摘要
探明煤层的展布情况对煤矿的安全生产至关重要。基于大量的穿层瓦斯抽采钻孔的数据,运用全角全距法求出钻孔在煤层(顶)底板控制点三维坐标,并以矩阵的形式建立钻孔数据库,利用surfer图形处理功能,绘制煤层曲面图、等值线图等,实现煤层产状可视化。通过建立的实际煤层地质模型验证了此方法是有效的、可行的。
It is very important to prove coal seam distribution situation for coal mine safety production. Based on the data with a lot of cross layer gas drainage drillings, using the full - width range method to obtaine the drilling points＂ three - dimensional coordinates in the coal seam floor, and establish the database in the form of a matrix, using surfer powerful graphics processing capabilities to draw seam floor surface models and contour map, making the coal seams visualization, it has proved that the way is effective and feasible through the establishment of the actual coal geological model.
