合山煤田矿井涌水量的数值模拟探讨

矿井涌水问题一直是困扰煤矿安全生产的重大问题之一.如何准确的预测煤矿井下涌水量一直是国内外专家、学者、工程技术人员都在努力探求的问题,尤其对于地质条件复杂的煤矿井下涌水量的预测评价更为突出.本文在充分认识和掌握了研究区水文地质条件、含水介质的空间结构,建立了与实际情况相符合的数学模型,重点研究了模型的边界条件、模型的时间和空间离散、含水介质的水文地质参数的确定,制定了预测模型的检验标准,并运用目前较为流行的地下水数值模拟软件Visual Modflow对研究区进行了长达30年的井下涌水量数值模拟,得出了比较合理的各矿各阶段的井下涌水量.

DISCUSSION SIMULATION FOR THE MINE DISCHARGE OF HESHAN COALFIELD

Problem of the mine discharge is always serious to security produce in mine. How to more accurate forecast the mine -discharge is till a question which the domestic and foreign experts and scholar are making great efforts to seek, especially pay attention to the mine discharge of the complex condition. This article established the mathematical model on the basis of knowing and grasping the hydrology geology condition, space structure of the water bearing medium. The model time and spatial separate, the boundary condition generalizing and the hydrological parameter selection are deeply researched. Using the popular groundwater numerical simulation software Visual Modflow simulate the mine discharge of the Research area for 30 years. And obtain the more satisfied mine discharge of every stage each mine.
