Study On Prevention And Control Technology Of Coal Spontaneous Combustion In Dongtan Coal Mine

Coal mine fire is one of the five major disasters,in case of mine fire,the fire development speed,control more complex,affecting a wide range of easy to cause casualties and property losses,and even give rise to dust,gas explosions,causing a greater disaster.As the Dongtan Coal Mine spontaneous combustion with coal is dangerous,spontaneous combustion of coal shorter,the actual shortest coal spontaneous combustion was 18 days.This article describes the coal mine fire extinguishing technology application in Dongtan Coal Mine,points out based on system security,strengthening the application of basic research,breakthroughs in key technologies,design the best anti-extinguishing.Combined with resolving the problem of Fire prevention work in 1303 fully mechanized waorking face,Applicating grouting colloid with static pressure and high power retarding foam to prevente and control of mine spontaneous combustion in goaf,and made sound effects.On the prevention and control of coal spontaneous fire,no one method is universal.usually several fire extinguishing technology and materials is integrated to get the effect,the key of achieving better control effect is to analyze the situation of spontaneous combustion of coal,position and according to the actual conditions,choosing the right technology and means.
