Mind wandering can cause workers to overlook safety hazards and delay making accurate operational decisions, ultimately raising the potential for accidents. However, there is relatively little research on the physiological characteristics of drilling workers during mind wandering. The aim of this investigation was to tackle the constraints of previous studies and to establish a more comprehensive theoretical framework and practical guidance for safety management. To this end, the phenomenon of workload on mind wandering among drillers during the drilling process was investigated in depth. It focused on drilling site workers, using SART paradigm tasks and EEG devices to track cognitive states under various loads, exploring how they affect mind wandering and EEG mechanisms. Fifty workers participated, observing drilling images to judge accidents. Results showed workload influenced cognitive processes such as mind wandering occurrence, reaction time, accuracy, and brain connectivity. High workload increased reaction time, decreased accuracy, raised mind wandering frequency, altered theta, beta, and gamma waves, and reduced cerebral synchronisation and engagement. Workload affected employees' mind wandering, sensations, focus, and work status, with a positive correlation between workload and mind wandering, potentially harming work performance and safety. Analyzing EEG data helps identify mind wandering and develop intervention measures. In depth research on these features not only helps identify employee mind wandering, but also promotes the development of more precise and personalized intervention measures.
注意力不集中会导致工人忽视安全隐患，延迟做出准确的操作决策，最终增加事故发生的可能性。然而，关于钻井工人注意力不集中时的生理特征的研究相对较少。本调查的目的是解决以往研究的局限性，并为安全管理建立更全面的理论框架和实践指导。为此，深入研究了钻井过程中钻井工人注意力不集中时的工作量现象。它以钻井现场工人为重点，使用连续性能测试范式任务和脑电图设备来跟踪各种负荷下的认知状态，探索它们如何影响注意力不集中和脑电图机制。五十名工人参与其中，观察钻井图像以判断事故。结果表明，工作量影响了诸如注意力不集中的发生、反应时间、准确性和大脑连通性等认知过程。高工作量增加了反应时间，降低了准确性，提高了注意力不集中的频率，改变了θ波、β波和γ波，并降低了大脑同步性和参与度。工作量影响员工的注意力不集中、感觉、注意力和工作状态，工作量与注意力不集中之间存在正相关，可能会损害工作绩效和安全。分析脑电图数据有助于识别注意力不集中并制定干预措施。对这些特征进行深入研究不仅有助于识别员工的注意力不集中，还能促进更精确和个性化干预措施的发展。
