摘　　要：通过研究正压供气(空气或氮气)测定煤中碳酸盐二氧化碳的试验条件,确定了正压供气实验装置及实验步骤。实验证明,用正压供气测定方法与现行负压供气测定方法结果间无显著性差异,测定结果准确可靠,该2种方法可相互替代。正压供气测定煤中碳酸盐二氧化碳的方法改变了传统测定方法在实验过程中倒吸以及水资源浪费等现象,从而使该项检测更加节能、环保。The positive pressure gas supply apparatus and experimental procedure were determined by exploring the experimental conditions of determining the carbon dioxide content in the mineral carbonates of coal by positive pressure gas（air or nitrogen） supply system.There were no significant differences in the results of the determination methods between the positive pressure gas supply system and the current negative one,and results of both tests are accurate and reliable,which are showed by the experiments,therefore these two methods can replace each other.The positive pressure gas supply determination method can eliminate the disadvantages of inverse suction and wasting water in the traditional method,thus make the testing process more energy-saving and more environmental friendly.
