The method comprises drilling and blasting ore in a bench (19) of ore within the mine pit and collecting ore blasted from the bench from a floor (5) of the mine pit using at least one mobile excavation machine (11). The method also comprises delivering ore that has been collected by the mobile excavation machine to at least one mobile-in-pit crusher (41), and transporting crushed ore to outside the pit on at least one ladder conveyor (23) that extends up the wall of the pit.
Description
Technical field
The present invention relates to exploit the ore that comprises precious metal.
But the present invention exclusively relates to the exploitation iron ore particularly anything but.
Background technology
Traditional strip mining transformation of iron ore comprises: the boring and the part of explosion ore body progressively make and can pick up ore by forklift or other excavator that is fit to, and ore is transmitted from the hole on haulage truck.The a series of steps of known use are exploited the iron ore of bulk, make it possible to carry out simultaneously in the hole multiple recovery activity.At first to the pattern of step boring with formation " explosion " hole, described step can be that for example 40-200m is long, 20-100m is dark and 10-15m is high, and comprises ore and/or other material of thousands of metric tons.For example analyze the material that is removed during the process of shot hole getting out by chemical analysis, with determine on average whether ore is that (a) is high-grade, (b) inferior grade or (c) waste material.Boundary between the upper-lower hierarchy depends on series of factors, and can change between the mine and in the different piece at mine.The explosive that use is prepared in the bulk goods preparation truck of particular design comes the step of explosion ore, this explosive is normally based on ANFO (ammonium nitrate/fuel oil), and this bulk goods preparation truck can adjust the density of explosive before loading shot hole downwards.The material that explosion goes out is picked up with the native vehicle of moving of excavator form, and this excavator for example is cord forklift, diesel oil hydraulic crawler excavator or front-end loader, and the material that goes out of explosion is placed in the haulage vehicle such as truck, and sends away from the pit.Determine ore is handled outside the pit according to grade.For example, abandoned mine is used as mine fills, and low grade ore is stored or is used for mixing with high-grade ore, and high-grade ore further handled as required, to form vendible product.
