针对开滦东欢坨矿开采煤 8诱发的顶板涌 (突 )水问题 ,首先采用五个物理场的多源地学信息复合研究方法对煤 8顶板充水含水层进行了富水性综合分区。此外 ,在充分分析煤 8至顶板充水含水层间岩段的岩性特征基础上 ,将据《煤矿安全规程》计算出的导水裂隙带发育高度进行了全方位的岩性场定性校正 ,并编制了煤 8回采冒落安全性分区图。在此基础上 ,耦合叠加分析煤 8回采冒落安全性分区和其顶板充水含水层的富水性分区结果 ,对东欢坨矿煤 8回采顶板涌 (突 )水条件进行了综合评价 ,提出了 A、B、C、D、E5个不同涌 (突 )水特征的分区划分方案。最后运用目前国际上先进的地下水流水质模拟评价的 Visual Modflow专业软件系统 ,建立了三维可视化渗流模型 ,并对待采的 2 0 86、2 188B回采工作面涌水量进行了动态实时预测。
In order to solve the problem of roof surging (sudden) water induced by coal 8 mining in Kailuan Donghuantuo Mine, a five-physics multi-source geo-information composite research method was firstly used to conduct comprehensive water-rich partitioning of coal-fired aquifer in coal roof. In addition, on the basis of fully analyzing the lithological characteristics of the rock section between the coal 8 and the roof water-filled aquifer, the lithological field is qualitatively calibrated in all aspects based on the development height of the water-carrying fractured zone calculated from the “Coal Mine Safety Code” And compiled a map of the safety of coal mining back to the 8th. On this basis, coupled with superposition analysis of coal mining safety zone 8 coal mining and its water-filled aquifer zoning results of roof aquifer, Donghuan Tuo coal mining 8 coal roof surging (sudden) water conditions were put forward a comprehensive evaluation A, B, C, D, E five different surge (sudden) water features zoning scheme. At last, using Visual Modflow professional software system, which simulates and evaluate the quality of groundwater flow in the world, a three-dimensional visualized seepage model is established and the prediction of water inflow from 2086,2188B working face is carried out.
