After 25 years of declines in coal workers' pneumoconiosis (thanks to federal regulation of tolerable concentrations of coal dust and radiographic surveillance of miners), CWP and progressive massive fibrosis have been on the upswing since 2001, killing or disabling dozens of relatively young miners.
