Embodiment Construction

[0015] Such as figure 1 As shown, in the initial stage, the stress increases with the increase of the strain. When the increase of the stress reaches a peak value P, the stress decreases with the increase of the strain; In stage F, the failure form of the coal body is mainly stress rise-crack; and in the third stage T, when the stress is near the peak value, the failure form of the coal body is fracture-vibration; in the first stage F and the third stage T intersect In the second stage S, the damage form of the coal body is rupture-vibration.

[0016] Rockburst and mine earthquake monitoring system, including rockburst monitoring system 1 and mine earthquake monitoring system 2, the rockburst monitoring system and mine earthquake monitoring system share the underground power supply 3 and the underground monitoring host and switch 4; the rockburst monitoring system Including a junction box 11 and a pressure sensor 12, one end of the junction box 11 is connected to the pressure...

Abstract

The invention relates to a rock burst and mine earthquake real-time monitoring system and a method. The rock burst and mine earthquake real-time monitoring system comprises a rock burst monitoring system and a mine earthquake monitoring system which are arranged underground, wherein the two monitoring systems commonly share an underground power supply, an underground monitoring host and a switch. The rock burst monitoring system comprises a junction box and a pressure sensor, wherein one end of the junction box is connected with the pressure sensor, and the other end of the junction box is connected with the underground power supply through a pressure signal wire and a sensor power supply line. The mine earthquake monitoring system consists of a geophone which is connected with the underground power supply through a vibration signal line and a geophone power supply line; the underground monitoring host and the switch can keep the monitoring of the rock burst and the monitoring of the mine earthquake synchronously, and signals collected by the geophone and the pressure sensor can be transmitted to ground equipment through the underground monitoring host and the switch. The rock burst and mine earthquake real-time monitoring system realizes the synchronous real-time monitoring of the rock burst and the mine earthquake, and has wide application prospects in the fields of coal mine dynamic disaster monitoring and early warning.

Description

technical field [0001] The invention relates to a real-time monitoring system and method for rock burst and mine earthquake. Background technique [0002] Rockburst refers to the catastrophic dynamic phenomenon around the stope and roadway; mining earthquake refers to the dynamic phenomenon within the mining area; microseism refers to the dynamic phenomenon caused by rock mass destruction caused by mining. The above phenomenon will seriously affect or even destroy the mining production. Therefore, it is hoped that the breeding, development and occurrence of the above phenomenon will be monitored and early-warned, so as to provide a basis for safe mining of coal mines. [0003] The study found that mine earthquakes and rock bursts are related to each other, mine earthquakes can induce rock bursts, and strong rock bursts can cause mine earthquakes. Therefore, in the monitoring and early warning technology of rock burst, it is not enough to only monitor the change of the stres...
