In the long-term mining practice of multiple mines in the Binchang mining area,the differences in vertical hydro-geological conditions of the extra-thick Luohe formation aquifer have gradually emerged.In the past,the Luohe formation was regarded as a unified aquifer or simply divided into layers,which can no longer meet the current needs of water hazard pre-vention and control work.Therefore,it is necessary to conduct a detailed exploration of the hydrogeological conditions of the Luohe formation aquifer,study its vertical differences in water abundance and internal control factors,and carry out a de-tailed division of its layers.Based on geological research,this paper comprehensively applies geological data such as drill-ing,logging,logging record,core analysis and testing,regional data,and stratification data to evaluate and study the vertical and horizontal distribution characteristics of the sandstone water-bearing medium in the Luohe formation of the Yadian Coal Mine in the Binchang Mining Area,providing a basis for the precise division of the Luohe formation.
