摘要
介绍了地面摄影测量测定地下采场采空区体积的测量方法,叙述了在井下摄影、光束法平差数据处理、多项式拟合曲面进行采空区离散点插值及利用积分学原理进行采场采空区体积计算。通过山西省临汾某铁矿试验表明,这种方法操作简单,速度快,大大提高了采空区体积测量精度,值得在生产中推广应用。
This article describes the acceptance measurement method of measuring stope volume by the terrestrial photogrammctry and introduces underground photography, bundle adjustment,discrete points interpolation with polynomial fitting surface, calculating volume of mine in integral calculus principle. By the test in a iron mine,it shows this method is simple and fast. Also this method improves the measuring accuracy of production volume of ore greatly, and it is worth to promote in production.
