一、引言在井下某些地方安装连续测量瓦斯的传感器并借助信号调制电子设备和信息传输系统通往地面的监视中心,实行全矿瓦斯遥测,逐步代替人工巡回检测,这是目前提高矿井安全的有效方法。但这种电子遥测系统的所有设备必需首先保证安全性能,使其完全符合《煤矿安全规程》的规定。现在检测甲烷常用的催化、热导
I. INTRODUCTION In some places in the underground, sensors for continuously measuring gas are installed and the monitoring center which leads to the ground by means of signal modulation electronic equipment and information transmission system is implemented. The whole mine gas telemetry is implemented and the manual tour inspection is gradually replaced. At present, the mine safety is improved Useful ways. However, all the equipment of such electronic telemetry system must first ensure the safety performance so that it fully complies with the requirements of “Coal Mine Safety Regulations”. Methane now commonly used in the detection of catalysis, thermal conductivity
