The optimal number of experimental wells for substantiation of slime sampling methods in open-pit mining of mineral resources

Abstract

Following the results of authors experimental works on Kovdorsky apatite-shtaffelite deposit and taking into account the results of similar works performed by other researchers on ore deposits of various genetic and industrial types, it has been established that for justification of sampling method of slime of drilling-and-blasting wells at open-cast mining of any ore deposits the five experimental wells for each type of a loop of slime (cone-shaped or extended along the «boring machine - mouth of a well» line) are enough.
