井下煤矿瓦斯含量检测控制系统

Monitor and Control System of Coal Mine Gas Content

本文论述了瓦斯含量监控系统的组成和检测原理,考虑系统的工作环境的特殊性并对其进行实时监控,能够实现瓦斯浓度超限报警系统外,基于有时候井下瓦斯浓度会激增,短时间内增长得很快,还特别设置了瓦斯增长率报警信号,这为预防和减小灾害损失提供了有效可靠的科学手段。

This article discusses the principle and composition of the gas content monitor and control system. Considering the special nature of the working environment , real-time monitoring can implement over-limit warning of gas density. In case underground gas concentration will surge in growth in a short period of time, a special gas rate alarm signal is set up to provide scientific ways to prevent and reduce disaster losses.
