMENT IS DONE. THE WIDTH AND HEIGHT OF THE GALLERIES IS6mX4.6m. THE DIMENSIONS OF THE PILLAR IS 32mX32mX4.6m. DEGREE OF GASSINESS-II
  4. 4. Actually Continuous Miner is a package of machinery including-Coal Cutting Machine :- Continuous MinerCoal Hauling Machine :- Shuttle CarCoal Lump Breaking & FeedingMachine to Conveyors :- Feeder BreakerFace Supporting Machine :- QuadbolterFace & Road Cleaning Machine :- LHDPower Distribution :- Load CentreAs Continuous Miner is large underground machinery, so lowering thepackage of CM machinery can only be done through incline of proper crosssection & gradient – not through any shaft / pit.OPERATING MACHINERIES
  5. 5. Typical Development LayoutThe standard layout consists of a five road development, with the main conveyor and feeder breakerpositioned in the central roadway. This provides working areas to carry out all the main developmentfunctions:One heading for the CM to becuttingOne heading ready for cuttingOne heading for ventilationrearrangement and survey workOne heading for cleaning byLHDOne heading for supporting byQuadbolter
