Abstract

The article gives a brief description of geology of Oleniy Ruchey deposit and the characteristic of current mining situation in Oleniy Ruchey Mine, Northwestern Phosphorus Company. The limitations of the current scheme used to open up the ore body with ore drawing via vertical blind skip-hoist shaft and conveyor tunnel are discussed. The new-developed rational schemes for opening-up and mining, taking into account stagewise commissioning of the Mine, are compared from the viewpoint of economic performance. The authors point out benefits of stagewise opening-up of Oleniy Ruchey ore body by inclined conveyor shafts.
