Special Issue Information

Dear Colleagues,

Fire and explosion are the main types of disaster that occur in mines, including coal spontaneous combustion (internal fire), external fire, and gas (coal dust) explosion. Great progress has been made in coal spontaneous combustion prediction, fire-area detection, fire-control technology and materials, and standardization system construction. We now have a greater understanding of the disaster mechanism of explosion under the coexistence of gas, coal dust and fire, and the risk-assessment system and quantitative method of gas (coal dust) explosion. A lot of research work has been conducted in relation to the use of ventilation to prevent gas (coal dust) accumulation and overrun, which could effectively prevent such disasters. The major coal-producing countries, such as China, the USA and Australia, attached great importance to the research, development, and application of disaster emergency rescue technology and equipment in mines, and have made considerable progress in emergency communication, personnel positioning, remote detection in disaster areas, construction of escape routes, accident emergency and auxiliary decision-making, airflow regulation, and escape guidance after a disaster.

This Special Issue, “Mine Fires and Explosions”, aims to cover recent developments in occurrence mechanisms, new techniques and equipment, safety management and risk assessment, emergency rescue theories and technologies for the control of mine fires and explosions. Original research articles and reviews are welcome, and the submitted papers should clearly show novel contributions and innovative applications of how science can support any of the following fire-related topics (amongst others):

  • Mechanisms of mine fires and explosions and behavior modeling;
  • Application of new techniques and equipments for the control of mine fires and explosions;
  • Application of new materials (fire prevention, explosion suppression or dustproof material);
  • Numerical simulation of dust diffusion, gas migration or flame spread under coupling multi-physical fields;
  • Space-time evolution and their destructive effects of mine fires and explosions;
  • Closed-loop management model;
  • Real path and coupling effects;
  • Risk control with an accident chain;
  • Risk assessment;
  • Airflow regulation;
  • Assessment of emergency response capability.  

We look forward to receiving your contributions.

Studies show that accurate division of spontaneous combustion (SC) zones in the goaf and the determination of the prediction system of the SC index are of great significance to prevent spontaneous and unwanted combustions in the goaf. Aiming at resolving the problem of coal SC in the goaf of an “isolated-island” fully mechanized caving face, a multiphysics model coupled with gas flow field and gas concentration field was established in the present study. Taking the 8824 working face of Nanzhuang coal mine as the research object and the oxygen concentration as the division index, coal SC was simulated in the goaf. The obtained results show that the ranges of heat dissipation zone, oxidation zone, and the asphyxia zone on the air inlet side are around 0–107 m, 107–239 m, and beyond 239 m, respectively. Moreover, the ranges of the three zones on the return air side are 0–13 m, 13–189 m, and beyond 189 m, respectively. The ranges of the three zones in the middle of goaf are 0–52 m, 52–213 m, and beyond 213 m, respectively. The performed analyses demonstrate that the obtained simulation results are consistent with the experimental data. Meanwhile, the coal programmed temperature rise experiment was carried out to improve the prediction index gas system of SC. It was found that CO and C2H4 can be used as early warning indices of SC in the goaf, while C2H6, C3H8, and C2H4/C2H6 are auxiliary indices to master the coal SC. Full article

Due to high gas content and a low permeability coefficient in deep coal seam mining, the spontaneous combustion of coal around the wellbore can easily occur, leading to difficulties in extracting gas during the mining process. To determine the dangerous area around the borehole and conduct advanced prevention and control measures are the keys to preventing spontaneous combustion in boreholes. However, the dangerous area around the borehole is not clear, the sealing parameters lack scientific basis, and the key prevention and control measures are not clear, which have caused great harm to coal mines. This study took the 24,130 working face of Pingdingshan No. 10 Mine as an example, using numerical simulation, theoretical analysis, and field tests to classify the risks of studying the surrounding area of the wellbore. The dangerous area variations under different lengths of shotcrete in the roadway were analyzed, the optimal plugging parameters were studied, and the current “two plugs and one injection” plugging device was optimized. Based on the oxygen concentration and air leakage rate, a method was proposed to divide the dangerous area of fissure coal spontaneous combustion around the borehole induced by gas extraction. The dangerous area of spontaneous combustion around the borehole was defined as having an oxygen concentration larger than 7% and an air leakage rate less than 0.004 m/s. The comprehensive control measures of the grouting length at 2–4 m, hole-sealing parameter at 20-13 (hole-sealing depth 20 m, hole-sealing length 13 m) and the “two plugs, one injection and one row” device were determined.

The phenomenon of abnormal CO emergence occurred in a working face of Tangshan mine, and the CO source was analyzed from the two perspectives of CO detection method optimization and microstructure changes in the low-temperature environment of the coal body. Then, the critical index system was optimized. The CO identification tube test results and gas chromatograph test results are combined to derive a fitting formula, and the CO identification tube test results are used as the independent variable to obtain the gas chromatograph test results, which can effectively eliminate the error of small CO identification tube test results. The analysis of raw coal and coal samples heated by water bath at 30 °C, 40 °C, and 50 °C was carried out using low temperature liquid nitrogen adsorption and thermogravimetric and infrared spectroscopy experiments. It was found that the pore structure of the coal body developed as the temperature increased; the oxidation reaction occurred in the low-temperature state when heat was absorbed to produce CO. The thermal decomposition of carbonyl group was found to be the main source of CO. Finally, the index of spontaneous combustion of coal is optimized according to the temperature, and the index systems represented by O2/(CO2+CO), CH4 and CO2/CO were determined from 30~80 °C, 90~180 °C and 18~240 °C, respectively.
