| Abstract: | The noises source of high power diesel engines in the mine was analyzed and the noises from high power diesel engines in the mine were classified.Some control measures are put forward based on analysis results of noises from exhaust,fan combustion,mechanics,structural response and surface,etc.The results indicate that sound power level(PWL) of the engine is reduced by 12.8dB(A) with proposed measures,which makes it lower than the value of the national standard.So the measures are effective and available. |
