| Abstract: | The spontaneous combustion tendentiousness of 5# coal seam is measured,the emission and location of float coal and condition of air leakage in goaf are measured and analyzed.This thesis sum up the reasons for spontaneous combustion in goaf and put forward comprehensive measures to expounds the application about preventing and extinguishing mire fire.The comprehensive measures include prediction of spontaneous combustion,plugging up the leakage flow,pressing MEA,injecting nitrogen,balanced-pressure,logical mining speed at working face,stuffing the crack on the earth's surface.The effects of these technical measures have been achieved certain effects in practice. |
