摘要
用直角三角形数学公式推导出钻孔顶底板坐标计算公式,并设计出相应的VB程序,该程序能根据钻孔的孔斜倾角、方位角、孔深位置、见矿孔深的测定结果以及孔口坐标数据,自动计算顶底板坐标,并能保存和打印计算结果。程序经实际工程检验,可满足需要。
This article uses right-angled triangle math formulae to derive the coordinate-calculation formula of top and bottom plate of borehole, and to work out the program with VB. The program could calculate automatically the coordinate of top and bottom plate according to the borehole＇s inclination angle, azimuth, the position of borehole depth, measuring result of borehole depth discovery, and hole top coordinate data, and could save and print the result. The program could satisfy the demand by way of actual engineering test.
