This article provides an example to illustrate and explain the problem on borehole. Three boreholes are sunk at 3 points of an equilateral triangle whose sides are 480 m each. Is West of Q and R is North of midpoint PQ. Boreholes and R-reach the upper surface of a rich coal seam at 100 m, 220 m, and 260 m [...]
