Safe Mining of extremely Thick Seam with Spontaneous Combustion

摘要

On the basis of in-situ measurements of three zones of spontaneous combustion extremely thick seam of QianQiu coal mine of Yi Ma Coal Administration, initial prevention spontaneous combustion methods for safe mining of 181 working face are proposed. After analysis actual situation and existing condition of 181 working face of QianQiu coal mine of Yi Ma Coal Administration, practical prevention spontaneous combustion measurements are concluded and also proved to be successful by the practice production of 181 working face. So the practical prevention spontaneous combustion measurements is a good method to mine extremely thick seam with spontaneous combustion and other spontaneous combustion thick seam can be extracted safely by the same way.
