The first accident occurred in Marwaarh, 45 kilometres east of Quetta, which is the capital of oil and gas-rich Balochistan province, due to a gas explosion.
Six people were rescued and taken to a hospital for treatment, and rescuers were still looking Saturday night for one person believed trapped in the mine, officials said.
The roof of the mine caved in following the explosion triggered by the accumulation of methane gas, killing 16 miners and wounding nine others, two of them seriously, according to Jawaid Shahwani, the top government official in Quetta. There were 30 workers inside the mine at the time of the accident. "We have recovered all the 16 bodies from the rubble caused by the collapse in the coal mine", Atique said.
Seven miners were killed after a mine collapsed in similar circumstances at Spin Carez.

The resolution said those found guilty of negligence be awarded punishments, mines where such fatal incidents took place be sealed and laws pertaining to safety of miners be implemented.
The Pakistan Central Mines Labor Federation told the BBC that an average of 200 miners die in mine disasters every year.
They said lack of safety arrangements inside the two mines, including air ventilation, had caused the fatal incidents.
