The 21 miners went overground on Monday evening, Polish state news agency PAP reported.
They had been demanding that the new coal industry law be extended to cover their company.
The new law entails protective measures for miners at publicly-owned mining companies that close their mines.
The agreement on job security for PG Silesia miners was signed on Monday afternoon in the regional capital Katowice.
The talks had been held under the Tripartite Team for the Social Security of Miners, with the participation of Energy Minister Miłosz Motyka.
Under the agreement, if the PG Silesia mine goes bankrupt, the government will allocate new jobs to its workers at other coal mines.
At the same time, the owners of PG Silesia declared they would continue to run the mine as part of a lease arrangement.
The government also pledged to revise the coal industry law to expand protective measures available to miners, putting privately-owned PG Silesia on an equal footing with state-owned mines.
The agreement was signed between trade unions at PG Silesia, the government represented by Motyka, Bumech - the owners of PG Silesia - and the mine's court-appointed receiver.
Bumech confirmed it was ready to rent PG Silesia assets and take on all of its employees in line with labour law.
The court-appointed receiver said that no miners would be made redundant and that no disciplinary action would be taken against the protesting miners.
The trade unions promised to end the protest and not take similar action until the renting deal is finalised.
The government, which mediated between the miners and PG Silesia, said it would take steps to work out legislative measures by the end of February to guarantee protective measures and alternative jobs to PG Silesia miners if the company running the mine went bankrupt.

Following the deal, Motyka said the government was taking social dialogue seriously and thanked all those taking part in the talks.
"For us, dialogue is not a slogan, but, as I hope we showed, it is practice that leads to an effective compromise for the good of the people," the energy minister told reporters.
