Introduction. The Russian opencast mineral mining industry pro-duces more than 90% of iron ore, 70% of nonferrous metals and 60% of coal. Production output mostly grows in large opencast mines, which, naturally, governs the increase in their depth and size. The cost of mineral hau-lage reaches 60% of total opencast mining expenditures.
