On this day, 28 years ago, on December 2, 1997 (November 3, 1997 in the lunar calendar), a gas explosion occurred in the Zeryanovsk mine in Russia. On December 2, 1997, a gas explosion occurred in the Zeryanovsk mine in Novi Kunetsk, Russia, killing 67 miners. Russian scientists believe that the explosion was caused by land tides caused by the moon's gravity causing changes in the earth's crust. Russian scientists pointed out that the tidal phenomenon caused by the lunar gravity occurs not only in the ocean, but also on land, but the magnitude is small and difficult to detect. When the moon, earth, and sun are aligned (i.e., full moon or new moon), the tides on land and ocean are strongest. When the tidal wave on land is large, it will cause a huge pressure difference in the crust and rock layers. If a place is located in a natural fold or fault zone, or the bottom layer is deformed due to human reasons (such as mines, reservoirs, etc.), this tidal phenomenon will cause huge Rock pressure may cause earthquakes, deep crust explosions, mountain impacts, etc. Before such a disaster occurs, a large amount of methane, radon and other gases will be released in the rock formation, and a plasma zone will also be formed. Russian scientists said the explosion actually occurred at midnight on December 1, one day after the new moon. It may have been caused by a local earthquake caused by the gravity of the moon. They believe that due to the increasing number of human factors causing stratigraphic changes, humans must consider the possible consequences and take preventive measures when developing and utilizing natural resources.
