Turkey's Disaster and Emergency Management, or AFAD, said that rescuers reached bodies of Maoshun Yang and Shouje Sun in the mine, near Tarlaağzı village, 14 kilometres to Amasra town of the Black Sea province of Bartin.

Earlier on Saturday, Shouping Sun was rescued by his co-workers and was carried to hospital. No further information has been released on his condition.

Amasra Governor Kadir Yener Eser said that the accident occurred while they were engaged in fortification work in a gallery. 

According to an official document, the mine was ordered by state labor inspectors to stop operations on September 25 after it failed to pass an official inspection due to deficiencies that could prove life-threatening.

The report on the inspection said that the mine was ordered to shut down because of deficiencies or lack of certification in four critical areas: rescue stations, rescue teams, general ventilation, and electrical equipment used in the works.

An official from HEMA, a Black Sea region energy industry company running the mine, said they regularly train the staff about labor safety, and that the latest training session was as early as Friday.

Company officials have yet to comment on the failed inspection in September.

The incident took place at the coal mine near Tarlaağzı village, 14 kilometres to Amasra town of Bartın province.

The initial reports said that three workers of Chinese origin have been trapped underground when the mine collapsed during the mining activities.

One of the miners, trapped inside, was found dead by the miners while another one was rescued after injuring on his body, according to officials.

Turkey's NTV news channel quoted Bartın governor Seyfettin Azizoğlu as saying one of the trapped miners has been rescued by a group of miners after being injured in the collapse.

The injured miner, 40, was hospitalized by the paramedics after receiving a provincial care on the site.

Search-and-rescue efforts have continued for third miner, still believed to remained inside the mine.
