| Abstract: | Under the condition of totally loose and squeezing,the coefficient of bulk increase can provide a pivotal evidence for calculating compensating space in cutting blasting and tight blasting.Based on the specimen of powder ore and block ore,the coefficients of bulk increase at the condition of fully loose and squeezing are tested,which provides an important and scientific guidance for blast compensating space. |

| Keywords: | bulk increase character coefficient of bulk increase compensating space |
