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 mine driving face self-powered distributed earthquake monitoring system and method. A geophone is installed in a certain depth of a drill hole in a roadway wall and the geophone is adhered to and pushes against the wall of by using a carbon spring steel wire to realize tight coupling between the geophone and a drill hole wall, thereby greatly reducing construction difficulty and cost of repeated disassembly and assembly of the geophone, and solving the problems that the geophone is influenced by noise of the installation environment and wall adherence coupling of thegeophone when the geophone is installed in a shallow hole; and the mechanical vibration energy of a belt support under the coal mine is reasonably and effectively collected by a belt support self-powered device, and the energy is provided for an earthquake monitoring system connected therewith to guarantee that nodes work continuously and effectively. The defects of difficult wiring of a coal mine underground cable power supply mode, and frequent replacement of batteries and high maintenance cost of a battery power supply mode are solved with smaller cost, and mobility and adaptability of theearthquake monitoring system are improved.

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...
