Engineering properties of marine clays from the eastern coast of India

  The paper deals with the engineering properties of a marine clay collected from Visakhapatnam, India. First of all, the physical, chemical and mineralogical properties were determined. Thereafter, the strength and stiffness of the soil-water matrix were established. The properties under cyclic stress reversal were also studied. The detailed test results and observations are discussed sequentially in the...

Rock cutting with surface miner: A computational approach

  Surface miner is proved to be an efficient rock excavation technique in surface mines. However, till date, mining industry is facing a problem in selecting best surface miner model suitable to their conditions amongst the models available in the market. The readily available models are purchased by the mine authority and then, are deployed in the mines. This results into the increase in mining cost and...
