摘要:

为有效评估未来矿区水资源供需平衡情况, 需精准预测矿区未来矿井涌水量。根据宝日希勒露天矿现有水文地质及充水条件, 采用水平集水廊道法、大井法、水文地质比拟法以及水均衡法四种方法对2025年矿坑涌水量进行了预测。结果表明: 水平集水廊道法和大井法的水文地质参数选取受人为因素影响较大, 预测结果偏大; 水均衡法仅能根据矿区水均衡资料进行预测, 预测精度不高; 水文比拟法对相似性条件要求较高, 预测精度较精准。最终根据水文比拟法预测结果确定宝日希勒露天矿2025年矿坑涌水预测水量为185.27 万m3/a。模拟分析了矿区采动作用对地下水流场的影响, 模拟结果表明, 工作面采掘潜水水位最大降深值为50m。随着工作面采掘的不断推进, 地下水降落漏斗面积先增大后保持不变。该研究为矿区安全生产、矿区排水设计以及水资源优化配置提供可靠的数据支撑和技术支持。

Abstract:

Based on the "rich coal, poor oil, little gas" resource endowment conditions in China, coal is still the cornerstone of energy security. Abundant mine water generated by coal mining is a precious water resource, which can be used for mining area production and life by effective treatment. Accurate prediction of mine inflow is significant in mine drainage design and water resource proof. Taking Baorixile Surface Mine as an example, the hydrogeology and water filling conditions of the mine area are analyzed, and the mine inflow under the production condition in the future (2025) is predicted by using the hydrologic analogy method. Based on the relevant datas of the mine from 2001 to 2019, the multiple regression equation of the mine inflow and other related factors is established.The results show that the hydrologic analogy method has high prediction accuracy and is feasible. Finally, the predicted miner inflow value of Baorixile Surface Mine under the future production condition is 6375.02m3/d.The study provides reliable data support and technical support for safety production, drainage design and optimal allocation of water resources in mining areas.
