Abstract

Longwall mining is one of the most acclaimed and widely used in underground method for coal extraction characterized with high production, productivity and safety potentials. The interaction of powered roof supports with the roof is the key issue in strata mechanics of longwall mining. Longwall coal extraction method though showed the potential of high outputs, never rose to the expectation in India due to factors pertaining to strata mechanics problems, poor spares management, adaptation of technology without suitability analysis and unyielding exertion ethnicity. The paper attempts to discuss the role of different strata monitoring instruments installation, working principle and data monitoring procedures’ in powered support longwall system in India and effective scientific tool to predict various aspects related to strata mechanics of such workings. Load density, height of caving block, distance of fractured zone ahead of the face, overhang of goaf and mechanical strength of the debris above and below the support base have been found to influence the magnitude of load on supports.
