| Abstract: | A controlled blasting technology was applied to the construction of freezing thick gravel stratum section in the main shatt ot Xulou Mine. Rational blasting parameters ware designed according to the mechanics characteristics of the freezing gravel. Under the safety conditions of the freezing tubing, the construction rate was improved and the month shaft completed rate reached to 109 m with a smooth blasting standard. Such construction eliminated a transfer construction operation from the overburden construction to base rock construction. The paper summarized the technical key points of the excavation with the drilling and blasting method for the freezing thick gravel stratum section of the mine shaft. |
| Keywords: | freezing gravel stratum mine shaft blasting rapid excavation |
