At least one person died in the second mining accident in Poland within a few days.

Nine other miners are still missing after the earthquake in the Zofiowka coal mine in the south of the country, as the mine operator JSW announced on Sunday.

Only on Wednesday at least five people died in a methane explosion in a mine also operated by JSW in Pniowek, southern Poland, and seven more are still missing.

On Saturday, the rescue workers managed to locate four of the miners buried in the Zofiowka mine.

According to JSW, rescue workers managed to rescue one of the workers.

A doctor was only able to determine the man's death, the operating company said.

There is no contact with the three other missing persons who have already been localized JSW Notice.

According to the operating company, the earthquake in the Zofiowka mine occurred on Saturday night at around 3:40 a.m. at a depth of 900 meters.

As a result, methane gas escaped from the mine.

42 of the 52 miners who were underground at the time of the accident were able to return to the surface unharmed.

The Zofiowka mine was already the scene of a mining accident in 2018.

At that time, five miners died after an earthquake in the mine.

Almost 80,000 people work in Poland's mining sector

Poland's Prime Minister Mateusz Morawiecki expressed his dismay at the recent accident on Saturday.

The news about the earthquake in the mine is "devastating," he explains.

The mining accident in Pniowek only shook the people of Poland on Wednesday.

A methane gas explosion occurred in the coal mine at a depth of around a thousand meters shortly after midnight.

A second explosion followed when rescue workers were already at the scene of the accident.

The blasts killed five people, including a rescue worker.

20 other people suffered injuries, some of them serious.

The search for the seven missing people was called off after another detonation on Friday.

JSW boss Tomasz Cudny called it "irresponsible" to continue the deployment of rescue workers.

Poland still gets about 70 percent of its energy from coal.

Almost 80,000 people work in the country's mining sector.

A number of mining accidents have occurred in the country in recent years.

Last year, two men died and two others were injured when a wall collapsed underground in the Myslowice-Wesola mine in southern Poland.
