摘要
为了绘制黄白茨矿10#煤层和12#煤层的瓦斯地质图,根据现场测得的瓦斯含量数据,利用等值线绘制软件surfer8.0,采用Kriging网格化方法绘制了10#、12#煤层瓦斯含量等值线,并通过Auto Cad 2008输出,准确绘制10#煤层和12#煤层的瓦斯地质图。从绘制的煤层瓦斯地质图可以看出,黄白茨矿瓦斯含量基本上是随着深度的变化呈线性增加,井田东部瓦斯含量大于西部,埋藏越深,瓦斯含量越大,基本与已采区域相对瓦斯涌出情况相符合。采用Kriging网格化方法解决了空间连续性变化的属性非常不规则时较难准确绘制地质图的问题,因此Kriging网格化方法可以用来绘制煤层的瓦斯地质图。
In order to draw gas geological map for No.10 and No.12 coal seams of Huangbaici mine, it is necessary to draw gas content contour line for No.10 and No.12 coal seams according to measured on-site gas content data by using drawing software Surfer 8.0 and applying Kriging gridding method, and then to accurately draw gas geological map for No.10 and No.12 coal seams by use of Auto Cad 2008 output. As can be seen from the gas geological map, gas content of Huangbaici mine shows an linear increase as depth varies, gas content at east field is larger than that at west, and the large burial depth, the greater the gas content, which basically accords with gas emission status at the exploited area. Kriging gridding method can solve the problem that it is difficult to accurately draw geological map when attribute of spatial continuity variation seems highly irregular, therefore, Kriging gridding method can be applied to draw gas geological map of coal seam.
