“Working resistance” model selection

Based on the histogram data and in combination with the actual local operation

experiences, the scientific model selection utilized the “transmission rock beam”

mechanics theory of the academician Song Zhenqi and reasonably determined the working resistance of supports to guarantee the appropriate working resistance and prevent the adverse events such as waste of investment and occurrence of roof accident or damage of mass supports.
