| Abstract: | Freezing shaft sinking method is an effective method of sinking deep thick clay strata, and full frozen method is a recommended one. Practices reveal that drilling and blasting method may speed sinking. To enhance the efficiency of drilling and blasting it is necessary to correctly choose drilling equipment, optimum designing parameters of blasting and to perform full face blasting, under the prerequisite of ensuring the safety of freezing pipes. |
