Research on Situational Awareness of Dual-Operator Collaborative Operation in Intelligent Coal Mine Fully Mechanized Mining Control System

This study aims to explore the situation awareness construction of individuals in different collaborative conditions during dual-person collaborative work in the intelligent coal mine comprehensive mining control system. The study aims to provide relevant basis for the management of personnel collaborative operation modes in intelligent coal mines. The E-prime software is used to simulate the task of monitoring the operating status of the shearer in the intelligent coal mine comprehensive mining control system. Simulated experiments are conducted under different collaborative conditions, including individual work, operational collaboration, work content communication collaboration, and non-work content communication collaboration. The SAGAT is used to measure the individual’s situation awareness scores. The total situation awareness score, scores at each stage of the three-stage situation awareness, and work performance are analyzed to verify the differences in situation awareness impact on individuals in different collaborative conditions. The collaborative modes of dual-person operational collaboration and work content communication collaboration significantly enhance the level of situation awareness and achieve high work performance. In the perception stage of situation awareness, the non-work content communication collaboration group shows a significant decrease in situation awareness scores compared to the other three groups. In the comprehension stage, the work content communication group shows significant differences in situation awareness scores compared to the other three groups, with the highest scores. In the prediction stage, the individual work group shows significant differences in SA scores compared to the operational collaboration group and work content communication collaboration group, with significantly lower scores in the prediction stage than the collaborative groups.
