为在黄铜矿山安全地进行爆破作业,必需有测定硫化矿尘爆炸的可靠方法。如果强烈的爆炸易于按照清晰的外部迹象(声响、冲击波及其他)识别,那么发觉微弱的爆炸(爆燃)就困难得多。因为,微弱的爆炸不伴生声效应或波效应。甚至当硫化矿尘爆燃很小时,工作面二氧化硫量也能超过允许标准的千百倍。因而,矿工就会直接受到中毒威胁。通常在爆破后于工作面取气体试样测定矿尘的爆燃。这种方法虽很可靠,但只有带呼吸器的矿山救护人员才能进行,因此,不经常采 For the safe operation of blasting at a chalcopyrite mine, there is a need for a reliable method of determining the explosion of sulphide mine dust. If a strong explosion is easily identified by clear external signs (sound, shock, and others), it is much more difficult to detect a faint explosion (deflagration). Because, weak explosion is not associated with acoustic or wave effects. Even when the deflagration of sulfide dust is very small, the amount of sulfur dioxide in the working surface can exceed the allowable standard by a hundredfold. Thus, miners will be directly threatened with poisoning. Usually after blasting gas samples taken from the face to measure deflagration mine dust. Although this method is very reliable, but only mine rescue workers with respirators to carry out, therefore, not often
