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

Abstract:

Borehole track plays very important role in the process of analyzing and solving borehole inclination problems. The polar iso-distance 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.

Key words:polar iso-distance net; borehole track plane projection; borehole inclination analysis
