Distributed coal mine rock burst monitoring method

Abstract

The invention relates to a distributed coal mine rock burst monitoring method, belonging to a ground pressure monitoring method. The existing industrial Ethernet in a coal mine integrated automation system can be used for information transmission, a network sensor provided with an Ethernet interface is connected with a network, multiple measurements such as electromagnetic radiation, acoustic emission, micro-shock and the like which are used for reflecting signals of rock burst can be carried out, the measurement signals are transmitted into a host machine for monitoring the rock burst through the industrial Ethernet, and the host machine is used for analyzing, processing and locating a seismic source so as to realize rock burst monitoring; a main core of the network sensor is a singlechip provided with an Ethernet controller, and the measurement of three signals of electromagnetic radiation, acoustic emission and micro-shock can be realized by analog-to-digital conversion through three channels; and each sensor has the respective IP address. The method can be used for extracting features of various signals, carrying out event relativity analysis, extracting data fusion and event general features with different information, locating the seismic source and providing the analysis result of rock burst event.

Description

technical field [0001] The invention relates to a ground pressure monitoring system, in particular to a distributed coal mine rock burst monitoring method. Background technique [0002] Rockburst is a mine earthquake induced by mining. Rockburst, also known as rockburst, refers to the dynamic phenomenon of sudden and violent destruction of the rock mass around the shaft or working face due to the instantaneous release of elastic deformation energy, often accompanied by coal rock burst. Object throwing, loud noise and air waves and other phenomena. It is very destructive and is one of the major disasters in coal mines. [0003] The methods that can realize online real-time monitoring of rock burst mainly include electromagnetic radiation method, acoustic emission method (ground sound method), microseismic method, etc. Corresponding to various monitoring methods, there are also corresponding different monitoring systems for rock burst. [0004] The electromagnetic radiation ...

Problems solved by technology

[0009] 2) At present, these rock burst monitoring systems are centralized monitoring systems, which can only detect 4, 8 or 16 channels. The number of monitoring channels is limited, and the measurement channels cannot be expanded arbitrarily according to the needs of the site. With coal mining, when the site changes, the system layout needs to be changed accordingly, which is inconvenient to use

When changes are required, the entire system needs to be rearranged, which is inconvenient to use
