摘要
根据矿区具备多处位置、水平不同的生产坑道和含水层富水性弱等实际情况。利用生产坑道的排水资料,选择比拟法、曲线方程法,对砖庙硼矿区花园沟矿段进行了矿坑涌水量预测,取得了较好的效果。通过矿段的开采实际验证、对相邻类似矿段生产坑道的回访调查认为:对于含水层富水性弱,具备生产坑道的老矿区,充分利用生产坑道排水资料,选择切合实际的计算方法,建立非确定性统计模型,预测矿坑涌水量,方法正确,结果准确,在矿坑涌水量预测中具有实际应用价值。
The productive galleries at various positions and levels in Zhuanmiao mining district are characteristic of having aquifers of low water-richness. On the basis of this fact, the existing data about the water-drainage of the galleries are applied successfully to prognosis of the water gushing volume of the pits with the aid of the methods of selective comparison and curve equation. It is believed through the experimental validation of ore blocks under mining and the back-check of similar productive galleries that full use of gallery water-drainage record, selection of practical calculation methods and establishment of qualitative mathematic models to forecast pit gushing prove a hydrogeologic practice of application value with correct thought and exact results, particularly for old mines having productive galleries of low water-richness aquifers.
