Abstract
In recent years, coal mine safety is an urgent problem needs to be solved in China. The article takes into account the impact of the safety evaluation factors of traditional coal mines (taking the Bofang mine as an example), using information entropy to determine the index weight, and then applies unascertained measurement model evaluation to assess its security level. By Bofang mine empirical investigation and analysis, the results show that the unascertained measure model of traditional coal mine safety risk assessment is in line with reality, but also judges the results of a scientific and rational.
