2019-4-1 · 1. Introduction. Highly mechanized mining processes are widely used in surface mining because they generally provide an efficient approach for achieving high production (Shrestha and Lal, 2011).However, high production is also associated with large volumes of waste production (Ramani, 2012).During surface mining, the excavated materials from depths of 0-200 m are stripped off and Types of Mine Backfill MiningInfo Google Sites,2021-4-1 · Sand obtained from surface borrow pits will be screened prior to use in a backfill plant to remove oversize particles that could plug the backfill line. Sandfill can be cemented or uncemented. Successful sandfills have permeability coefficients in the range of 7x10-8 m/s to 7.8x10-5 m/s corresponding to a medium silt to coarse sand.
