For the analysis of Wolong Lake 8101 working face water inrush source and water collection,statistics of the mine groundwater samples of conventional water quality analysis data of 62groups were collected.Using a combination of models and multivariate statistical methods combiningmaltab,this paper illustrated the gushing water of 8101 Face.The results show that the water resourceof 8101 consistent with the mine 10 coal sandstone type.The primary factor of Lake Wolong ore stratumof groundwater quality is Ca²⁺，Mg²⁺，SO₄^2- which reflects Taiyuan limestone water supply beingfrom the other water resource;the second factor is the cation exchange adsorption,which embodiesthe static storage consumption of groundwater flow.The method of multivariate statistical modeland maltab is a kind of high stability and effective,which is applicable to discriminate the groundwatersource water chemistry.
