Background technique
Since exothermic reaction mainly occurs for static breaking agent, when practical application this method, reaction is in narrow space and to lead
It is carried out among hot poor blasthole, with the aquation of cracking agent, a large amount of heats of hydration generated in the short time can not pass through in time
Surrounding medium export, causes the moisture in static breaking agent slurry to gasify rapidly, generates biggish steam pressure.When the steaming of generation
When steam pressure is greater than the cohesive force between static breaking agent slurry and blasthole hole wall, punching phenomenon occurs for static breaking agent.
Have experiments have shown that, the test block of plain concrete single hole can generate three Cracks during static crushing, cracking direction with
The intensity of concrete microscopic units is related, the low destruction at first of unit intensity.And the distribution of unit intensity has randomness, causes
Randomness is also presented in the appearance of crackle.The direction of check of plain concrete diplopore test block is related with pitch of holes, when pitch-row is less than minimum
When the destruction radiation scope of burden and static breaking agent, crackle is appeared between two holes.In order to control the direction of crackle, having must
Reduce pitch of holes, but reduces pitch of holes and will increase construction cost again.
