Monitoring and early warning device and method for spontaneous explosion of vulcanized mine explosives

Abstract

The invention provides a monitoring and early warning device and method for spontaneous explosion of vulcanized mine explosives. The monitoring and early warning device comprises a data analysis device, a sensor assembly, a fan and an audible and visual alarm, wherein the sensor assembly, the fan and the audible and visual alarm are connected with the data processing device. The wind power outputend of the fan is positioned in a blast hole. The sensor assembly comprises an infrared temperature measurement sensor module and an air pressure sensor module which are arranged in the blast hole. The data analysis device monitors environmental parameters in the blast hole through the sensor assembly and conducts safety evaluation on the blast hole according to environmental parameter data, and when the evaluation result shows that the spontaneous explosion risk exists, a single-chip microcomputer controls the fan and the audible and visual alarm to conduct blast hole ventilation and heat dissipation and send out audible and visual alarm information. According to the device, the spontaneous explosion risk of the explosives in the blast holes of the vulcanized mine can be evaluated througha plurality of environmental factors.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a self-detonation monitoring and early warning device and method for sulfide mine explosives. Background technique [0002] Sulfide ore is a collection of various sulfur-containing metals, and its main component is pyrite. Pyrite is an important sulfur ore resource for industrial development and utilization. It contains three minerals with the same composition: pyrite, marcasite and pyrrhotite. With the recovery and development of the national economy, the demand for sulfur ore resources in my country is increasing year by year, and the shallow mineral resources are becoming increasingly exhausted. At the same time, there are currently more than 160 mines in my country with a proven value of more than 1 trillion yuan in deep mines. Deep mining will be inevitable for the development of the mining industry. [0003] Explosive self-explosion accident is one of the serious disasters...

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
