Embodiment Construction
[0034] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0035] Such as figure 1 , figure 2 Shown, a kind of tunnel advance geological prediction method, its steps are:
[0036](1) Three boreholes 2a, 2b, 2c are drilled on the same side wall 4 in the tunnel 1. The boreholes 2a, 2b, 2c are parallel to the bottom plate of the cavern and perpendicular to the direction of the cavern. The distance between the drill holes is 5-10m. The floor height of the chamber is 1.5m, the hole diameter is 6cm, and the depth is 2m;
[0037] (2) Place an appropriate amount of butter as a coupling agent at the bottom of the borehole 2a, bury a highly integrated intelligent three-component geophone 3a at the bottom of the borehole 2a, adjust the position of the three-component geophone 3a, and m...

The invention provides an automatic monitoring system for the advance geological prediction of tunnels. The automatic monitoring system includes a data acquisition system, a data transmission system,and a control and data analysis system; the data acquisition system is composed of three highly-integrated intelligent three-component geophones; the data transmission system is composed of a synchronous communicator and a signal line; and the control and data analysis system is composed of a host and a control analysis program. The operation process of the system includes eight steps, namely, turning on the host, setting acquisition parameters, starting the system to wait for acquisition, blasting and tunneling a tunnel face, triggering acquisition, acquiring and storing data, transmitting the data, and checking the data, and therefore, the advance geological prediction can be realized. With the automatic monitoring system of the invention adopted, working conditions are greatly improved,and personnel risks are reduced; automatic and continuous advance geological prediction of the tunnels is realized; labor intensity is reduced; construction can be accelerated; and operation risks can be reduced. The automatic monitoring system of the invention can be widely applied to the advance geological prediction of unfavorable geologic bodies in the excavation of underground tunnels in thetransportation, water conservancy, and mining industry.
Description
technical field [0001] The present invention relates to the technical field of artificial seismic wave acquisition and processing, more specifically to a tunnel construction advance geological prediction method using tunnel face blasting as the seismic source, and also relates to an advanced tunnel construction method using tunnel face blasting as the seismic source The automatic monitoring device for geological prediction is suitable for advanced geological prediction of unfavorable geological bodies in the excavation of underground caverns in transportation, water conservancy, and mining industries. Background technique [0002] The 21st century is an era of great development of tunnels and underground spaces. With the expansion of the length and scale of tunnel projects, the complexity and variability of geological conditions encountered are also increasing. Insufficient detection methods in the early stage will pose a greater threat to the safety of tunnel construction, ...
