Problems solved by technology

However, after the mining area is mined, the mining area, abandoned roadway, etc. are left behind, and the vibration intensity and vibration propagation rate of the vibration signal passing through these areas have changed, which brings great challenges to the location and qualitative analysis of the seismic source. uncertainty
Inaccurate source location and characterization will seriously affect the application of microseismic monitoring technology

Embodiment Construction

[0019] Such as figure 1 As shown, three substations are set up, namely the first substation 1, the second substation 2, and the third substation 3, which are respectively arranged in the first monitoring area 4, the second monitoring area 5, and the third monitoring area 6. Each substation is used to monitor a monitoring area. The substation is powered by the underground monitoring host.

[0020] The three monitoring areas are the three working faces of the coal mine.

[0021] There are 8 detectors in the first substation 1, namely, the detector 101, the detector 102, the detector 103, the detector 104, the detector 105, the detector 106, the detector 107, and the detector 108; the second substation 2 There are 8 detectors in it, namely, the detector 201, the detector 202, the detector 203, the detector 204, the detector 205, the detector 206, the detector 207, and the detector 208; there are 8 detectors in the third substation 3. Detector, namely, detector 301, detector 302, det...

Abstract

The invention discloses a small mine earthquake monitoring system and a radio-detector arrangement method thereof. Underground substations are arranged in different underground monitoring regions in an arrangement mode which combines an inter-region distribution mode and an inner-region integration mode; each substation is used for monitoring one region so as to form inter-region distributed arrangement; each substation is connected with a plurality of radio-detectors at the same time and is used for receiving a shock signal and transmitting the received shock signal to the underground substations so as to form inner-region integrated arrangement; and each underground substation centralizes the signal and transmits the centralized signal to the ground. In the arrangement mode which combines the inter-region distribution mode and the inner-region integration mode, large-range and high-accuracy monitoring can be realized and effective guide information is provided for safe production of mines.

Description

Technical field [0001] The invention relates to a mine microseismic monitoring method, in particular to a mine microseismic monitoring system and a geophone arrangement method. The method can increase the monitoring area and improve the monitoring accuracy. Background technique [0002] Mine microseismic monitoring technology is a hot spot in domestic and foreign research in recent years. This technology installs geophones for monitoring mine vibration or rock fracture within the mine, and then transmits the data to the data storage and processing device, and then uses analysis software to analyze Interpret the vibration and analyze the vibration disaster of the mine based on the vibration situation. [0003] The utility model with publication number CN2687693Y discloses a microseismic monitor, which is placed downhole. The method adopted is to place an industrial control computer in an explosion-proof shell, the slot of the computer is connected with a data collector, and the she...
