Abstract:
Water inrush and drainage not only pose a threat to the safe operation of mines but also lead to water resource waste and pollution of other water bodies.Thus, implementing water-preserved mining holds significant practical implications for the sustainable development of mines.Therefore, this paper firstly analyzes the hydrogeological conditions of Xinzhen Mine, clarifying the aquifers, aquitards, and their hydrogeological and engineering geological conditions.Based on an analysis of the impact of mining activities on aquifers, a water-preserved mining plan for Xinzhen Mine is formulated from two aspects: water-preserved mining methods and mine water resource utilization.Finally, a comprehensive analysis of the water-preserved mining plan for Xinzhen Mine is conducted in terms of technology, economics, environment, and social benefits.The results show that: fissure water is the primary target for mine water resource protection; goaf areas within the mining area and adjacent goaf areas are the key prevention and control targets; and the water-preserved coal mining plan that combines the establishment of water-resistant coal pillars, water-filled water preservation, drainage diversion, and mine water resource utilization is reasonable and feasible.
