  Krupp Industries India - Detlev L. Schroeder - Krupp Foedertechnik, Germany ABSTRACT The opencast method used for mining hard coal and rocks requires drilling and blasting of strata which causes considerable investments and also creates an adverse impact on the environment & safety. These disadvantages demand the introduction of improved technology for blasting free, safe, eco-friendly and economic mining. By continuous research and also experience gained from the rock cutting technology with the application of road header etc. it has become possible to do mining without blasting by a continuous surface miner for hard coal and rocks. Krupp Födertechnik, Germany has developed Krupp Surface Miner (KSM 2000) which can work in medium-hard and hard coal and also in overburden very efficiently up to 40 MPa and in special cases like small lenses and/or thin layers up to 120 MPa of compressive strength. The article has been written with a special focus to Krupp Surface Miner (KSM 200...

  INTRODUCTION OF DSI SNAKE HIGH ANGLE CONVEYOR TECHNOLOGY: Cost of truck haulage from mine pits are high and spiraling with inflation, diesel price, increasing haul distances and depths. Trucks, traditionally, have long been a favorite tool in surface mines for hauling material from the pits. The increasing strain of an inflationary economy has caused mine operators to look at alternatives to the longstanding workhorses (trucks) in material haulage. The intent of any major modification of the time-honored material handling by trucks is to achieve the goal of a marked reduction in haulage costs; sufficient not only to recoup the capital investment, but to make the final product more competitive in today's world market. Due to increasing cost of truck haulage, now In-pit crushing and belt conveyor systems are one prominent alternative that has gained popularity. The favorable economics of conveyor based haulage, especially in moving large volumes, has long been acknowledged. This ha...
