Earthquake monitoring device for mine area and use method of earthquake monitoring device

Abstract

The invention relates to the technical field of earthquake monitoring, in particular to a mine area earthquake monitoring device and a using method thereof.The mine area earthquake monitoring device comprises a vertical pipe, a first rope is fixed to the top of a battery bin, an extrusion fixing device is installed between the vertical pipe and the side wall of a deep well, and the extrusion fixing device is used for fixing the vertical pipe into the deep well; a seismometer is installed in the vertical pipe through a leveling device, the leveling device is used for keeping the seismometer in a horizontal state during working, a drainage device is installed between the vertical pipe and the extrusion fixing device, and the drainage device is used for draining water permeating into the vertical pipe in rainy days. According to the device, through the arrangement of the drainage device, accumulated water in the vertical pipe can be drained when the monitoring device is used, so that the situation that the working performance of the seismometer is damaged due to the accumulated water in the vertical pipe is avoided, meanwhile, the seismometer is kept to work in a horizontal state, and the working performance of the seismometer is kept.

Description

technical field [0001] The invention relates to the field of earthquake monitoring, in particular to an earthquake monitoring device in a mine area and a method for using the same. Background technique [0002] Seismic monitoring refers to the monitoring and measurement of earthquake precursor anomalies and seismic activity before and after an earthquake. There are several classification methods for earthquake monitoring. One is the division between professional and public, which refers to professional seismic stations and some group measuring points. The former mainly uses monitoring instruments, such as water level gauges, seismographs, and electromagnetic wave measuring instruments. Monitoring microscopic precursor information of earthquakes; the latter mainly relies on means such as shallow water wells, water temperature, and abnormal animal and plant activities to observe macroscopic anomalies before earthquakes. [0003] The prior art discloses some invention patents ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, when seismic monitoring is carried out on the mining area, the surface and shallow seismic monitoring in the mining area is greatly affected by the behavior of surface excavation and underground mining. In order to carry out effective base monitoring in the mining area, underground seismic monitoring is generally used , so that the seismometer is placed at a certain depth underground, so that when it encounters rainy weather, the well is prone to water seepage, and rainwater may penetrate into the inside of the seismometer, resulting in damage to the internal circuit of the monitoring device, so it is necessary to infiltrate the inside of the detection device water to remove
