T he 3D hig h density elec tr ical technique is put for war d by changing the layo ut of lines, impr oving t he inst ruments and equipment, dev elo ping the soft war e for data acquisit ion and pr ocessing , realizing the acquisit ion of 3D data bo dy of water enr ichment in floo r of wo rking face befor e mining and the 3D r esist ivity imag ing of the water enr ichment in flo or of w or king face by using slicerdicer softw are as t he plat form to show the wat er enrichment in flo or of w or king face audiov isually through easily hor izontal and vert ical slicing . T he pr act icalit y and v alidity of this technique are ex em plified. Key words:f loo r w ater enrichment; 3D hi
