摘要
钻孔抽放是煤矿瓦斯防治的主要措施,科学合理地布置钻孔是保证瓦斯抽放效果的关键。在ArcGIS环境下,借助其提供的空间分析计算工具,提出了核密度分析法、线密度分析法和缓冲区分析法3种分析思路,并对其原理和实现方法进行了阐述,最后通过软件编程实现了3种方法的集成应用程序,对钻孔布置实例进行了缺陷评价分析并生成了效果图,论证了密度分析方法对于钻孔缺陷分析的可行性。
This article based on ArcGIS environment, with its space analyzing and calculating tools, presented three analysis methods, such as kernel density analysis method, linear density analysis and buffer analysis method. And then, the paper described its principle and implementation. Finally, the paper realized integrated applications of the three methods with the help of custom programming. With the examples of bore hole layout of defect evaluation, this paper concluded the effect chart, and demonstrated the feasibility of the density analysis method for the defects analysis in drilling.
