Planning for the development of room and pillar mines operates in much the same way as other mining methods, [10] and begins with establishing ownership of the mine. . Following this, the geology of the mine must be analysed, as this will determine factors like the lifespan of the mine, the production requirements, and the cost to develop and
A mass haul diagram where land and rock cuts are hauled to fills Fill construction in 1909 Cut & Fill Software showing cut areas highlighted in red and fill areas shaded in blue. In earthmoving , cut and fill is the process of constructing a railway , road or canal whereby the amount of material from cuts roughly matches the amount of fill ...
Cut and fill mining is an expensive but selective method, with the advantages of low ore loss and dilution. [4] Drift and fill is similar to cut and fill, except that it is used in ore zones, which are wider than the method of drifting will allow to be mined. In this case, the first drift is developed in the ore, and is backfilled using ...
The word is also used in the same sense in mining, in particular Open-pit mining. The use of cuttings often provides byproducts as a form of mineral extraction , commonly sand, clay or gravel; the cost of building drains, reinforcing banks against landslide and a high water table are factors which commonly limit its use in certain areas.
Hydraulic fill is likely to be the most economic method of construction. Even when the source material lacks sufficient elevation, it can be elevated to the sluice by a dredge pump. In the construction of a hydraulic fill dam, the edges of the dam are defined by low embankments or dykes which are built upward as the fill progresses. The sluices ...
In shrinkage stoping, mining proceeds from the bottom upwards, in horizontal slices (similar to cut and fill mining), with the broken ore being left in place for miners to work from. Because blasted rock takes up a greater volume than in situ rock (due to swell factor ), some of the blasted ore (approximately 40%) must be removed to provide ...
