中文摘要:
      矿井涌水量数值预测的精度与虚拟疏放孔布设的位置与时间密切相关,为提高矿井涌水量预测的精度,本文以蔚州矿区某矿井为例,建立基于GIS多源信息的奥灰含水层富水性分区评价模型,并将该分区评价结果导入到涌水量数值模型当中,根据矿井工作面的采掘衔接计划,通过在强富水区分阶段布设虚拟疏放孔,从而预测出研究区涌水量的动态结果。实例应用表明:该方法提高了矿井涌水量预测的精度与实用性,对有效制订矿井疏排水方案,保障矿井安全生产具有重要的理论指导意义和实用价值。
英文摘要:
      The accuracy of numerical prediction of mine water inflow is closely related to the position and time of virtual drainage hole layout. To improve the accuracy of mine water inflow prediction, taking a mine of Yuxian mining area as an example, an evaluation model of Ordovician limestone aquifer based on GIS multi-source information was established, and the evaluation result was integrated into the numerical model of water inflow. Then, according to the mining plan of the working face, the dynamic results of water inflow in the study area were predicted by laying virtual drainage holes in high water abundance zones in stages. Example application shows that this method improves the accuracy and practicability of mine water inflow prediction, and has an important theoretical guiding significance and practical value for effectively formulating mine drainage scheme and guaranteeing mine safety production.
