Fully Mechanized Coal Caving Face Zaoquan Spontaneous Combustion Prevention Research

In recent years, the mechanized caving face easy significantly increased the number of spontaneous coal seam fires in the recovery process, the mine fire seriously affected the normal production of the coal mine. The2coal God Ning Coal Limited Zaoquan mine belonging to the spontaneous combustion seam spontaneous combustion tendency. Accurate determination of the goaf of coal spontaneous combustion "three zones", given the face the minimum stoping security propulsion speed, to grasp fully mechanized caving face Seam Spontaneous Combustion law, has important implications for ore Zaoquan’s normal production.Papers using theoretical analysis and numerical simulation as well as on-site determination of combination, spontaneous combustion seam fully mechanized caving face of Zaoquan coal mine12207Safe Mining technology to do some research. Analysis of fully mechanized coal caving face Zaoquan spontaneous combustion seam in Gobs in the influencing factors of coal spontaneous combustion, summarized the Zaoquan fully mechanized coal caving face Spontaneous Combustion Coal Seam Spontaneous Combustion. Goaf through computer simulation to determine the distribution of the "three zones" and simulation of goaf optimize the amount of wind "with" changes; scene through the beam pipe detection to identify the goaf spontaneous combustion "three zones" proposed the return safely Bian Face minimum speed of advancement, and the measurement results of the computer simulation comparison, the results of the simulation and the measurement results is basically the same. Finally, the coal mine Zaoquan spontaneous combustion seam security measures stoping prevention technology.
