Embodiment

[0050] An embodiment of the invention provides a self-powered distributed seismic monitoring system for a mine driving face.

[0051] The following will be combined with the accompanying drawings Figure 1-6 This embodiment will be described.

[0052] A self-powered distributed seismic monitoring system for a mine excavation face in this embodiment includes a belt bracket self-powered device, an acquisition substation, a data transmission cable, and a shallow-hole geophone; the following describes several components in detail.

[0053] (1) Belt bracket self-powered device

[0054] Please refer to Figure 1-2 , the self-power supply device of the belt bracket fixes the cantilever beam supported by the piezoelectric material on the belt bracket through the casing, and the belt conveyor drives the mechanical vibration energy generated by the belt bracket during material transportation to drive the piezoelectric material to deform. The vibration energy of the belt support that ...

Abstract

The invention relates to a self-powered distributed seismic monitoring system and method for mine excavation working face. In the present invention, the geophone is installed in a borehole with a certain depth on the roadway wall, and the carbon spring steel wire is used to push the geophone against the wall, so that the geophone and the borehole wall are tightly coupled, and the geophone is greatly reduced. The construction difficulty and cost of repeated disassembly and assembly solve the problem of seismometer being affected by the noise of the installation environment and the wall-attached coupling when installed in a shallow hole, and the mechanical vibration energy of the belt bracket in the coal mine is collected reasonably and effectively through the self-power supply device of the belt bracket , and provide energy to the seismic monitoring system connected to it to ensure the continuous and effective work of the node. With a relatively small cost, it solves the shortcomings of the cable power supply method in the coal mine, the difficulty in wiring, and the battery power supply method, which often replaces the battery and requires high maintenance costs, and improves the mobility and adaptability of the earthquake monitoring system.

Description

technical field [0001] The invention relates to an earthquake monitoring system and method, belonging to the technical field of mine seismic exploration, in particular to a self-powered distributed earthquake monitoring system and method for a mine excavation working face. Background technique [0002] The promotion and application of coal mine automation and intelligent mining technology requires frequent, dynamic and precise detection in front of the tunneling face. [0003] Currently commonly used advanced seismic detection instruments and methods are still in the stage of on-site data collection and ground processing and interpretation. In field application of coal mines, there are often long periods of detection results, inability to realize coordinated operations of exploration and excavation, and untimely acquisition of structural information in front of the excavation working face, which seriously affects the speed of mine working face roadway excavation, making it i...
