Development and Application of Portable Mining Vibration Recorder

Abstract:

t has been a bottleneck for the application of vibration-related techniques in the coal mine that the vibration data cannot be acquired due to lack of mining vibration instrument. This paper discussed the development of a portable mining vibration recorder, introduced its overall scheme, as well as its hardware and software design in detail. The developed recorder is a coal mine intrinsically safety instrument based on ARM system, with features of 4 channels analog input, 2GB large volume storage memory, 250kHz sampling frequency, no less than 3.5h full-payload continuous working time with battery supply, fitted to record and deposit the vibration signal of the equipment in atmospheres with methane and coal dust explosive mixture. The authors carried out a series of testing application in ChengZhuang coal mine. The experimental results show that the data acquired by the recorder is true and valid. Study provides an instrumental basis of apparatus to carry out the supervision of machine based on vibration detection in coal mine.
