All-round distributed monitoring system and method for preventing coal gangue from spontaneous combustion

Abstract

The invention discloses an all-round distributed monitoring system and method for preventing spontaneous combustion of coal gangue. By constructing an all-round distributed monitoring system, the internal temperature of coal gangue can be monitored in real time, and corresponding technical parameters can be obtained to prevent coal gangue from spontaneous combustion. . The present invention utilizes a new type of sensing testing technology (distributed optical fiber sensing testing technology) to improve the testing device and obtain a complete set of testing methods for preventing coal gangue from spontaneous combustion. Provide better security.

Description

technical field [0001] The invention relates to the technical field of monitoring of coal mines and coal gangue heaps, in particular to an all-round distributed monitoring method for preventing spontaneous combustion of coal gangue heaps. Background technique [0002] Black rock, which is lower in carbon and harder than coal, accounts for about one-tenth of all coal produced annually. According to incomplete statistics, there are more than 1,500 coal gangue hills in state-owned coal mines in China, with an accumulation of more than 3 billion tons, accounting for more than 40% of my country's total industrial solid waste discharge. At present, with the improvement of fully mechanized mining and the large-scale utilization of coal resources, the production of coal gangue is increasing year by year. In order to save land utilization, coal gangue is generally piled up into mountains, but long-term stacking and oxidation will make The internal temperature of coal gangue rises sh...

AI Technical Summary

Problems solved by technology

At present, the conventional temperature measurement technology mostly adopts infrared thermal imaging technology, which mainly has the following problems in the implementation process: 1. Infrared thermal imaging technology is sensitive and accurate to the surface temperature perception, and it is difficult to effectively capture the internal deep temperature; 2. 1. Coal gangue hills are generally large, and the use of infrared thermal technology to detect temperature is time-consuming and labor-intensive; 3. It is difficult to accurately determine the abnormal location for the perceived temperature abnormal area; 4. Harmful gases released by coal gangue hills will affect the health of operators. Bring certain damage; 5. Cannot monitor in real time and grasp the temperature distribution in an all-round way
