Multi-factor dynamic analysis of the deformation of a coal bunker in a coal preparation plant

Abstract To assess the deformation of a coal bunker and propose effective preventative measures for such, real-time monitoring system was designed. Moreover, methods were proposed coal-bunker inclination, settlement, groundwater level, temperature, material level. By using vector autoregression model time-series data deformation, long-term equilibrium relationship derived between inclination settlement their influencing factors. The dynamic effects each factor on how contribution changes revealed by an impulse response function variance decomposition. results show that vary hysteretically. Groundwater level has constant small negative temperature continuous significant effects; however, positive slightly influences eastward while significantly northward bunker. Also, unbalanced loading little influence but its inclination. Therefore, should be strengthened in summer, sudden avoided during production. can adjusted reverse direction.
