一氧化碳(以下均写其分子式 CO)是一种剧毒气体,在许多厂矿企业,及时监测CO 在大气中的浓度,对保障职工身体健康具有重要意义。我国《煤矿安全规程》规定井下空气中 CO 浓度不得超过24ppm。在煤矿井下煤自然发火过程中要产生大量的 CO,矿井风流中 CO 浓度的增大是煤自燃的主要征兆之一。矿井通风安全和救护人员在预测和处理火灾事故中,都需要及时测定 CO 的浓度。因此,及时测定 CO 浓度,对煤矿安全生产具有重要意义。
Carbon monoxide (CO) is a highly toxic gas. In many factories and mines, the timely monitoring of the CO concentration in the atmosphere is of great importance to ensuring the health of workers and staff. China’s “Coal Mine Safety Regulations” provides that the concentration of CO in the air below the mine should not exceed 24ppm. In coal mine spontaneous combustion process to produce large amounts of CO, mine air flow in the concentration of CO is one of the main signs of spontaneous combustion of coal. Mine ventilation safety and rescue personnel in the prediction and treatment of fire accidents, the need for timely determination of CO concentration. Therefore, the timely determination of CO concentration is of great significance to coal mine safety.
