| Abstract: | 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. |

| Keywords: | Stoop-and-room method Pillar strengh Equivalent wide |
