Abstract
This paper discusses the significance of pipeline gas drainage tester for coal mine safety production,analyzes the prob-lems existing in the use of similar products in coal mines.In accordance with the provisions of article 47 of the Detailed Rules for the Prevention and Control of Coal and Gas Outburst on drill hole measurement in pre-drainage coal seams,we have developed a port-able multi-parameter measuring instrument for gas drainage pipelines from three aspects:process technology,optimization al-gorithm and internal structure.This article provides a detailed introduction to the design scheme of the measuring instrument from key hardware aspects such as overall scheme and performance indicators,power supply and storage,as well as key software aspects such as data reception,storage protection,and flow calculation.Through extensive on-site testing and certification,the measuring in-strument has solved the problems of"slow measurement,inaccurate measurement,and heavy instrument"in the concentration and negative pressure of the pumping borehole,ensuring that the staff master the accuracy of the pre pumping borehole parameters.关键词
