摘要
矿坑涌水量预测是关系矿山安全生产的研究难点,以利用解析法进行某铁矿涌水量预测为例,结合矿床开发利用方案,阐述矿体产状对开采水平所对应的可采范围水平投影影响以及矿床充水地层水力性质变化等因素对矿坑涌水量预测的影响。研究结果表明:解析法公式众多,应用相对广泛的是大井法和廊道法,采用"大井法"进行矿坑涌水量预测时,大井范围应是开采水平所对应的该水平可采矿床水平投影,而不是全矿床水平投影。在实际应用中要根据采矿范围和具体开发利用方案,选择合适的方法。
The prediction of mine water inflow is a research difficulty related to mine safety production. Taking the prediction of a certain amount of influx of iron ore by analytical method as an example,combined with the development and utilization scheme of ore deposits,the effect of the ore body shape on the horizontal projection of the recoverable range corresponding to the mining level is described. The results of the study indicate that the analytical method has many formulae,and the big well method and Corridor method are relatively widely used. When the ＂ big well method＂ is used to predict the amount of water in the pit,the range of large well should be the horizontal projection of the horizontal mining bed corresponding to the mining level,instead of the horizontal projection of the whole deposit. In practical applications,the appropriate method should be selected according to the mining scope and the specific development and utilization plan.
