基于钻孔数据的勘探线剖面图自动生成方法

采用拓扑学研究了基于钻孔数据的平(剖)面图自动生成算法问题,给出了层次型钻孔数据库的构建方法,介绍了钻孔勘探线剖面图的绘制方法,包括倾斜钻孔计算、简单地质界线追踪连接、断层等地质构造的人工辅助绘制等,并以安徽马鞍山高村铁矿和江西城门山铜矿的钻孔数据为例分别绘制了直孔和斜孔的勘探线剖面图.研究结果表明:钻孔数据剖面连图与平(剖)面图相互切割自动连图属于同一类型问题,都属于二维矿山散乱数据的可视化问题,其核心是地质界线的拓扑关系、数据插补和智能追踪;将矢量栅格混合构模与智能识别相结合是一种可行的方法.

Automatic formation method of prospecting line profile map based on drill hole database

The problem of automatic linking algorithm of prospecting line profile map was studied. A new idea based on topology method was introduced, a method of hierarchy type database for geology drill data was given. The method of automatic formation of prospecting line profile map was given based on the drill database, including incline drill hole calculating, simple type ore body linking and manually aided drawing of fault, etc. In the end, the formations of straight and non-straight drill hole type prospecting line profile maps based on drill data of Gaocun iron mine in Maanshan and Chengmenshan copper mine in Jiangxi were described, respectively. The result indicates that the problem of automatic forming of prospecting line profile map based on drill or survey data is the same as the problem of automatic forming of geology cross-section map and it still has not been solved so far. Both of them belong to 2D visualization of mine dispersed data. A feasible method for this problem is to combine vector and grid model and intelligent identifing technique.
