| Abstract_FL | The water chemical characteristics of thin limestone karst water in the Taiyuan Formation and thick Ordovician or Cambrian thick limestone karst water in the main coal seam floor of Carboniferous-Permian karst coal field in North China are naturally similar.This similarity poses a risk of misjudgment or even miscalculation when relying solely on certain hydrochemical indexes.Objectives The water quality in-dexes of limestone water,L2 limestone water,and some L7 limestone water are similar,making accurate iden-tification challenging.To address this issue,Methods a neural network model for identifying water sources based on water level,temperature,quantity,and quality was proposed.Taking the filling water source identifi-cation of the Pingdingshan mining area as an example,a 15-10-6 neural network model was constructed with 15 indexes as identification factors,including the anion and cation percentages in milligram equiva-lents,the ratio of sodium to calcium,the ratio of alkali to hardness,ρ(CO2-3),ρ(SO2-4),TDS,ρ(Na+K),water level,dynamic change,water temperature,water intrusion,and attenuation days.Results The experimental re-sults showed that the mean value of all training samples'fitting to their own water sources exceeded 0.98,which significantly improved the recognition accuracy compared with the modeling method that simply took water quality index as the recognition factor,and could completely and effectively eliminate the misjudg-ment caused by similar water quality indexes but different water sources.Conclusions The proposed model-ing method had been incorporated into the computer software and mobile app software for identifying water sources in the Pingdingshan mining area.After testing,the recognition accuracy reached 91.3%. |
