立井基岩爆破对井壁和冻结管的爆破振动观测

Vertical Shaft Bedrock Blasting of Frozen Tube Wall and Blasting Vibration Observation

用爆破法进行立井基岩爆破时,由于基岩与井壁是紧密接触,所以爆破振动从基岩能够很好的传递给井壁。因此可通过振动强度的测试,来判断爆破对临近冻结管和已浇井壁的影响程度,及时调整爆破参数和爆破方法,保证冻结管和已浇井壁安全。

Using the vertical shaft bedrock in blasting method, due to the bedrock and borehole wall is close contact, so the blasting vibration from bedrock is good to the wall. So by the strength of the vibration test, judging blasting near the frozen pipe and has the influence degree of the water wall, timely adjusted blasting parameters and blasting method, to ensure that the frozen pipe and has water the wall safe.
