在报告中阐述了根据氧化物的分析,断定初期内因火灾的方法。分析是用安装在地面的仪器进行的,矿井空气试样是沿巷道敷设的专用管子从井下提取的。提取空气试样采用一般的薄膜泵和专设的管子。仪器能测定矿井空气中的一氧化碳。这种装置的缺点是采取空气试样和测定气体含量所需的时间比较长(从矿井最远的地方要五个小时)。
In the report, I elaborated on the method of determining the initial internal cause of fire based on the analysis of oxides. The analysis was carried out with ground-mounted instruments, and the mine air samples were taken downhole with special pipes laid along the roadway. Extraction of air samples using a common membrane pump and dedicated tube. The instrument measures the carbon monoxide in the mine air. The disadvantage of this device is the relatively long time it takes to take an air sample and determine the gas content (five hours from the furthest point of the mine).
