| 中文摘要: |
| 矿坑涌水量预测是矿床水文地质勘探的重要组成部分,分析矿区地下水水流系统的演变规律,有助于加深对矿区地质条件和水文地质条件的认识,判明矿坑充水水源及其途径。文章在分析姜梨园铁矿区地质、水文地质条件的基础上,重点分析了F1断层的水文地质特征,确定了矿坑排水条件下含水层组间的水力联系,建立了水文地质概念模型及相应的数学模型、数值模型,借助Visual MODFLOW软件,在进行模型识别与验证后,结合矿山开采方案,预测了矿床的正常涌水量与最大涌水量。 |
| 英文摘要: |
| The forecasting of water inflow of pit is the important component of the mine hydro-geology exploration. Analyzing the evolution of mining area groundwater flow system will be benefit to the recognition of the mining geological and hydro-geological conditions, and to identify the sources and conduit of pit water filling. On the basis of detailed analysis of the geological and hydro-geological conditions of Jiangliyuan mining area, authors focused analyzing the hydro-geological characteristics of fault F1, and ensured the hydraulic connections among aquifers under the conditions of pit drainage. Then they built the hydro-geological conceptual models and the corresponding mathematical models and numerical models. After model identification and verification and combining with mining program, they predicted normal and the maximum water inflow of pit with Visual MODFLOW software. |
