Problems solved by technology

However, most of the above indicators only contain statistical features and lack obvious physical meaning. A small number of indicators with obvious physical meaning only stay in qualitative analysis, such as "abnormal rise of index curve", "abnormal decline", " Low Value Exception", "High Value Exception", etc.

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] A time-series monitoring and early warning method for rock burst, specifically a new short-term quantitative time-series monitoring and early warning index, which can reflect the shock hazard state in the current underground monitoring area in real time, and the index has clear physical meaning, strong operability, and is suitable for Realize intelligent real-time early warning through programming.

[0034] The theoretical basis of the present invention is described below first from the acoustic emission phenomenon under the laboratory sample scale and the microseismic phenomenon under the mine scale; secondly, the calculation method of each parameter in the impact deformation energy warning index and index is proposed, and the physics of each representative has been clarified. significance; then construct the index discrimination criteria, and formulate the pre...

Abstract

The invention discloses a time-series monitoring and early warning method for rock burst, which comprises the following steps: (1) calculating the early warning index value Wε of impact deformation energy; (2) determining the danger level and the corresponding prevention and control of the danger level Countermeasures; the greater the impact deformation energy early warning index value Wε, the higher the risk level; (3) Risk release identification. The advantage of the present invention is that it can reflect in real time the impact danger state of the current monitoring area underground, guide the site to take corresponding prevention and control measures, and test the effect of the current pressure relief and crisis relief measures in real time. The early warning index proposed by the present invention also has clear physical meaning and is operable. It is strong and suitable for programming to realize the characteristics of intelligent real-time early warning.

Description

technical field [0001] The invention relates to a method for time-series monitoring and early warning of rock burst, which is a new index for short-term quantitative time-series monitoring and early warning. Background technique [0002] The monitoring and early warning of rock burst disasters is one of the world's difficult problems. So far, countries have not completely solved the accurate prediction and forecast of such disasters in time and place. Because of this, many rock burst accidents on the site have brought a huge threat to the safe mining of the working face and roadway excavation, and also caused huge economic losses to the mine. For example, in the 2011 "11·3" impact mine pressure accident at Yima Qianqiu Coal Mine in Henan Province, 75 miners were trapped, 67 were successfully rescued and 8 miners were killed; the "7·30" impact at Zhangshuanglou Coal Mine in Xuzhou, Jiangsu Province in 2011 Mine pressure accident, killing 6 miners; Sunjiawan Coal Mine 2005 "2...
