Tube System Application and Research in the Division of the Fully-mechanized Caving Goaf

摘要

Fire protection in goaf of fully mechanized caving face is always a pain points of "one ventilation and three preventions",according to spontaneous combustion "three belts" theory and division standard in goaf,combined with tube monitoring "three zones" observation data of 6 coal of 107 in Acid Sting Ditch fully-mechanized caving,determining the scope of spontaneous combustion "three-zone",and provides the scientific basis for the following against fire fighting work,thereby preventing the occurrence of fire,to maintain the normal production of working face.
