In order to prediction the working face's outburst danger more convenient and quickly, a new model of gas outburst parameters test-ing instrument is developed based on the coal cuttings desorption instrument of MD-2 model and the multistage flow meter of ZLD-2 model. The new instrudent can measure the coal drillings' gas desorption index△h2 and initial velocity of gas emission q. The new instrument has a wide range of promotional value as its structure is compact and it is convenient and accurate when using.
