Miner's Revolution

A whole Furnace colony gone, oxygen cut off and food rotten. Four years ago, you and a communications group of 14 set up radios throughout seven different Furnaces without the Elites knowing. A few weeks after the completion of those seven radios, one of the miners told yours and other Furnaces that their oxygen and food supplies were decreasing every day, and they couldn't do anything about it. A few weeks later, you lost contact. They were dead. A whole Furnace colony of 214 people suffocated all because they didn't mine enough Emberstone. 3 years later, the revolution is really starting to make an impact. And you are leading it. Any tips and feedback are appreciated since this is only my second scenario.
