摘要
本文讨论了使用矩形钻探网打中随机定位的一组三维目标的概率估计。这组目标代表多个任意形态的矿体。本问题的复杂性在于难以使用解析方法加以解决。作者使用了数值积分方法,同时克服了计算中的一些主要难点。求解本问题的FORTRAN程序是在MV/4000计算机上运行的。试算例子包括一个供考核用的立方体目标及其分块,以及模拟实际情况的定位受约束的一组板状矿体。
Probability estimate of hitting a group of three-dimensional targets of random orientation using a rectangular drill network is deliberated. The targets represent several orebodies of arbitrary shape. The problem is too complicated to be solved analytically. The author used numerical integral method. Some major difficulties in computation have been coped with. FORTRAN program for the problem runs on a MV/4000 computer. Trial examples include a cubic target and its partitioned parts for program test, as well as a group of plate orebodies with a constraint orientation to imitate a real situation.
