Continuous dust monitoring in headings in underground

The chart presents two production cycles related with cutting of coal with a heading machine. During mining with a heading machine, the instantaneous values of concentration of the respirable fraction measured with an optical dust sampler exceeded the measurement limit of the device. It means that at least 50 mg/m 3 of dust was in the air.
