Abstract
In order to maintain the sustainable development of mine and learn the characteristics of Lower group coal resources,a study was conducted on the Ordovician limestone aquifer,which is the strongest potential water source affecting the mining of lower coal.In this study,the hydrogeological conditions of 100 m below the top interface of Ordovician ash were studied through drilling,pumping tests,sampling and testing.It was found that the Ordovician limestone aquifer has obvious hetero-geneity and vertical zoning,the karst development in the Ordovician limestone aquifer is general,locally good,with moderate to strong water richness,and the main types of water quality are HCO3-Ca and HCO3-Ca·Mg,which can provide hydrogeolog-ical basis for the future mining of Lower group coal resources.关键词
