【摘要】 矿山给水排水是矿床采选工程安全、顺利生产的基本保障条件之一,在给排水系统相对独立的中小型矿山,矿坑涌水往往是生产用水的重要水源。在这类给排水系统设计中,矿坑涌水量预测,不仅关系到矿床开采生产安全和矿山给水安全,而且关系到矿山与周边环境之间的水交换。以江苏省沛县姜梨园铁矿为例,基于矿坑涌水量预测开展矿山给排水系统研究,以求在充分利用矿坑涌水资源的前提下,为生产给水安全和合理排水规模设计,提供技术依据。姜梨园铁矿是一水文地质条件复杂的小型铁矿,古生代碳酸盐岩裂隙岩溶水和上覆新生界松散孔隙水,构成矿床的直接充水水源。在现有的勘查成果的基础上,结合矿山巷道开采设计方案,建立水文地质概念模型和相应的地下水流数值模拟模型;利用数值模拟模型,对矿山开采条件下的矿坑涌水量及其变化过程进行预测、评价;将矿坑涌水量及其变化过程与矿山开发利用的合理用水量相结合,确定在正常工况条件给水与配水方案、非正常工况条件下的排水方式与规模。鉴于矿坑涌水量预测存在较大的不确定性,在分析并确定影响矿坑涌水量的主要水文地质参数的基础上,依据勘察中的相关成果,利用MC算法计算参数分布频率,结合数值模拟模型的预测结果,评价矿坑涌水量预测值的风险率,为第二水源设计提供依据。更多还原

【Abstract】 Mine supply and drainage water is one of the basic security conditions for deposit mining engineering for safe and smooth production. For water supply and drainage systems in small and medium sized independent mining,pit flow is often an important source of production water.For drainage system in such a design, prediction mine water, has not only relationship between the production of safe deposit exploitation and mining water safety, but also relationship to the mining and water exchange between the surrounding environment.Take the Jiang Liyuan iron ore(Pei Country, Jiangsu Province)for example,based on mine water system to carry out mine drainage and mine with a view to making full use of the premise of water resources,technical basis is provided for the production of drainage water supply safety and reasonable size of the design.Jiang Liyuan iron ore is a complex hydrogeological conditions of small iron ore,Paleozoic Carbonate karst fissure water ,pore water overlying Mesozoic and Cenozoic loose,form a direct deposit filling water.Based on the current survey results and the combination of mine tunnel exploitation of design, hydrogeological conceptual model and the corresponding numerical simulation model of groundwater flow were established;using numerical simulation model,on the conditions of the mining mine water and the change process were predicted and evaluated;Mine water and the change process were combined with the rational development and utilization of mine water,and water supply and water distribution programs were determined to normal operating conditions,the scale of the drainage way. was determined to non-normal operation conditions.In view of mine water there is a big uncertainty in the analysis and determination.Based on analyzing and determining hydrogeological parameters and according to the related survey results,MC algorithm was used to calculate frequency distribution of parameters,combining with the numerical simulation model prediction, evaluating the risk of mine water,and the basis was provided for the design of the second water source.更多还原
