Operators of roof bolting machines in underground coal mines do so in confined spaces and in very close proximity to the moving equipment. Errors in the operation of these machines can have serious consequences, and the design of the equipment interface has a critical role in reducing the probability of such errors.
An experiment was conducted to explore coding and directional compatibility on actual roof bolting equipment and to determine the feasibility of a visual feedback system to alert operators of critical movements and to also alert other workers in close proximity to the equipment to the pending movement of the machine. The quantitative results of the study confirmed the potential for both selection errors and direction errors to be made, particularly during training.
Subjective data confirmed a potential benefit of providing visual feedback of the intended operations and movements of the equipment.
This research may influence the design of these and other similar control systems to provide evidence for the use of warning systems to improve operator situational awareness.
地下煤矿的锚杆机操作人员在狭小的空间中，且紧邻移动设备进行操作。这些机器操作中的错误可能会产生严重后果，而设备界面的设计对于降低此类错误的发生概率起着至关重要的作用。
在实际锚杆设备上进行了编码和方向兼容性的实验，以确定可视反馈系统的可行性，以警示操作人员关键动作，并提醒设备附近的其他工人即将发生的机器移动。该研究的定量结果证实，特别是在培训期间，可能会出现选择错误和方向错误。
主观数据证实了提供设备预期操作和运动的视觉反馈的潜在好处。
这项研究可能会影响这些和其他类似控制系统的设计，为使用警告系统来提高操作人员的情境意识提供证据。
