Powered roof support systems are large complex hydraulic machines and are essential to the operation of modern coalfaces. The main aim of the project was to develop methods of monitoring the condition of hydraulic powered support systems. The programme of work included development of techniques, evaluation and field trials. The main areas of work covered were: - pressure deficiency profile; - optical liquid level detector; - mine water pump monitoring; - suction filter blockage; - 60/40 emulsion monitoring; - 5/95 emulsion monitoring; and - pump monitoring. The report details the work undertaken on all the above work areas, the techniques developed and evaluated, and their testing, both in the laboratory and underground. The methods can be used to monitor the condition of powered support systems and the results can be used by engineering management at collieries so that maintenance and corrective action can be taken to remedy problems before failures and delays are caused.
