Rational Millisecond Time Setting for Coal Blasting Mining
Abstract：Base on the basic principle of blasting and with the fuzzy mathematics tools and the blasting cases, the paper had a comprehensive multi factor evaluation for the rational millisecond time setting of blasting. The main influence factors are considered with a throw distance, a stack height and a flatness of the coal face. A Weighting distribution between each factors and function relationship of blasting effect applied by the each factors were established with statistic experiments, experts evaluation and other methods. The fuzzy comprehensive evaluation value was made from the actual results. The optimum time difference was made from a max subject principle.
