Alex Ovechkin, along with several Russian National Team teammates and Russian Hockey Federation officials, joined a social media campaign to support the victims of a recent mining disaster in Siberia.

The campaign is being carried out under the Russian hashtags #МирныйМыСТобой (“We’re with you, Mirny”) and #МирныйМыВместе (“Mirny We’re Together”).

4 августа на алмазном руднике «Мир» в городе Мирный произошло затопление шахты, в которой на тот момент находился 151 человек. Спасателям удалось поднять на поверхность 143 горняков, но 8 еще находятся в заточении. Игроки сборных команд России Александр Овечкин, Егор Коршков, Андрей Алтыбармакян и президент Федерации хоккея России Владислав Третьяк присоединились к акции в поддержку шахтеров и их семей. Мирный, мы с тобой! #мирныймывместе #мирныймыстобой

The caption to Hockey Russia’s Instagram post reads as follows:

On August 4, at the Mir Diamond Mine in the City of Mirny, a flood occurred in one of the mine shafts where 151 people were working. Rescue workers were able to bring 143 miners to the surface, but eight more remain trapped. [Russian] National Team players Alexander Ovechkin, Egor Korshkov, and Andrei Altybarmakyan, as well as Russian Hockey Federation President Vladislav Tretyak, joined the social media campaign in support of the miners and their families. Mirny, we are with you!

Mirny is a major diamond-mining center in Russia’s remote Yakutia region (also known as the Sakha Republic), located in eastern Siberia. As reported by Reuters, the mine in question is owned by ALROSA, a publicly traded but majority state-owned corporation established in the early 1990s to manage the region’s diamond mining concerns.
