摘　　要：本文提出了在缓倾斜、倾斜、急倾斜矿体与矿柱不垂直时矿柱强度的估算方法，用等效宽度代替实际宽度考虑了矿柱与矿体不垂直时对矿柱强度削弱的影响这一重要因素。In this paper the estimaitng method of a pillar strengh is gived out when one is off perpendicular a ore body which is getlegrade,grade or steep-grade.This one important factor of influencing on pillar strengh is consided in the calculating farmula after the equivalent wide take the Place of the real wide.
