Safety of nanometer powder control technology-based on mine gas explosion.

Due to the rapid development of China and the increasing demand for various minerals, the accidents of mine operations have occurred frequently in recent years, which have caused a huge obstacle to the safety of the people's lives and the prosperity and prosperity of the country. Not to be ignored, the response is also imminent. Based on the above background, this paper aims to study the safety of nano-material powder control technology on mine gas explosion suppression. In order to further analyze the influence of nanomaterials on explosion suppression and the improvement of safety performance, the flame propagation and pressure characteristic parameters of gas explosion were selected to evaluate the safety performance. In this paper, nano-calcium carbonate and nano-silica are selected for explosion suppression experiments. According to the gas explosion theory, the smaller the particle size of the powder, the better the explosion suppression effect. Silicon oxide's small size effect, interface effect, photoelectric characteristics, etc., enhance the powder's anti-explosion performance. In the experiment, by adding powder, it was verified that the safety of nano-powder control technology for gas explosion suppression was improved. This article combines powder control technology with nano-materials, making full use of the powder properties of nano-materials, and studying their improvement of the safety performance of gas explosion suppression.
