Problems solved by technology

At present, there are mainly two types of electromagnetic radiation early warning equipment: portable and online. The portable type cannot realize real-time analysis and upload of data. The online type has limited measuring points, relatively fixed positions (mainly arranged in key areas), and relies on wired data transmission. has certain limitations
[0004] However, in the electromagnetic radiation method of the prior art, most of them only judge the electromagnetic signal collected from a certain part of the mining area, and in the mining area, activities such as coal cutting often also cause changes in the electromagnetic signal of the mining area, so It is easy to cause misjudgment

Abstract

The invention discloses a coal rock mining area dynamic disaster monitoring system and method. The system comprises a mining area monitoring unit, a non-mining area acquisition unit and a monitoring terminal, wherein the mining area monitoring unit is used for acquiring coal rock condition related signals at all positions of the working face of a mining area; the non-mining area acquisition unit is used for acquiring coal rock condition related signals at all positions of a non-mining area in a mine; the monitoring terminal is used for calculating a critical value through an early warning algorithm according to the coal rock condition related signals, acquired by the non-mining area acquisition unit, at all positions of the non-mining area in the mine; when the coal rock condition relatedsignals, acquired by the mining area monitoring unit, at all positions of the working face of the mining area exceed the critical value, an alarm is given out. According to the method, electromagneticradiation distribution characteristics of the mining area of the mine and the evolution rule of the electromagnetic radiation distribution characteristics along with time can be mastered, and the system and method have great significance in realizing accurate monitoring and early warning of coal rock dynamic disasters and prevention and control of the coal rock dynamic disasters. In addition, themethod is also applicable to explosion disaster prevention and control of non-coal mines, and can effectively improve the mine production safety condition.

Description

technical field [0001] The invention relates to the fields of mine safety and monitoring, in particular to a system and method for monitoring dynamic disasters in coal and rock mining areas. Background technique [0002] my country's coal mining conditions are complex, and coal-rock dynamic disasters are one of the main disasters in coal mines. As the mining depth continues to increase, the frequency, intensity, and degree of damage of coal-rock dynamic disasters are on the rise, and the number of occurrences and casualties are also on the rise. The monitoring and early warning of coal-rock dynamic disasters mainly include static index method and geophysical method. The amount of information obtained by the static index method is limited and the accuracy is low, while the geophysical method can realize real-time, dynamic and continuous monitoring. [0003] Electromagnetic radiation generated by rock deformation and fracture is a relatively common physical phenomenon. As a...
