| 摘 要： | 为实现煤矿瓦斯地质动态精准预测与可视化，基于煤层埋深、厚度、倾角、地质构造等多种因素，通过将相似的地质模块定义为同一微单元，在此基础上将反距离权重插值算法和递归邻域搜索策略与数据优化处理算法相结合，应用于瓦斯地质动态预测可视化系统开发。研究结果表明:根据递归邻域搜索算法模型开发的多级瓦斯地质图动态分析系统利用瓦斯地质基础数据可对矿井瓦斯含量、压力、涌出量等瓦斯赋存参数进行实时分析和计算，动态绘制散点图、等值线和区域预测图，使瓦斯区域预测图过渡更加平缓，显著提高预测的精准性及整体的显示效果，同时其制图耗时也无明显增加，可为高瓦斯矿井安全生产提供决策依据。

| Abstract: | In order to realize the dynamic and accurate prediction and visualization of gas geology in coal mine,based on various factors such as coal seam buried depth,thickness,dip angle and geological structure,the similar geological modules were defined as the same micro unit,and on this basis,the inverse distance weight interpolation algorithm and recursive neighborhood search strategy were combined with the data optimization processing algorithm and applied to the development of visualization system for the dynamic prediction of gas geology.The results showed that the dynamic analysis system of multi-level gas geological map developed according to the recursive neighborhood search algorithm model could analyze and calculate the gas occurrence parameters such as mine gas content,pressure and emission amount in real time by using the basic data of gas geology,and dynamically draw the scatter map,isoline and regional prediction map,so as to make the transition of gas regional prediction map more gentle.The accuracy of prediction and the overall display effect were significantly improved,and the drawing time-consuming was not significantly increased,which provides decision-making basis for the work safety of high gas mines. |
