Abstract: Microseism monitoring technique in predication and control on mine water disaster has become an indispensable technical means,and it plays an important role in mine safety production.Microseism monitoring technique is the geophysics method characterized by indirect,nondestructive,real-time and continual,it has been included in Detailed Rules and Regulations for Control in Coal Mine Water (2018 edition).Firstly,application principal of microseism monitoring technique for mine water disaster is analyzed;then,the feasibility and prediction regularity of the detection of groundwater runoff zones,water passages (fissure,fault and collapse column),water bursting channel,grout diffusion and goaf unknown water inrush by using microseism monitoring technique is discussed,besides that,the feasibility of monitoring and predicting mine water disaster actively is analyzed based on the multi-field coupling analysis and mutual verification by the combination of microseismic events produced in the process of artificial disturbance (such as underground drilling water,grouting,mining and so on) and the field theories (such as audio frequency electric perspective,transient electromagnetic,stress field,gas monitoring,drilling cutting,acoustic electromagnetic,seepage,rock damage,etc) is analyzed;finally,the advantages and disadvantages of microseism monitoring technique in the application of prediction and control of mine water disaster are summarized,and according to the current study results,the development tendency of the technique is studied.The results show that the main application and study of microseism monitoring technique in prediction and control in mine water disaster can be summarized as scientific arrangement of monitoring network,optimization for positioning algorithm,reliable analysis of the activity regularities of coal,rock mass and water,implementation of multi-field coupling analysis and study of the precursor regularity of microseismic activity of coal and rock mass.
