| Abstract: | The definition of overbreak and Relation between unstable block's volume and overbroken volume are discussed, and the methods to calculate block's position and volume are summed up to 3 kind: stochastic, determinate and half-stochastic, and instruction is put forward for further study on overbreak. The determinate calculation about position of the block incised by 3 joints, especially the hidden dangerous block are discussed and settled, and a simple method to calculate the block's volume approximatively is advanced. The overbreak calculation is instructionally significative in safe and efficient underground opening construction. |
