Mine stockpile design to minimise environmental impact

2014-5-15  Keywords: quality control, decision support, mining, stockpile design, intelligent stacking/reclaiming, forecasting, simulation. 1 Introduction Iron ore from inland mines is railed to port, where it is crushed, separated into lump and fines products and stored onto large stockpiles. Ships are loaded for export with ore reclaimed from the stockpiles.

Ore pass practice in Canadian mines SAIMM

2009-8-26  Ontario mines favor steep ore passes (80º ± 8.3º) in an effort to ensure continuous material flow and limit hang-up occurrences. A statistical analysis, however, can obscure site specific practice. In one particular mine, operating in depth and using multiple ore passes, the average inclination was greater than 87º. Ore pass section shape

For example, if for the same mined ore tonnage, a block model produces more metal than an alternative, then the former model is more selective than the latter.

Ore Pass Mining Fundamentals

2014-5-24  An ore pass is a vertical or near-vertical opening, which is created during underground mining operations to transfer materials. It is designed based on the gravitational force between different ground levels, in order to provide a convenient material handling system and reduce haulage distances.

Mining Blasthole stoping Britannica

Mining Mining Blasthole stoping: When the dip of a deposit is steep (greater than about 55°), ore and waste strong, ore boundaries regular, and the deposit relatively thick, a system called blasthole stoping is used. A drift is driven along the bottom of the ore body, and this is eventually enlarged into the shape of a trough. At the end of the trough, a raise is driven to the drilling
