(1)In 2015, "Research on Karst Groundwater System and Prevention Water of Laohudong Phosphate Mine in Weng'an County, Guizhou Province" won the first prize of engineering survey results in non-ferrous metal construction industry. The mine has large reserves and high grade, but the problem of water inrush and flooding seriously restricts mine development. The company provides technical support for mine mining through the mode of "survey + design + water prevention research", and the mine has entered the construction stage at present.

⑵ "Evaluation of Hydrogeological Conditions of Duancun-Leigou Bauxite Mine and Research on Water Prevention and Control Technology in Production Stage" completed in 2017 won the second prize of Excellent Engineering Consulting Achievements of China Nonferrous Metals Construction Association. Through the research on the change law of groundwater flow field in recent years, the project team has constructed a groundwater numerical model with higher simulation degree, and simulated the characteristics of groundwater flow field in different mining conditions and periods, which is of great significance for guiding the water prevention and control work in various production stages of mines.
