| Abstract | Sixty nine failures in the Mae Moh Mine occurred between 1984 to 1993. The
failures were in four modes, i) bedding plane failure, ii) fault plane failure and upward sliding
along bedding plane, iii) bedding plane failure and shearing through rock substance, iv)
circular failure . Back analyses of the failure slopes using the by HOEK & BRAY (1981), and
SARMA (1979) methods showed that the mobilized angles of internal friction for bedding
plane were close to the residual shear strength obtained from laboratory direct shear tests.
Post failure monitoring of a block sliding revealed a definite correlation of movement rate
with precipitation. The analysis and piezometer readings suggested effectiveness of horizontal
drainage.
