Problems solved by technology
In the advanced geological prediction process of the seismic wave method, in order to make the energy propagate into the rock formation and enhance the resolution of the reflected signal, high requirements are placed on the installation standards of the on-site emulsion explosives and detonators. Failure to install will lead to the loss of the reflected signal. failure, causing unnecessary waste of time and cost
However, due to the soft nature of the emulsion explosive and the roughness inside the blasthole, the detonator inserted into the explosive is easy to fall off during the process of pushing the explosive into the blasthole. great potential risk
[0004] At present, there is still no effective device to solve this problem. On-site construction usually pushes the detonator insertion end towards the blast hole. Although this measure reduces the probability of the detonator falling off, it still does not fundamentally solve this problem. The invention aims to solve this common problem in tunnel seismic wave forecasting
