摘要: 为了防止煤层瓦斯抽采钻孔时因煤粉自燃而导致一氧化碳浓度过高和瓦斯爆炸，设计了矿用打钻防着火安全保护装置。该装置通过传感器监测一氧化碳和瓦斯浓度，采用单片机实现高压风和压力水的自动转换控制。现场试验显示，在打钻期间钻孔煤粉发生自燃的情况下，该装置可以实现高压风和压力水的自动转换，及时将钻孔内燃烧的煤粉熄灭。

Abstract: In order to prevent high concentration of CO and gas explosion caused by spontaneous combustion of coal during drilling for coal seam gas drainage, the paper proposed a design scheme of mine-used safety protection device for preventing fire during drilling. The device monitors concentration of CO and gas by sensors, and uses single-chip microcompute to achieve automatic switching of high-pressure air and pressure water. Field tests show that the device can realize automatic switching of high-pressure air and pressure water and crush out burning coal when spontaneous combustion occurs during drilling.
