煤矿开采过程中挖掘、回采和排水等活动对煤层水系统地质结构、水文地质参数和水动力条件的影响显著。本专题在采煤驱动下煤层水系统地质结构和水文地质参数时空变异规律的基础上，构建结构-参数-边界协同动态校准的地下水流和溶质运移耦合数值模型，精确刻画煤层水系统采煤过程中诱发的结构演化及参数变异和边界转化过程，进行矿井水量质演化过程的准确模拟。\n
\n本数据集采用自主开发构建的结构-参数-边界协同动态校准的地下水流和溶质运移耦合数值模型进行模拟计算产生。数值模型的建立依据研究区地质、水文地质、气象、矿区规划等公开资料，并利用2007年《内蒙古自治区东胜煤田纳林河矿区二号井田煤炭勘探报告》中提供的MD23、MD27两个水文地质钻孔的天然水位和抽水试验实测数据，对模型参数进行了校正。校正后的模型能够较好地反映研究区天然状态下的流场特征和水均衡特征。涌水量动态预测数据通过在模型中设置首采工作面在不同开采阶段的工作面边界条件和扰动区参数后计算得到，为评估预测精度，本数据集中还提供了用于对比的涌水量实测值。数据集共包含10组数据，其中每组数据包含3个数据点。", "ds_source": "

The excavation, backfilling, and drainage activities during coal mining have a significant impact on the geological structure, hydrogeological parameters, and hydrodynamic conditions of the coalbed water system. Based on the spatiotemporal variation laws of geological structure and hydrogeological parameters of coal seam water system driven by coal mining, this topic constructs a coupled numerical model of groundwater flow and solute transport with structure parameter boundary collaborative dynamic calibration, accurately depicting the structural evolution, parameter variation and boundary transformation process induced during coal mining of coal seam water system, and conducting accurate simulation of the evolution process of mine water and quality.\n
\nThis dataset is generated through simulation calculations using a self-developed structure parameter boundary collaborative dynamic calibration coupled numerical model for groundwater flow and solute transport. The establishment of the numerical model is based on publicly available information such as geology, hydrogeology, meteorology, and mining area planning in the study area. The model parameters were calibrated using the natural water level and pumping test data from two hydrogeological boreholes, MD23 and MD27, provided in the 2007 \"Coal Exploration Report of the Nalinhe Mining Area in Dongsheng Coalfield, Inner Mongolia Autonomous Region\". The corrected model can better reflect the flow field characteristics and water balance characteristics in the natural state of the study area. The dynamic prediction data of water inflow is calculated by setting the boundary conditions and disturbance zone parameters of the first mining face at different mining stages in the model. To evaluate the prediction accuracy, this dataset also provides measured water inflow values for comparison. The dataset consists of 10 sets of data, with each set containing 3 data points.
