Mine safety

Authorities on Wednesday detained four people in connection with a massive landslide that engulfed a gold mine in eastern Turkey, leaving at least nine workers missing, Turkish state media reported.

The presence of methane gas and lack of adequate supervision were some of the reasons behind the unfortunate mine blast in which 42 workers lost their lives in the northern province of Bartın's Amasra district, says a report by the parliamentary commission established to investigate the incident.

Three of the miners who lost their lives in the mine explosion in the Black Sea province of Bartın were close friends and started working at the mine on the same day three years ago, daily Hürriyet has reported.

Among 41 miners who died in the explosion, Okan Akgül, Şaban Yıldırım, both 27 years of age, and Mehmet Bulut, 31, worked the same shift in the mine.

More than 50 people were reported to have died on Nov. 25 after smoke filled a Siberian coal mine and a rescue effort ended in tragedy.

Senior managers at the mine in Russia's Kemerovo region had been detained for suspected safety violations, after the latest deadly accident to hit the country's vast mining industry.

Rescuers worked overnight into Saturday searching for around 300 people missing after a dam collapse at a mine in southeast Brazil killed at least nine, but the local governor said "odds are minimal" that they would be found alive.

A local court has ruled that a mine's owner and a state institution pay 395,000 Turkish Liras to the family of a miner who was one of the 301 miners killed in an 2014 accident in a coal mine in the Aegean district of Soma in 2014. 

Two miners have died due to carbon dioxide poisoning at an unlicensed mining facility in Turkey?s Black Sea province of Zonguldak. 

Erol Gün and Ahmet ?en, who were working at an unlicensed coal mining facility in Zonguldak, died as a result of carbon dioxide poisoning on Aug. 31. 

An expert report has found that the company that operated the coal mine in the Aegean town of Soma is 100 percent responsible for last year's mining accident, in which 301 workers were killed.

An official expert report on the deadly mine accident in the Ermenek town in the Central Anatolian province of Karaman has proven that the disaster was not natural, but caused by technical neglect, while also citing that miners were poorly trained.

Main opposition Republican People's Party (CHP) leader Kemal Kılıçdaroğlu said safe rooms should be compulsory in mines and subcontracting must end in Turkey's mining sector, as he attended the Dec. 5 funerals of five miners who died after being trapped in a coal mine in the Central Anatolian town of Ermenek.
