Abstract:

In dimension stone quarrying operation, fracture existence with the number of joints, the sum of joint spacing, the number of joint sets and the spatial relationship among joint sets in these quarries has affected to the block yield ability and the effectiveness, but it has lacked the evaluation of joint sets to dimension-stone extracting ablity, so far. The paper suggests how to evaluate the impact of joint set on block yield ability from analysis on the number of joint sets, the number of joints, the sum of joint spacing in sets and intersection anggles between joint sets. The paper study is applied to calculate at three quarries at the Southern Central region from collecting joints by scanline on the ground. The result contributes classify the extracting ability of dimension stone based on joint sets in rock mass.
