摘　　要：随着地震勘探技术的发展,煤田地震勘探也越来越多的采用高密度及大道数的采集方法,对于野外资料的品质也要求越来越高。为了在提高采集速度的同时,对采集的地震数据进行实时质量监控,以确保资料质量。本文探讨了利用地震采集实时监控软件,通过网络与采集仪器建立连接,实时地对地震采集的能量、频率、异常道、采集参数和环境噪音等属性进行分析与评价,对有问题单炮进行报警提示,达到了实时监控的目的。本文以煤田地面三维地震勘探项目为支撑,验证了实时监控对于煤田地震勘探数据采集的重要性,同时对监控数据进行了统计分析,圈定了工区单炮的属性分布图及工区异常单炮的分布图。With the development of seismic exploration technology, more and more high-density and large-channel acquisition methods are used in coalfield seismic exploration, and the quality of field data is also required to be higher and higher. We need to improve the acquisition speed, and the real-time quality monitoring of the collected seismic data need to be carried out to ensure the quality of the data. This paper discussed that analysis and evaluation of energy, frequency,abnormal trace, acquisition parameters and ambient noise of seismic acquisition were carried out in real-time, and alarm prompt was carried out for problematic single shot, based on use of seismic acquisition real-time monitoring software,connecting the acquisition equipment through network, which achieved the purpose of real-time monitoring. Based on the coalfield ground three dimensional seismic exploration project, this paper verified the importance of real-time monitoring for coalfield seismic exploration data acquisition. At the same time, the monitoring data were statistically analyzed, and the attribute distribution map of single shot and the distribution map of abnormal single shot in the working area were delineated.
