Today, the diamond mining sector, both in Russia and worldwide faces a number of problems, which are the consequences of longyear deposit development and ever growing requirements to environmental safety. The problem of resource shortage is also ever growing. Nearly all kimberlite pipes with high diamond concentrations have been depleted already by the surface mining method, which is the most efficient and cost-effective technique. Underground mining of the remaining reserves of rich pipes can be profitable so far, while pipes with by far lower diamond concentrations are loss-making for underground mining. It is particularly true for diamond deposits of Yakutia, where due to unfavorable geological conditions and climate operators have to use underground mining methods with consolidating stowing.

Key words: diamond mining sector, underground mining, deposits of Yakutia, profitability, environmental safety, advancing roof support of simple design.
