The current state of the mining industry is characterized by a tendency to rapid deepening of mining, which leads to an increase in the mineral excavation self-cost and negatively affects the safety of production. The effectiveness of an underground geotechnology largely depends on the correct choice of methods and schemes for ore and rock transportation, which is becoming increasingly important, with deepening mining. Currently, the most common transports in underground mining are rail and road vehicles; mine hau...

A tough requirement for the development of the Partomchorr apatite-nepheline ore deposit containing rare-earth elements is a performance of environmental safety of production, because a sanitary zone of the projected mining and processing plant sides with the boundaries of the existing Simbozersky nature reserve and the created Khibiny national park. The studies have substantiated reasonability of the Partomchorr deposit development by a combined mining method; in the first stage step-by-step mining of four open p...
