Core Viewpoint - The project team from China Aluminum International Engineering Corporation has achieved a significant technical breakthrough in a hydrological geological survey project for a large lead-zinc mine in Baoshan, Yunnan, which has been stalled for over a decade due to complex hydrological conditions [1][5]. Group 1: Project Overview - The mine has a resource reserve of 1.02 million tons of lead and zinc, indicating high development value [5]. - Previous assessments indicated high water inflow and strong water-conducting faults, leading to a complex hydrological situation that hindered development [5]. - The cost for water prevention and control engineering was estimated at 200 million yuan, which contributed to the long-term suspension of safety facility construction and mining design [5]. Group 2: Technical Innovations - The team developed an innovative "integrated air-ground, pumping verification, and three-dimensional simulation" exploration technology system, which downgraded the hydrological conditions from "complex" to "moderate" [1][10]. - High-precision hydrological geological mapping was conducted to clarify underground water circulation patterns, utilizing advanced geophysical techniques to accurately depict the distribution of underground water-bearing structures [5][7]. - A large-scale group well pumping test was implemented, with dynamic monitoring using high-precision sensors, improving data collection accuracy by over 50% compared to traditional methods [5][7]. Group 3: Results and Implications - The new exploration conclusions overturned previous judgments, indicating weak water-conducting faults and minimal hydraulic connection between surface and groundwater, significantly reducing hydrological risks [10]. - This breakthrough allows for the resumption of safety facilities and mining design, effectively resolving the decade-long "water prison" dilemma [10]. - The innovative approach not only clears obstacles for the mine's development but also provides a replicable model for data-driven decision-making in the mining sector, revitalizing dormant mineral resources [10].
