Abstract: A new probability formula of block volume considering randomness of spacing and extension of joint planes is established by means of block theory and probability analysis. The relationship among spacing, extension and block volume is analyzed according to the formula. The traditional hemispheric projection method handled quantification index of block volumes is conquered; and the index can be obtained soundly by the formula. The applying prospects and adaptation of the formula are shown by project examples.

Key words: spacing of joint plane, trace length of joint plane, block volume, probability analysis
