波兰目前几乎所有瓦斯矿井都有井下环境监测系统,利用遥测技术在地面对井下环境进行连续集中监视。波兰的煤矿安全规程对采用或不采用遥测系统的矿井风流中允许的沼气浓度有不同的规定。如工作面进风和回风中的沼气浓度,没有遥测系统的规定为0.5%和1.0%,有遥测系统的则为1.0%和1.5%.采用环境监测系统可大大提高煤炭产量。
At present, almost all gas mines in Poland have a downhole environment monitoring system that uses telemetry to continuously monitor the downhole environment on the ground. The coal mine safety regulations in Poland have different regulations on the biogas concentrations allowed in the wind flow of mines with and without telemetry systems. Such as the face into the wind and return air in the biogas concentration, no telemetry system provisions of 0.5% and 1.0%, while the telemetry system was 1.0% and 1.5%. The use of environmental monitoring system can greatly increase coal production.
