Abstract

The invention discloses a monitoring system of an omnibearing distributed coal-gangue-mountain spontaneous combustion prevention and a method thereof. Through constructing an omnibearing distributed monitoring system, an internal temperature of a coal gangue mountain is monitored in real time, a corresponding technology parameter is acquired and coal-gangue spontaneous combustion is prevented. In the invention, through using a novel sensing test technology (a distributed fiber sensing test technology), a test device is improved and a set of complete coal-gangue-mountain spontaneous combustion prevention test method is acquired; and by using the acquired technology, good safety guarantee can be provided for aspects of coal-gangue spontaneous combustion prevention and fire extinguishing processing.

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...
