Abstract: Based on geological conditions of Huainan coalfield,including distribution of coal strata and lithologic features,production and testing of seismic geology model of coal measure strata in Huainan are completed.Seismic data acquisition and processing provide clearly the seismic reflection characteristics of the physical model. We designed seismic numerical simulation model of the coal measure strata in Huainan by seismic numerical simulation technology,and analyzed the variation features of seismic responses.The results show that the simulation production of low speed coal seam and fractured zone are key of the seismic physical modeling techniques,at the same time,seismic physical model guides coal seismic exploration,helps to understand characteristics of seismic wave field.Seismic detection can detect cavern,different caverns can cause significantly difference of diffracted wave and seisnic seismic reflection wave field.As the seismic physical modelling experiments at home and abroad are mainly used for oil and gas exploration and development,this technique in the coal fields is rarely used to solve practical problems,therefore,the results of this research is important.
