Device for real-time tracking and early warning of mine composite type coal and rock dynamic disasters

Abstract

The invention discloses a device for real-time tracking and early warning of mine composite type coal and rock dynamic disasters. The device comprises a microseismic signal acquisition unit, a gas parameter collector, a data analysis and reasoning module, a voice player, a control module, a data system and an original data analysis result display unit; the microseismic signal acquisition unit is in signal connection with the data system through a cable, the gas parameter collector is in signal connection with the data system through a cable, and the data system is in signal connection with thedata analysis and reasoning module through a cable; and the data analysis and reasoning module is in signal connection with the voice player, the control module, the original data analysis result display unit and an original data analysis result uploading unit through a cable, and the data system is in signal connection with the original data analysis result uploading unit through a cable. The device is suitable for all coal mines with coal and gas outburst and rock burst dangers, particularly outburst mines with rock burst dangers and mines with large mining depths and strong mine pressure.

Description

technical field [0001] The invention relates to the technical field of monitoring devices, in particular to a device for real-time tracking and early warning of coal-rock dynamic disasters in mines. Background technique [0002] Coal and gas outburst is an extremely complex gas dynamic phenomenon in coal mines, and it is one of the most serious natural disasters in underground mines. The recognized outburst mechanism holds that: "coal and gas outburst is the result of the combined effect of in-situ stress, gas, and coal's physical and mechanical properties"; according to this point of view, the control of coal and gas outburst in China mainly focuses on the control of gas factors In terms of research and development and application of various gas drainage technologies, the industry's "double six" indicators have been proposed to prevent coal and gas outburst control—that is, after pre-extraction of coal seam gas, as long as the coal seam gas pressure is less than 0.6 MPa, t...

AI Technical Summary

Problems solved by technology

[0006] 2) The current outstanding prediction index can only reflect the outstanding gas factor well, and lacks the detection means and prediction index that can well reflect the ground stress factor;

[0007] 3) The ground stress factor plays a relatively large role in the current outburst accidents; the reason for this is that more and more old mining areas have been transferred to deep mining, insufficient scientific research investment in ground stress outburst prevention and early warning measures, and no mature detection methods Used for monitoring, tracking and early warning of changes in ground stress
