Hoberstorfer, G; Noren, T

The invention relates to a new, generally applicable method for opening mineral deposits for prospection purposes and for subsequent mining, where necessary ramp systems, drifts or tunnels (developments), which previously were laid in dead rock, now entirely or substantially entirely are laid in the ore. The method further renders it possible, that the deposit can be predeveloped, i.e. that within the deposit different ore grades such as ore types and/or contents are exposed and made immediately and continuously accessible in such a manner, that the subsequent mining at every given occasion can be adjusted and controlled in the desired direction, whereby an adjustment to the market outlook can be made which is at optimum under the prevailing business situation. The method, therefore, must not only be regarded as a new method, which during the prospection phase of a deposit reduces the venture risk and during the subsequent mining maximizes the income, but also as an entirely new mining strategy, because the method produces ore, i.e. economically mined deposits of mineralizations which previously did not economically justify mining.
