摘　　要：针对地面井瓦斯抽采监控计量存在可靠性差、精确度低的问题,通过对抽采检测、野外自供电、分布式测点数据采集、计量监控装置等技术及工艺的研究,形成了一套地面井瓦斯抽采单独计量监测系统,为地面井实时在线监测提供了整套技术与装备,提高了地面井计量的精确度;同时将地面井瓦斯抽采数据与井下监控系统数据实时结合在一起,实现了矿井抽采的安全和有效监控。In view of the problems of poor reliability and low accuracy in the monitoring and measurement of gas drainage in surface wells, a set of separate measurement and monitoring system for gas drainage in surface wells has been formed through the research on extraction detection, field self-powered supply, distributed measurement point data acquisition, measurement and monitoring device. The system provides a complete set of technology and equipment for real-time on-line monitoring of surface wells, and improves the accuracy of surface well measurement. At the same time, the surface well gas extraction data is combined with the downhole monitoring system data in real time, which realizes the safety and effective monitoring of mine drainage.
