摘要
在分析和综合煤田勘探地质资料的基础上,从钻孔数据的组织方法入手,对钻孔柱状图自动生成的设计思想、实现技术、岩性花纹的填充方法、岩性柱状和缓冲线绘制算法等生成方法做了分析和阐述。针对地层与岩层描述文字的关系很难协调的问题,提出了一种新的基于MapGIS版面文字自动换行思想的缓冲线绘制方法,并对其进行了详细论述。在MapGIS6.7平台下,以MFC类库二次开发方法为主,运用该生成方法实现了钻孔柱状图的自动生成。此生成方法实现了地质图形与空间数据的良好结合,做到了图形与属性的互查,充分发挥GIS功能,降低了程序的开发难度。最后经黄陇实际钻孔资料验证,本方法生成图形美观协调,满足了实际工作的需要。
On the basis of analyzing and synthesizing the geological data of coalfield exploration,starting from the organization methods of borehole data,we analyse the design idea, the implementation technology, the filling method of lithology pattern, lithological geological column and buffer line drawing algorithms, etc. According to the problems that it is difficult to deal with the coordinate relationship between the stratum and the lithology description with words,we propose a new buffer line drawing method based on the atomatic text layout idea ,and give a detailed description in this paper. Based on the MapGIS6.7 platform,the MFC secondary development method and other methods ,the automatic generation of bore historgrams is realizaed. It makes good adhesion of the geologic graphic and spatial data, makes inter-checking between graphics and their attributes, gives play to the full function of GIS, and decreases the development difficulty. Finally,the method is verified by the practical borehole data of HUANGLONG,which can create beautiful and coordinative graphics,and satisfy the demands of practical work.
