A multi-parameter local danger area identification and early warning method for mine disasters

Abstract

The invention relates to the field of mine dynamic disaster monitoring pre-warning, and aims to provide an identifying and pre-warning method of a mine disaster multi-parameter local danger zone. Theposition and the danger level of the local danger zone can be accurately identified, a mine can be guided in a targeted mode for disaster prevention, and the site requirements for all mines can be met. The pre-warning method comprises the steps that 1, spatial positioning is conducted on mine disaster monitoring points; 2, initial risk indexes I<single point initialization> (I<single point initialization> is larger than or equal to zero and smaller than or equal to one) of all the monitoring points are obtained; 3, conditions of other monitoring points around all the monitoring points are retrieved; 4, the initial risk indexes of the monitoring points are corrected; and 5, the position and the risk level of the local danger zone are obtained. According to the identifying pre-warning methodof the mine disaster multi-parameter local danger zone, the problem that the mine can not be guided in a targeted mode for disaster prevention due to the fact that the position and the risk level ofthe local danger zone can not be identified accurately through an existing pre-warning method is solved.

Description

Technical field [0001] The invention relates to the technical field of monitoring and early warning of mine dynamic disasters, in particular to a method for identifying and early warning of multi-parameter local dangerous areas of mine disasters. Background technique [0002] Mine dynamic disaster is one of the main factors affecting the safe and healthy development of the mining industry around the world. It has the characteristics of strong suddenness, multiple influencing factors, and strong chance. It is extremely destructive. Once such a disaster occurs, it will cause mines. Significant loss of life and property. Therefore, early monitoring and early warning of mine dynamic disasters is an important measure to prevent the occurrence of major mine dynamic disaster accidents. Mine dynamic disasters include rock bursts (rock bursts) induced by mining and underground engineering activities, coal and gas outbursts, roof collapse, water inrush, etc. The mechanism of dynamic disas...

AI Technical Summary

Problems solved by technology

[0006] For this reason, the technical problem to be solved by the present invention is that the mine dynamic disaster monitoring and early warning method of the prior art cannot accurately judge the location and danger level of the local danger zone, the early warning effect is relatively poor, and it cannot guide the mine to carry out disaster protection in a targeted manner. To provide a mine disaster multi-parameter local danger area identification and early warning system that can accurately identify the location and danger level of the local danger area, has a good early warning effect, can guide the mine to carry out disaster protection in a targeted manner, and can meet the needs of each mine site. method
