摘　　要：为了更方便、快捷的预测采掘工作面的突出危险性,在MD-2型煤钻屑解吸仪和ZLD-2型钻孔多级流量计的基础上,研制了一种集钻屑瓦斯解吸指标△h2和钻孔瓦斯涌出初速度q测试于一体的新型瓦斯突出参数测定仪,仪器设计有喷咀转换阀,可快捷、准确的转换不同喷咀。该仪器具有结构紧凑、使用方便、测试准确等优点,在煤矿具有较大的推广价值。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.
