煤矿甲烷检测仪器按工作原理分主要有三种—热催化原理、光干涉原理及热导原理。煤矿甲烷测定仪型式大致可分为四种:携带式检测仪、局部地区检测警报仪、机载式检测仪及远距离检测(遥测)系统。下面叙述各种原理、型式的煤矿甲烷检测仪器的现状和发展方向。
Coal mine methane detection instrumentation according to the principle of three main points - thermal catalytic principle, light interference principle and thermal conductivity principle. Coal mine methane detector type can be broadly divided into four types: portable detector, local area detection alarm, airborne detector and remote detection (telemetry) system. The following describes the principles and types of coal mine methane detection equipment status and direction of development.
