摘要

通过对汉城矿区煤层气数据的分析,建立了煤层气空间数据库。确定了甲烷含量与主体构造线的关系,确定了构造控制瓦斯的缓冲区域半径,通过对区域的缓冲分析,将储层划分为渗流区、封堵汽化区三部分。通过对煤层厚度、瓦斯含量、煤层深度、煤层结构及顶底板结构条件密切作用的拼接分析,将主煤层煤层气开采划分为有利区、不利区和一般区。最后指出了开发的目标区。

Evaluation of Coal Bed Methane Resource Based on Mapgis in Hancheng Mining Area
The spatial database of coal bed methane (CBM)is established on the analysis of data about CBM in Hancheng mining area. the relationship between the content of methane and main structure line, the radius of buffer area for structure control of gas is confirmed, the storing layer is divided into three parts: seepage district, and blocked and vaporized district by the buffer analysis of the area. With the spliced analysis of coal thickness, content of methane, coal depth, coal construction and close function of roof and floor structure condition, the CBM exploitation of main coal seam is divided into advantageous, disadvantageous and common area. Finally it points out the target area of exploitation.
