The blast struck the Wujek-Slask mine on Friday morning, a spokeswoman for Poland's mines authority, Edyta Tomaszewska, told reporters.
She said 30 miners were taken to hospital. The blast occurred 1,050m (nearly 3,500ft) underground.
The miners were working more than a kilometre underground at the time.
Several of the injured have sustained severe burns, and medical staff have warned the death toll may rise.
