ABSTRACT
According to quality modulus of lifting winch (hoist) mentioned by the article 432 of coal mine safety regulations, using hoist mechanical brake power balance equation, derived relationship of maximum static torque multiples K, safe braking deceleration and quality modulus M. On the basis of detailed analysis, Obtained: (1) The range of he inclined shaft, shaft hoisting system quality modulus M meeting the relevant provisions, (2) The basis and results of the four division of big, normal, small, small, smaller of inclined shaft, shaft hoisting system quality modulus M, Using the software of MATLAB, study corresponding variation of different inclination angles between K and M. The examples illustrated that the brake mode determined by quality modulus is feasible.
