Investigation of sudden faults instability induced by coal mining
Published 2019“…© 2019 Elsevier Ltd Study on the mechanism of coal burst induced by faults instability is a major concern for the safety mining and efficient production in the underground coal mine. In this paper, the sharp change of roof bolt loading, roof separation, roadway deformation and mining face support stress were observed during the routine field tests. …”

Seismic inversion for Geotechnical properties relevant to coal mining
Published 2008“…The 3D seismic reflection method has an established role in Australia in mapping geological structures, faults and discontinuities that might affect the operation of an underground coal mine. However, successful longwall mining also requires knowledge of geotechnical properties of the roof and floor strata. …”

In situ monitoring of primary roofbolts at underground coal mines in the USA
Published 2014“…To mitigate this concern a study was conducted in 2010 by the National Institute of Occupational Safety and Health, in conjunction with Southern Illinois University of Carbondale, to assess the performance of primary roofbolts in underground coal mines for improved safety and cost. This was accomplished using underground roofbolt monitoring solutions, field data, and numerical modelling to better understand the quasi-static behaviour of underground coal mine roofs and the response behaviour of the bolts.In particular, over 170 instrumented extensometers, closure meters, shear meters, fully-grouted passive rebar, fully-grouted tension rebar, and resin-assisted mechanical roofbolts were installed at three coal mines across the USA. …”
