Analysis and Application of Coal Mine Gas Extraction Flow Detection Technology
The environment of coal mine gas extraction pipeline is very complicated.The accurate measurement of gas extraction pipeline flow parameters is a difficult problem in the industry,which restricts the reliable application of coal mine gas extraction monitoring system and the development of intelligent drainage monitoring.In this paper,through the comparison of the selection of gas extraction pipeline flowmeter and monitoring application analysis,an advanced flowmeter based on the circulated self-excited flow detection technology was adopted.Through application verification,it is shown that under the environmental conditions of heavy dust and water in gas extraction pipeline,the gas extraction pipeline flow index fully meets the requirements of coal mines.It provides a solid data basis for intelligent evaluation of coal mine gas extraction and gas prevention.
