Embodiment Construction

[0027] The invention discloses a method for automatic regional early warning of mine disasters based on microseismic information. By installing a microseismic monitoring system inside the target area, the occurrence time information, energy information, coordinate information, and magnitude information. Then, according to the collected occurrence time information, energy information, coordinate information, magnitude information and preset partition parameters of the several microseismic events, the three-dimensional partitioning of the several microseismic events is carried out. And every predetermined time interval, within the set time window, the microseismic activity characteristic value, microseismic intensity characteristic value, magnitude frequency distribution characteristic, and microseismic activity rate characteristic value of the microseismic event in each partition after the three-dimensional partitioning are performed , magnitude-frequency curve deviation degree...

Abstract

The invention discloses a method for mine disaster automatic zoning and early warning based on microseismic information, and belongs to the technical field of microseismic early warning. The method includes the steps that microseismic data are collected through a microseismic monitoring system, microseismic data include occurrence time information, energy information, coordinate information and magnitude information of a plurality of microseismic events; according to the microseismic data and preset zoning parameters, the microseismic events are subjected to three-dimensional zoning; at everypredetermined time interval, in a set time window, microseismic activity characteristic values, microseismic intensity characteristic values, magnitude frequency distribution characteristics, microseismic activity rate characteristic values, magnitude frequency curve deviation degree indexes and energy release change models of the microseismic events in each zoning are statistically analyzed correspondingly to obtain statistic data to plot, an itemized rating scale and a preset single score threshold or multiple total score threshold are developed to conduct zoning rating and early warning toa target zone. The method for mine disaster automatic zoning and early warning based on the microseismic information achieves the technical effects that safety is improved, operation is convenient, and the early warning effect is improved.

Description

technical field [0001] The invention belongs to the technical field of microseismic early warning, in particular to a method for automatic zoned early warning of mine disasters based on microseismic information. Background technique [0002] In the mining activities of ore deposits, the mine geological disasters caused by the destruction of a large number of mining shafts and the deformation of rock and soil, as well as the serious changes in the geological, hydrogeological conditions and natural environment of the mining area will endanger the safety of human life and property, and damage mining engineering equipment and mining areas. Resources and environment, disasters affecting mining production. Microseisms are tiny vibrations produced by rock fractures or fluid disturbances. [0003] For the existing technology of mine disaster early warning based on microseismic information, personnel are usually stationed on the site for a long time to observe and record, and analyz...
