Discrimination Research Of Water Inrush Source Of Roadway In Dagushan Iron Mine Based On Analysis Of Hydrochemical Characteristics

The progress and development of human society are inseparable from mineral resources.The development and utilization of mineral resources are directly related to the sustainable development of the national economy and society.Since the twentieth century,The manufacturing industry shows an explosive growth trend.The large-scale industrial production and manufacturing has continuously increased the demand for the quantity and variety of metal minerals,which has promoted the exploration and mining of various metal minerals.A large number of metal deposits have been explored and quickly put into production,which meets the needs of industrial production to a certain extent.While developing and using metal deposits,some problems have gradually emerged.In the construction and production of metal mines and mines,especially in the excavation and support of roadways,water inrush is often accompanied.The water inrush is extremely harmful,which poses a great threat to the life safety of mine workers,At the same time it will also bring huge economic and property losses.Dagushan Iron Mine is an important iron ore production base in China.The quality and quantity of iron ore production affects the speed of China's socialist modernization process to a certain extent.But the water inrush problem in the side lane of Dagushan open-pit iron mine greatly affects the normal and efficient production of Dagushan iron mine.Therefore,Through detailed understanding of the current status of the roadway inrush in the Dagushan Iron Mine,the relationship between groundwater replenishment and drainage in the surrounding area of the Dagushan Iron Mine,and then the hydrogeological and environmental geological conditions of the Dagushan Iron Mine,and the source of the inrush water,And finally put forward reasonable preventive measures to solve the water inrush problem of the side lane transportation roadway in Dagushan Iron Mine.This article combines existing literature data,through hydrogeological survey,hydrogeological field test and indoor test,groundwater dynamic observation and other methods to study and analyze the hydrogeological profile,the hydrochemical characteristics of surface water and groundwater,the rules of hydrochemical evolution and the characteristics of hydrogen and oxygen isotopes near the Dagushan Iron Mine Source of gushing water.The results show that there are a series of fractured water-conducting structures near the water inrush point of the northwest transportation lane of Dagushan Iron Mine,which provides good conditions for the occurrence of groundwater and runoff.The results of hydrochemical analysis showed that the water chemistry characteristics of the water in the tunnel were the same as those of the underground water in the Xiejiafangshen Village in the northwest of the mine and the Dagushan Village in the west of the mine.Combined with the results of multivariate statistical analysis and pumping tests,it can be determined that the water inflow of No.2 roadway is mainly bedrock fissure water in the area of Xiejiafangshen Village in the northwest of the pit,and the water inrush of No.3 roadway is the fourth in the area of Dagushan Village in the west of the pit.
