Taking extraction metal quantity and average grade as the assessment indexes,the range analysis and variance analysis of orthogonal test were conducted to obtain the position of a trench tunnel:double trench tunnels have a separation distance of 24 m,with a horizon- tal level of 118 m.Along with the scene implement,ideal test results have been achieved for refinement caving.
