Abstract:
Due to the concealment of the fire source in the gob, the fire prevention and extinguishing work in the gob is facing great difficulties. This study is made in order to realize the real-time monitoring of gob temperature and the accurate positioning of high temperature area, so that the fire prevention and extinguishing work in gob can be targeted. In this study, the previously developed COMBUSS-3D software was used to predict the high temperature area in the gob of 85001 working face of Yangmeiwu Coal Mine and II830 working face of Zhuxianzhuang Coal Mine in China, and the continuous monitoring system of gob temperature was independently developed to realize the real-time monitoring of gob temperature, achieving the purpose of accurate positioning of high temperature area in gob. The results show that the high temperature area of the gob of 85001 working face of Yangmeiwu Coal Mine was in the range of approximate circle centered on the point (36.6, 30), and the maximum temperature was 31.7 °C. The high temperature area of the gob of II830 working face in Zhuxianzhuang Coal Mine presented an approximate ellipse centered on (28.2, 25), and the long axis was parallel to the working face, and the maximum temperature was 43.9 °C. The research results are expected to provide reference for the early prediction of spontaneous combustion in gob.

01:13Equipments Used to Measure Body Temperature
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
01:14Assessing Body Temperature - Oral
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
