| Description |
A number of surface miners are being used in Indian mines and construction sites and represent a majority of their global population. The market is growing for these little marvels as several researchers are investigating their application in varied rock mass conditions. Small changes in intact rock and rock mass parameters can adversely affect the performance of mechanical excavators. Therefore, proper planning is required for the selection of surface miner of a desired specification under given geo-mining, intact rock and rock mass conditions. An approach for selection of suitable surface miner has been discussed in this paper. A study has been conducted on the performance of several models of surface miners deployed in Indian coal and limestone mines with special reference to rock properties. A range of rock properties are assessed and analysed with machine performance. Rock cuttability index (RCI) has been developed by taking into consideration all the critical parameters influencing machine performance. A nomogram has been framed for representing the rock cuttability index and production performance estimation. The study involves a comprehensive methodology for the selection of a suitable surface miner, through nomogram, by combining the relevant influencing parameters, namely, intact rock, rock mass, machine desired production.
