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.

Spontaneous combustion of the coal mine goaf is one of the main disasters in the coal mine. The detection technology based on symbolic gas is the main means to realize the spontaneous combustion prediction of the coal mine goaf, and ethylene gas is an important symbol gas of .

In this work a novel monitoring method was developed to measure the underground stray current in coal mine with fiber current sensing technique. According to the theory of optical fiber current sensor based on Faraday magnetooptic effect, a fiber sensing system was designed and the relative experiments with current generator simulating stray current were completed.

An investigation into the requirements and fire test performance of conveyor belts intended for use in underground coal mines was conduted. The aim of this study was to develop recommendations for the Mine Safety and Health Administration (MSHA) on a test method suitable for measuring the fire hazard potential of a conveyor belt in a coal mine environment.
