Method of roof instability rating |
摘要 |
A method for predicting potential mine roof failures which generally includes the steps of identifying influence factors that affect mine roof instability, quantifying each influence factor, multiplying each influence factor by a numeric weight factor to obtain a weighed influence factor for each influence factor and calculating a mine roof instability rating based on the weighted influence factors. Supplemental support may be recommended in areas where the mine roof instability rating shows increased risk of mine roof failure.
