| Abstract: | This article shows an analysis of the bordering condition of the overbreak block in the adit PD\-6 of a pump\|storage hydroplant and a determination of types and characters of overbreak block, on the basis of the investigation of overbreak in this adit, and an assessment of volume calculation and distribution model for each type of overbreak block by using a self\|written calculating program. These will be very useful in the assessment of the overbreak in underground workings and of the stability of workings in construction as well as their reinforcement. |
