We present the articles of the first issue of scientific journal "Mining Science and Technology" (Russia) for 2025:
Scientists have analyzed energy efficiency of mining operations, focusing on ventilation fans and hoisting machines as the most energy-intensive equipment. The study examines main ventilation fans and hoisting systems at Molibden mine, proposing optimization measures to improve efficiency and reduce costs. Research methods included analytical approaches for ventilation system evaluation. Findings show inefficient fan operation with excessive energy use, suggesting motor replacement could save 4.9 million rubles annually. Analysis of hoisting equipment recommends modern multi-rope systems for better performance. Data reveals inverse correlation between productivity and energy use - 10–15% output increase reduces energy consumption by 2–5%. Implementing automated controls and optimizing equipment utilization can significantly enhance efficiency. These results are applicable to other deep mining operations.

In February 2014, the Ukrainian people ousted pro-Russian president Viktor Yanukovych, prompting Russia to invade and annex the Crimean peninsula. By the start of April, Pavel Durov had given his notice, with TechCrunch saying at the time that the CEO had resisted pressure to suppress pages criticizing the Russian government. The news also helped traders look past another report showing decades-high inflation and shake off some of the volatility from recent sessions. The Bureau of Labor Statistics' February Consumer Price Index (CPI) this week showed another surge in prices even before Russia escalated its attacks in Ukraine. The headline CPI — soaring 7.9% over last year — underscored the sticky inflationary pressures reverberating across the U.S. economy, with everything from groceries to rents and airline fares getting more expensive for everyday consumers. Founder Pavel Durov says tech is meant to set you free To that end, when files are actively downloading, a new icon now appears in the Search bar that users can tap to view and manage downloads, pause and resume all downloads or just individual items, and select one to increase its priority or view it in a chat. That hurt tech stocks. For the past few weeks, the 10-year yield has traded between 1.72% and 2%, as traders moved into the bond for safety when Russia headlines were ugly—and out of it when headlines improved. Now, the yield is touching its pandemic-era high. If the yield breaks above that level, that could signal that it’s on a sustainable path higher. Higher long-dated bond yields make future profits less valuable—and many tech companies are valued on the basis of profits forecast for many years in the future.
