The evaluation of rock burst proneness is the basis of risk assessment of rock burst in underground engineering. However

existing numerous evaluation indexes with different characteristics results in application errors frequently. After clarifying the concept of rock burst proneness

the evaluation indexes of rock burst proneness were summarized and categorized through a comprehensive literature review. From the perspective of acquisition methods of their values

the index of rock burst proneness(W

et

) and the coefficient of intensity brittleness（B） were analyzed. The inflection point of volumetric strain

as unloading control point in test process

was recommended to determine the value of W

et

. Thus

the traditional difficulty that the unloading point was hardly controlled during the test process

was solved. According to testing results

this method was proved to be scientific and effective. By c

omprehensively investigating the values of W

et

and B for different kinds of rock

the relationship of these two indexes was analyzed and the evaluation standard of B value was further improved. Therefore

this study provides a significant guidance for scientifically and reasonably evaluating rock burst proneness.
