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.

Telegram has gained a reputation as the “secure” communications app in the post-Soviet states, but whenever you make choices about your digital security, it’s important to start by asking yourself, “What exactly am I securing? And who am I securing it from?” These questions should inform your decisions about whether you are using the right tool or platform for your digital security needs. Telegram is certainly not the most secure messaging app on the market right now. Its security model requires users to place a great deal of trust in Telegram’s ability to protect user data. For some users, this may be good enough for now. For others, it may be wiser to move to a different platform for certain kinds of high-risk communications. What distinguishes the app from competitors is its use of what's known as channels: Public or private feeds of photos and videos that can be set up by one person or an organization. The channels have become popular with on-the-ground journalists, aid workers and Ukrainian President Volodymyr Zelenskyy, who broadcasts on a Telegram channel. The channels can be followed by an unlimited number of people. Unlike Facebook, Twitter and other popular social networks, there is no advertising on Telegram and the flow of information is not driven by an algorithm. Oleksandra Matviichuk, a Kyiv-based lawyer and head of the Center for Civil Liberties, called Durov’s position "very weak," and urged concrete improvements. Telegram was co-founded by Pavel and Nikolai Durov, the brothers who had previously created VKontakte. VK is Russia’s equivalent of Facebook, a social network used for public and private messaging, audio and video sharing as well as online gaming. In January, SimpleWeb reported that VK was Russia’s fourth most-visited website, after Yandex, YouTube and Google’s Russian-language homepage. In 2016, Forbes’ Michael Solomon described Pavel Durov (pictured, below) as the “Mark Zuckerberg of Russia.” On December 23rd, 2020, Pavel Durov posted to his channel that the company would need to start generating revenue. In early 2021, he added that any advertising on the platform would not use user data for targeting, and that it would be focused on “large one-to-many channels.” He pledged that ads would be “non-intrusive” and that most users would simply not notice any change.
