Embodiment Construction

[0029] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as there is no conflict with each other.

[0031] It is very necessary to monitor landslide accidents in places where landslide accidents are likely to occur due to the storage of loose accumulations, such as dump sites. Taking the dump site as an example, in the prior art, the landslide accident in the dump site There are very few studies on monitori...

Abstract

The invention provides a collapse accident analysis model construction method and system and a collapse accident early warning method and system. The collapse accident analysis model construction method comprises: acquiring historical collapse monitoring data of all preset areas; extracting at least one characteristic infrasonic wave signal related to each collapse accident from the historical collapse monitoring data; and establishing a collapse accident analysis model according to the corresponding relationship between each characteristic infrasonic wave signal and each development stage ofthe collapse accident. Infrasonic wave signals generated during operation of loose accumulation bodies prone to collapse accidents are analyzed, time-varying characteristics of the characteristic infrasonic wave signals are determined, then the corresponding relation between the time-varying characteristics and each development stage of the loose accumulation body collapse accident is determined,the collapse accident analysis model is established, the model can visually reflect the relation between each development stage of the collapse accident and the time-varying characteristics, and a basis is provided for subsequent monitoring and early warning of the loose accumulation body collapse accident.

Description

technical field [0001] The invention relates to the field of mine safety, in particular to a method and system for building an analysis model of a landslide accident and an early warning method and system for a landslide accident. Background technique [0002] Today, the number and scale of loose accumulations formed by mine engineering construction are increasing year by year. Sliding accidents of loose accumulations that are prone to landslide accidents, such as landslide accidents in dumps, once they occur, often cause mass casualties and serious accidents that cause large-scale environmental damage. It is particularly important to carry out effective monitoring and early warning of slump accidents in loose accumulations that are prone to slump accidents. [0003] Infrasound is a sound wave with a frequency of 0-20Hz. Due to its small attenuation, strong penetrating power, and long propagation distance, infrasound is widely used in the monitoring of disasters such as ear...
