Mechanized cut and fill mining refers to cut and fill stopes that are accessible byrubber tired equipment from the regular mine access development. Mechanized cut and fillstopes can be very productive with stope widths in excess of 40 m in good ground
Dry rock fill is rock waste surface sands gravels or dried tailings. The fill iseither dropped down a raise or tipped into an open stope by a Load Haul Dump LHD ordump trucks. Dry rock fill is most suited for the cut and fill mining method.
This method can be used in wider deposits as well by drilling two adjacent access rampsand cutting two adjacent drifts often called drift and fill sources: Mining Know-How .Cut and fill is for hard rock as it doesn& 39;t feature the support mechanisms inherent
Mining Method - Cut and Fill: Capacity - 2000 tpd: Turmalina Deposit. The Turmalinadeposits are lo ed in the western part of the Iron Quadrangle which was the principalregion for Brazilian hard rock gold mining until 1983 and accounted for approximately 40%
This is the independent spam and off-topic free Forum for all persons who are working inthe Mining Industry or have an interest in Mining.
The three principal mining methods are: Mechanised ramp and fill both overhand andunderhand 80 – 90% Sub-level extraction by long hole open stoping with hydraulicbackfilling 10 – 15% Overhand cut and fill C and F stoping utilising either
Cut and Fill mining is a method of short hole mining used in narrow ore zones.An accessramp is driven off the main level to the bottom of the ore zone to be accessed. Usingdevelopment mining techniques a drift is driven through the ore to the defined limit of
This type of mining is typically done upwards from lower levels so the fill is also usedto provide a new working level for further mining. Cut and fill mining can be expensivebut this method allows for highly selective mining with less waste rock or low-grade ores
Backfilling with controlled specifi ions is employed for improved ground support andpillar recovery in underground metalliferous mine workings. This paper reports theresults of a laboratory study to characterise various mechanical properties of cemented

Cut-and-fill - A method of stoping in which ore is removed in slices or lifts and thenthe excavation is filled with rock or other waste material backfill before thesubsequent slice is extracted. Cut value - Applies to assays that have been reduced to
