Method and device for monitoring range of heat abnormality in mining area

Abstract

The invention discloses a method and device for monitoring a range of heat abnormality in a mining area. The method for monitoring the range of heat abnormality of the mining area comprises the steps of: obtaining a thermal infrared image in a target area; converting grey information in the thermal infrared image into temperature information; and determining the range of thermal abnormality in the target area according to the temperature information and a pre-set temperature threshold. According to the invention, as the grey information in the thermal infrared image is converted into the temperature information, the surface temperature of the target area can be determined accurately; and as the surface temperature is then compared with the pre-set temperature, the area with the surface temperature higher than the pre-set temperature can be determined to have the heat abnormality phenomenon. Therefore, the problem that the range of the heat abnormality cannot be monitored accurately in the prior art is solved, and furthermore the effects of monitoring the range of heat abnormality in the mining area rapidly and accurately are realized.

Description

technical field [0001] The invention relates to the field of surveying, in particular to a method and device for monitoring a thermal anomaly range in a mining area. Background technique [0002] The solid waste discharged during coal production and processing has caused environmental pollution in mining areas and damage to the ecological environment. Coal gangue is the main by-product of coal processing, accounting for about 25% of my country's industrial solid waste emissions. As the world's largest coal producer and consumer, my country's coal gangue has accumulated more than 5 billion tons, and its total amount is still increasing at a rate of 300-350 million tons per year. [0003] Due to the long-term stacking of gangue in the open air, the heat inside the gangue gradually accumulates. When the temperature reaches the ignition point, the residual coal and other combustibles in the gangue can spontaneously ignite. There are more than 1,500 large and small coal gangue ...
