The textbooked definition of cut and fill activities is a process of earth moving, whereby the ideal amount of material cut from an area roughly matches the amount of area that needs to be filled. Earthworks can be a very costly process, so will always be favorable to have limited import or exporting of fill.
cut and fill mining Cut and fill mining the ore is excavated by drilling and blasting in horizontal slices, starting from the bottom of a stope and advancing upwards as in shrinkage stoping. A slice has a thickness of not more than 3 m.
Cut is defined as removing material to lower the elevation of an area. Fill is defined as placing material to raise the elevation of an area. Compaction must take place during a fill operation to increase the density of the soil material being placed. Another common breakdown in excavation work is bulk excavation and trench excavation.
4 Depend on cut material, contractor should suggest the requirement for crashing plant and if more soil required from outside the site or if the cut is more than fill to be transferred outside the site. 5 Defining the best economic hauling distance for each cut/fill for .
As a mining method cut and fill is ideally suited to the extraction of ore from narrow steeply dipping orebodies, from orebodies with irregular contacts or outlines, from orebodies with poor or low strength wall rock, and for pillar recovery. The majority of the production from cut and fill mining .
Read the Text Version. The underhand method under consolidated fill ensures a high recovery under an engineered backthat is comprised of cemented rock fill and/or cemented paste fill. This method of mining is generally necessary eitherdue to a weak rock mass comprising the immediate back and/or high induced back stresses.

The proposed method is of value to earthwork managers because it identifies the most favorable EAP by accounting for the rockearth type of each and every prism, the series of prisms occupying each and every cut and fill pits, and the moving directions (, the order of cutfill prism pairs), expeditiously.
Cut and fill. This method consists of blasting the ore by successive horizontal lift and extracting from the stope all the ore as the breaking occurs. The mucking of the ore is done with a scraper or loader towards a chute, generally developed in the backfill.
Excavation and embankment (cut and fill) Excavation = the removal of soil or rock from its natural location. ... Pyramid Method If one end area has a value of zero, the earthwork volume can be considered a pyramid and the correct formula would be: Volume cut/fill Formulas Legend required
Oct 02, 2019· A cut and fill is a procedure at construction sites to level slopes and create cuttings, canals, and embankments by removing earth from one point and using it as a fill in another. Techniques for this procedure have several distinct benefits, the most attractive of which are the time and cost savings the process offers.
Mechanised Cut and Fill. This is the classic method for mining narrow orebodies and involves extracting the ore in small slices, 2 to 4m high, working from the bottom upwards. As each cut is extracted, the void is filled, primarily to form a working platform for the next lift.
Cut and Fill. We are experienced in cut and fill engineering, where excavated material (cut) is used to raise the level of other on site areas (fill). Following our cut and fill operation the subsoil is usually decompacted prior to spreading and levelling the topsoil layer and installing a .
Jan 21, 2008· The cut/fill quantities calculated by LDD (assuming you created a stratum between existing ground surface and a finished ground surface) should not be your final cut/fill quantities that you supply to the Owner. Items such as topsoil removal replacement and road pavement sections need to be calculated and integrated into your earthwork numbers.
Standard mining techniques include: cut and fill or drift and fill; ore is mined and the stope filled with tailings, raising the level of the mining. shrinkage stoping – similar to cut and fill except the ore is blasted and left in place and used as a mining platform.
In fact, you could even replace the phrase, "cut and fill calculations," with the phrase "excavation and embankment calculations." Excavation is the "cut" portion of the phrase, where we determine how much soil and rock needs to be removed from a plot of land.
Underground mining with the cut and fill method has been declining during the past decade or so, being replaced mostly by sublevel open stoping methods.
