| Abstract: | According to the characteristics of the big dip angle of the fully mechanized caving face of Huafeng Mine, this paper introduces the synthetic technical measure to forecast and prevent the coal seam from spontaneous combustion. Monitoring the carbon monoxide concentration in the mine goaf, analyzing the index of self-ignition gas and locating the abnormal point of the coal oxidation are the main forecasting measures. The main preventing measures are pouring in nitrogen, grouting and infusion. In addition, w... |
