MONITORING THE OPERATIONAL PARAMETERS OF A POWER ROOF SUPPORT
Journal Title: Journal of Machine Construction and Maintenance - Year 2018, Vol 109, Issue 2
Abstract
Safety aspects of mining personnel as well as the safety of the coal mining processes are presented. A mechanised longwall system is commonly used in the coal mining industry. The system consists of the basic machinery, such as a shear loader, an armoured face conveyor, and a powered roof support, which protects the roof of workings. The powered roof support consists of hydraulically or electro-hydraulically controlled units, equipped with pressure sensors placed in different parts of the hydraulic system and displacement sensors for the selected actuators. Projects related to the automation of roof support operation and the monitoring of its parameters are currently being undertaken.Analysis of available solutions concerning the controlling and monitoring of the roof support with special regard to pressure measurement in a prop and roof support geometry measurement is presented. Existing solutions are describedand KOMAG development directions for parameter monitoring systems of roof support operation in terms of personnel and technical safety are indicated. The paper discusses work realised within the framework of PRASS III “Productivity and safety of shield support” project, co-financed by Research Fund for Coal and Steel (RFCS).
