2、ents increasingCoal mines are in complex hydro-geological conditionsExtension of coal mining depthCoal demand constantly increasingPrevention of coal water-inrush are renewed attentionINTRODUCTIONCoal mine water hazard cognizanceIs a complex and adaptive phenomenonPossess nonlinear dynamic character

3、isticsPrevention methods of coal water-inrushWater bursting coefficient 、Vulnerability index methodCritical layer analysis、Fault tree analysisGIS、DC、TEM & Information fusion analysisINTRODUCTIONDeficiency of the traditional methodFailed to describe the nonlinear dynamic phenomenaNot studied on the v

4、iew of system scienceThe creative points of the thesis Solving bycomplex systems theory &methods Using Agent-based modeling and simulation(ABMS)EVOLUTIONARY ModelFormation mechanism of coal water-inrushWater-inrush principle & Energy accidental release & Human error theoryEVOLUTIONARY ModelEvolution

5、 mechanism of coal water-inrush Water Channel Drainage and emergency measures. Mining activitiesEVOLUTIONARY ModelAgent-based model of coal water-inrushAgents interactive in the model. SIMULATION ProcessesSimulation platform : NetLogoParameters settingWater sources rank : 0-5Channel permeability : 0

6、-1Mining activity: #workers*NDrainage ability: base on water volumeIterations:5000SIMULATION ProcessesSimulation interfaces in NetLogoTwo dimensional area is divided into four parts: water area、channel area、mining activity area & drainage area. Change parameters will simulate different situations.SI

7、MULATION ResultsCurve Explaincurve water-richness of the mine;curve intercepting effect of water-proof layer. curve risk levels of water in mining areas. curve drainage ability of the mining area. SIMULATION ResultsSimulation situation ExplainSafety mining conditionA better conditions of water proof

8、 layer SIMULATION ResultsSimulation situation ExplainWater-proof layer is damaged suddenly Low drainage abilitySIMULATION ResultsSimulation situation ExplainWater plugging technology is usingDrainage ability is improvedCONCLUSIONSUsing ABMS to study the evolution of coal mine water hazards is adoptingEvolution process is dynamically presentedRes
