The labourers were working thousands of feet down in the deep mine when the poisonous gas leaked and accumulated, suffocating the labourers to death, Dawn News said.
The incident happened in Sanjidi coal mine located some 45 km away from the provincial capital of Quetta.
The injured labourers were shifted to a nearby hospital where they were said to be in critical condition.
Coal mines in the province are notorious for their unsafe working conditions.
Accidents often happen in the mines as labourers are not provided with modern equipment to ensure their safety.
Earlier in April this year, four labourers were killed in another coal mine in Quetta when the mine they were working in caved in.
