Accoding to the shallow depth mine pressure burmp danger area.statc loading igh concentration.no roof activity pressure bump danger features, basedon Gushan Mine as an engieeing backgrcund.the paper theoreticaly determined the types of the mine pressure bump o.cured and pointed out the main leading roleof the concentrated static loading. Aastep by step evaluation ,step by step disersion and combined inspection wereconduced on the concentrated staticleading with he seismic cCT 'technology.numerical simulation.site measuremert and other nethods.The resuits showe that the concentrated loading was provided by the roof of the shallow depth single layer magmatic rock.the mine pressure bump case was occure with no dynanicloadig souces pariciared and th mornioing ofthe mine ressure bunmp would be the static loading mainly.Before the mining operation conducted.,the seismic CT delecion resutis showed that afer the mine pressure bunp occurrd,the high concentrated area of the statcloading would be existed sti. During the mining proc.ess the realtime monioring of the static lading coul oe ftted with the high mine pressure bump danger area revealed by the numeical simulaton. The dynanicloading information proided by the micro seismic and earth sound was appliedto inspect the monitoring results of the statcloading. The foor and sean fracturing were caused by thecoal mining face pushing forwar.the disclapse rof and highconcentrated static loading.
