Intelligent optical fiber sensor systems may help reduce the number of mining disasters.

Tongyu Liu, Shandong Micro-Sensor Photonics Ltd., and Eric Bergles and William Yang, BaySpec Inc.

According to the latest official mining statistics, from 2003 to 2006, more than 20,000 people died from coal mining accidents in China. Death tolls are at levels of four persons per billion tons mined per year compared with the US level of 0.04. As a result, a mine safety program in China is turning to fiber sensing technologies to gauge gases, to detect mine shaft collapses and more. Previously, digital methane-monitoring systems were used to sense gases, but they suffer from cross-sensitivity and from small dynamic range, and they require recalibration every one to two weeks. For mine...Read full article
