Abstract

The invention belongs to the technical field of safety production, and particularly relates to a dynamic disaster modal early warning method based on real-time monitoring data. The dynamic disaster modal early warning method based on the real-time monitoring data comprises the steps that (1) various parameter data of mine dynamic disaster are recorded according to a variety of installed real-timemonitoring sensors; (2) a continuous differentiable modal function f (x) and an upper envelope S (x) of the continuous differentiable modal function f (x) are established by using pre-recorded data sequence q (x) of the occurrence of dynamic disaster as sample data; and (3) the possibility of the dynamic disaster is calculated according to the relative relationship between S (x) and f (x), and therelative correlation between a change rate delta S (x) of real-time monitoring data and a derivative f '(x) of f (x). The dynamic disaster modal early warning method based on the real-time monitoringdata uses historical data to construct a modal function. According to the monitoring and appearing of mine dynamic disaster development situation, the online warning and alarm-removing of mine dynamic disaster are realized.

Description

technical field [0001] The invention belongs to the technical field of safety production, and in particular relates to a dynamic disaster modal early warning method based on real-time monitoring data. Background technique [0002] Mine dynamic disasters, including rock bursts (rock bursts), coal and gas outbursts, and water inrush and permeation, are all major mine disasters. Once such disasters occur, they will cause heavy losses to the lives and properties of mines. Therefore, the advance prediction, forecast and early warning of mine dynamic disasters are very important. [0003] In the prior art, for mine dynamic disasters such as coal and gas outburst, rock burst, water inrush and water inrush, it is possible to install microseismic monitoring, in-situ stress detection, electromagnetic radiation monitoring, acoustic emission monitoring, gas outflow monitoring, and water inflow monitoring. , roadway displacement monitoring, bolt resistance monitoring, support resistance...
