摘 要:为了减少煤矿瓦斯地质图的绘制工作并增加其可信度,基于AutoCAD、Surfer和Excel软件,提出了一种绘制煤矿瓦斯地质图的新方法。该方法首先运用Surfer软件分别提取地形图和煤层底板等高线图中等高线的高程,并得到煤层埋深等值面;而后根据煤层瓦斯压力和含量实测数据,分别得到瓦斯压力与埋深和瓦斯含量与埋深的拟合方程,并将拟合方程导入Surfer软件后,生成煤层瓦斯压力等值线和瓦斯含量等值线;最后将煤层埋深等值面、瓦斯压力等值线和瓦斯含量等值线导入到Surfer软件,并通过编程处理后,生成矿井瓦斯地质图。实践表明,该方法不仅能自动快速生成瓦斯地质图,并且能准确反映实际情况,提高了瓦斯地质的可靠性。In order to reduce the drawing work of mining Gas-geologic map and increase its credibility,a new drawing method based on AutoCAD,Surfer and Excel software,was put forward.Firstly,the contour lines elevation of topographic map and floor contour map of coal seam were extracted using Surfer software,and the equivalent surface of coal seam buried depth is obtained;secondly,the fitting equations of gas pressure and depth and gas content and depth were obtained according to the measured data of coal seam gas pressure and content,and the gas pressure contour and gas content contour of coal seam were generated.When the fitting equation is imported into Surfer software;finally,the mine gas geological map was generated,through design and programming after the coal seam buried depth contour,gas pressure contour and gas content contour were all loaded into Surfer software.Practice shows that this method can not only generate gas geological maps quickly and automatically,but also reflect the actual situation and improve the reliability accurately.
