Mining Management Plan NTEPA

2016-7-1  The proposed mining method is a room & pillar-style underground mining from the existing decline and proposed new development. Dewatering of the existing workings will be required to re-gain access to the mine. Mined ore will be hauled to the existing Toms Gully processing facility which is rated at 250,000 dry tonnes per annum (tpa).

The Actual Difference Between Surface and Underground

Surface mining is suitable for large, low-grade ore deposits which occur below a thin layer of rock, or alluvial deposits found in sand and riverbeds. Underground mining is used for small, high-grade deposits covered with a thick overburden (soil and rock above the ore), or for

Types of Mine Backfill MiningInfo

2021-8-5  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.
