Application of Geological Prediction and Blasting Technology in Construction of High Gas Tunnel
This paper takes a high gas tunnel project as an example to explore the application of advanced geological prediction technology and blasting technology.In the advance geological prediction of tunnel construction,TRT6000 advance prediction system is used to place seismic source and detector in the tunnel,and the seismic wave is emitted at the focal point and the reflected seismic wave is collected by sensor.After analysis by RV3D software,it is found that the left hole face K1 19+356-396 and the right hole face K119+294-334,The rock mass is relatively broken and there is fissure water,so advance support should be carried out,and the damage to loose surrounding rock should be reduced according to short excavation and weak blasting.In the blasting operation,in addition to calculating the number of holes,charge amount and other parameters,the innovative use of"blister mud+solid flame retardant material"hole sealing method to ensure the safety of blasting operation.
