极等间距网在钻迹成图及孔斜规律分析中的应用

钻孔轨迹图在分析和处理钻孔偏斜问题中起着非常重要的作用。极等间距网因具有较高的工程精度、直观性和准三维特性，既可用来描述和绘制钻孔偏斜轨迹图，也可为分析钻孔偏斜规律等问题提供详实的图形信息。以某铁矿帷幕灌浆部分试验孔的测斜数据为例，介绍了极等间距网在钻孔轨迹成图和钻孔偏斜规律分析中的初步应用。

Application of Polar Iso-distance Net in Drawing Borehole Track Plane Projecion and Analysing Borehole Inclination Law

Borehole track plays very important role in the process of analyzing and solving borehole inclination problems. The polar iso-distanee net, owing to its high engineering accuracy, vivacity and quasi three dimensional characteristics, can be used to picture and draw borehole track plane projections and to be helpful in providing detailed graphics information for analyzing borehole inclination law. By the case of some inclination survey data of curtain grouting testing borehole in an iron mine, the paper introduced the preliminary application of polar iso-distance net in borehole track drawing and borehole inclination law analysis.
