Two deadly mine accidents struck in a single day in eastern Ukraine on July 29. A methane explosion claimed the lives of 17 miners in the Luhansk region, where nine miners are still under the rubble caused by the explosion.
Just hours later, a collapsed elevator in the Bazhana mine in the Donetsk region resulted in the deaths of four people, according to the Ukrainian Emergency Situations Ministry. Seven mine workers were still missing.
Ukraine's coal mines are considered among the most dangerous in the world. They are poorly financed and take only rudimentary safety precautions. Most accidents are caused by methane explosions. According to miners unions, each ton of coal costs the lives of four miners.
The Sukhodilsk Skhidna mine, where the July 29 methane explosion occurred, is operated by the Krasnodonvuhillia company, which belongs to Renat Akhmetov, Ukraine's richest man.
