About

Jijie Cheng is a leading researcher in deep coal mining geomechanics, specializing in the stability and support of fully mechanized roadways. His work addresses one of the most pressing safety challenges in underground mining: the catastrophic failure of deep roadway supports. Cheng’s major contribution is the development of a novel method for determining the working resistance of advance support brackets, a critical parameter for preventing roof collapses in high-stress, deep environments. Using Flac3D numerical modeling, he demonstrated a breakthrough advance support scheme that combines self-moving hydraulic supports with an anchor-cable unit, significantly improving roadway stability. His most-cited paper (8 citations) provides the theoretical and practical framework for this integrated support system, offering a safer alternative for deep coal extraction. Cheng’s research is directly impacting mine safety engineering, providing actionable design criteria for support brackets that can withstand the extreme pressures of deep mining. His work is essential reading for mining engineers and researchers focused on geotechnical stability, ground control, and the safe exploitation of deep coal resources.
