摘要
为确保鹤壁矿区寺湾矿安全生产,采用国际通用的Visual Modflow地下水渗流模拟软件,以寺湾矿石炭系太原组二灰岩溶水大型放水试验为基础,建立了岩溶水三维渗流数值模型.通过该模型的识别和检验,成功模拟了放水试验所形成的渗流场和水位动态变化,利用此模型计算的设计疏降水平的涌水量与采用相关曲线外推法、漏斗均衡法和解析法计算结果相差不大,已成为矿井排水系统改造的重要参数,为受承压水威胁的太原组下夹煤的安全合理开采提供了科学依据.
In order to ensure the safety in coal mining, by using interntional Visual Modflow groundwater seepage simulation software, a three - dimensional seepage numerical model of karst water is established based on large scale outflow test of the second level limestone water, which is of Taiyuan formation belong to carboniferous system of Siwan mine in Hebi mining area. By the model distinguishing and testing, the seepage flow field and the water level regime variation in the outflow test are simulated successfully. The caleulative mine inflow of the designed descending level on the model is close to the use of .correlation curve extrapolation, the funnel equalization and analytical method. It has been as a significant parameter in reconstructing drainage system, which provided scientific basis for suffer confined water threatening Taiyuan folder safety and reasonable coal mining.
