The Integrity of Continuous Miner and Personal Dust Samples

This project describes an extensive programme of ‘shadowing’ and monitoring of continuous miner and personal dust samples in production sections of an underground colliery over a three month period. One third of all respirable dust samples, both continuous miner and personal samples, have been shown to be unreliable. The main causes of unreliable samples were in the preparation, issuing, receiving, and wearing of dust pumps.
