Water-solution mining is the main mining method of salt mines currently.During the mining process,a large number of solution cavities are formed in the salt layers.Identifying the development of solution cavities and the extent of damage to the salt roof is important for guiding the design of production wells,utilizing the space of salt cavities,and guaranteeing the safe production of salt mines.In order to accurately and finely portray the morphology,scope,size and upper solution development of the cavity,a high-precision 3D seismic exploration cavity fine portrayal imaging technology has been formed through the study of the observing system applicable to cavity detection,cavity fine imaging processing,multi-attribute comprehensive interpretation and cavity 3D geologic modeling.Engineering application shows that this technology can accurately explore and portray the development direction,development situation,internal connection situation,and the degree of roof damage,etc.,and provide technical support for the planning and arrangement of mining wells in mining areas and the management of mine safety and production.
