Correlations among free radicals, apparent activation energy, and functional groups during low-temperature oxidation of Jurassic coal in Northern Shaanxi were investigated by examining three samples collected from the Ningtiaota, Jianxin, Shigetai mines. Free radical concentrations at less than 120 °C electron spin resonance experiments while thermogravimetric conducted to analyze energies. In addition, Fourier transform infrared spectroscopy was employed study spectrum generated coal. The...
To understand the effects of water immersion on spontaneous combustion low-rank bituminous coal, and underlying mechanism, pore size distributions active functional groups water-immersed coal samples were studied. Characterization data acquired by liquid nitrogen adsorption Fourier transform infrared spectroscopy. The behaviors experimental assessed based oxidation kinetics obtained using a programmable temperature device. Water promotes development enhances activity groups, which in turn...
This paper has tested the CO source of 2521 fully mechanized face through SF6 gas and contrapuntally made comprehensive control technology based on loess cover, isolation grouting slurry. In fire extinguishing process, is used to prevent spontaneous combustion area from enlarging, cover reduces air leakage in Coal Gangue Heaps, borehole trenching reduce heat quantity area. According detection field parameters, above technical measures have controlled areas coal gangue Baijigou Mine.
To reveal the influence of pre-oxidation time on coal spontaneous combustion behaviors, temperature-programmed experiments were carried out to analyze kinetics characteristics primary and secondary from macro viewpoint. By growth-rate analysis gaseous compounds, critical temperature raw (Y0) was 70°C. At temperature, isothermal oxidation performed for 2 h, 4 6 8 processed samples named Y2, Y4, Y6, Y8. It found that changing trend CO concentration increased at first then decreased with...
Leisure-time physical activity (LTPA) has been well documented as having substantial health benefits. The 2014 Chinese Fitness Survey Report stated that a lack of (PA) spaces is the most important non-human factor, leading to 10% leisure-time inactivity in people aged 20 and above. We investigated provision sports venues China discussed development national fitness policies context promoting LTPA public health. analyzed information from China’s recent sport venue census, Sixth National...
Community emergency management is directly related to the safety of people's lives and properties concerned with economic development social stability. This paper established an evaluation model community capacity from perspective resilience based on hierarchical analysis (AHP) distance between superior inferior solutions (TOPSIS). In terms infrastructure resilience, organizational risk, hidden danger management, material security, force construction, literacy, index system resilient were...
Oxygen concentration of the oxidation combustion zone in coalfield fire and coal spontaneous dangerous area mine such as goaf sealed are all lower than that normal atmospheric. Also, these two areas have characteristics high temperature. Therefore, this paper, XKGW-1 type temperature experiment device had been designed manufactured independently. It was employed to investigate entire process by using test method programmed. Five oxygen concentrations, 21, 17, 9, 5, 3 vol%, were tested,...
