Abstract

Provided is an advanced detection system for tunnelling disasters. The system comprises: an electromagnetic wave detector (1), a signal collection amplifier (2), a controller (3), an inclination sensor (4), a vibration sensor (5), a wireless communication circuit (6), a wireless base station (7), a gateway (8), an industrial Ethernet (9) and a monitoring host (10). Also provided is an advanced detection method for tunnelling disasters, comprising: the controller (3) controlling the electromagnetic wave detector (1) to operate according to the signals of the inclination sensor (4) and the vibration sensor (5), detecting wave reflection signals of electromagnetic waves in front of the tunnelling, the wave reflection signals of the electromagnetic waves arriving at the monitoring host (10) via the signal collection amplifier (2), the wireless communication circuit (6), the wireless base station (7), the gateway (8) and the industrial Ethernet (9), and the monitoring host (10) respectively analysing all the received signals, judging whether there are situations such as stress accumulation, geological structure abnormality and so on in the front of the tunnelling or not, and providing an early warning of the geologic hazard in the front of the tunnelling of mine or culvert tunnels.

Description

technical field [0001] The invention relates to a detection method and system, in particular to a method and system for advanced detection of tunneling disasters used in mines or underground roadways for real-time detection and early warning of geological disasters ahead of tunneling. technical background [0002] During mine or underground culvert excavation operations, geological disasters such as water inrush and rock burst often occur. For a long time, people have adopted the method of first using the geophysical prospecting method to find out the geological conditions in front of the excavation. However, due to the depth of the artificial exploration method, the accuracy of the detection is not ideal, and some hidden dangers are difficult to find, resulting in the excavation. Accidents occur, causing casualties and economic losses. Contents of the invention [0003] The purpose of the present invention is to provide a method and system capable of real-time detection ...
