摘　　要：为了提高煤层地质建模和资源量估算的效率,本文提出了网格法,并以某煤矿为例,在钻孔数据库的基础上,创建了煤矿的地表模型、块模型、断层模型等.本文的主要结论如下:1.通过分析和编辑空间数据,设计并创建了煤矿钻孔数据库.2.基于煤矿钻孔数据库,在三维可视化环境中显示了钻孔轨迹、样品值和其它一些地质信息.3.利用GPS当中存储的控制点数据创建了煤矿地表和断层模型.4.使用网格法创建了煤层块模型,并计算煤炭资源量.结果表明,该模型的使用取得了良好的结果.In order to meet the requirements of more efficient coal modelling and resource estimation, the Seam method is proposed, a case study of geological characteristics of one coal mine is presented in which the topography model, block model and fault were built based on the drillhole database. The main conclusions of this study are as follows. （1） Thorough analysis and organization of spatial data, design and setup of the coal mine drillhole database. （2） Based on the coal mine drillhole database, the drillhole trace with sample values and other geology information were displayed. （3） The topography model and fault were built by using location and elevation data from a GPS. （4） A block model with grade obtained by using the Seam method. In the end, the models are applied to the coal mine and the result shows that better results are achieved.
