Thoresby Colliery has been equipped with the latest Trolex Sentro 8 gas and environmental monitoring system and a Trolex Sentrum methane drainage monitoring system. At Thoresby, the environmental or eModules used are for detecting CH4, O2 and CO in two ranges from 0 – 50 ppm and 0 – 500 ppm. The coal mine is also using remote or rModules with an output of 0.4 to 2V for remote sensors. The Sentrum system is used for methane drainage pipe monitoring to measure methane purity. This methane is then used in power turbines for the mine’s consumption or providing energy for export onto the grid. The mine may also sell on methane in the future to other companies. The accurate continuous monitoring of methane composition by Trolex Sentrum is crucial for the plant to perform satisfactorily. (more…)
