Sulfide mine explosive self-explosion monitoring and early warning device and method

Abstract

The present invention proposes a self-detonation monitoring and early warning device and method for sulfide mine explosives. The monitoring and early warning device includes a data analysis device, a sensor assembly connected to the data processing device, a fan, and an audible and visual alarm; the wind output end of the fan is located in the blasthole The sensor assembly includes an infrared temperature measurement sensor module and an air pressure sensor module located in the blasthole; the data analysis device monitors the environmental parameters inside the blasthole through the sensor assembly, and performs a safety assessment on the blasthole according to the environmental parameter data , when the evaluation result shows that there is a risk of self-explosion, the single-chip microcomputer controls the fan and the sound and light alarm to ventilate and dissipate the blast hole and send out sound and light alarm information respectively; Risks are assessed.

Description

Technical field [0001] Technical Field The present invention relates to mining, in particular in sulfide ores explosives blew monitoring and warning apparatus and method. Background technique [0002] Sulfide ore more sulfur-containing aggregate is a metal material, whose main component is pyrite. Pyrite important industrial exploitation Sulfur resources, comprising pyrite, marcasite same three components and pyrrhotite minerals. With the restoration and development of the national economy, my country's demand for sulfur mineral resources increased year by year, shallow mineral resources are depleting. At the same time, our existing proven in more than 160 deep mines worth more than more than one trillion yuan, deep mining will be the inevitable development of the mining industry. [0003] Explosives blew accident is one of vulcanized deep mines may face serious disasters. Sulfide ore mining operations in a borehole is usually filled Blasting explosives, blast hole temperature is...

AI Technical Summary

Problems solved by technology

In sulfide ore mining operations, explosives are usually filled in blastholes for blasting mining. The temperature in the blasthole is mainly affected by the three heat sources of sulfide ore oxidation heat generation, cement hydration heat generation, and geothermal heat. When the heat accumulation in the blasthole reaches the critical deflagration of explosives When the temperature is lowered, it can induce the explosive to explode in advance, seriously affecting the safe mining of ore
