摘要
在施工瓦斯抽采钻孔时,为防止因钻孔施工着火引起一氧化碳浓度过高和瓦斯超限,设计并实践应用了矿用钻孔施工防着火及瓦斯超限安全保护装置,该装置通过传感器监测一氧化碳和瓦斯数据,当出现一氧化碳超限信号时,通过电子阀实现高压风和高压水的自动转换控制。
when drilling in the construction of gas extraction, to prevent high carbon monoxide concentrations caused by drilling is on fire and gas overrun, design and application of the mine drilling on fire prevention and safety protection devices, roadway, the the device through the sensor monitoring data, carbon monoxide and gas when carbon monoxide overrun signal, through electronic valve to realize the automatic conversion of the control and use the high pressure water.
