It is critical for the safety of miners to be able to escape, unaided, during a mine emergency. Self-escape is challenging in the presence of smoke that can occur during a mine emergency. To assist self-escape, coloured markers in underground mines designate the primary/secondary escapeways, but no universal colour code exists. Ten participants were tested to recognize the colour and designation (primary/secondary) of fluorescent yellow–green (FYG), yellow (Y), white (W) and green (G) escapeway markers in both a clear and smoked-filled environment. The overall misidentification rate for all colours was 1.9% and 18.1%, respectively, in clear and smoke conditions. FYG had the highest misidentification percentage for both conditions. For the marker designation tests, participants were most accurate in clear conditions (100.0%) for the FYG + W, Y + G, G + W and W + FYG combinations, and least accurate (89.6%) for the Y + FYG combination, while for smoke conditions participants were most accurate for the G + Y combination (95.8%). The overall effect of colour combination was significant, indicating that the colour combination for primary/secondary recognition is a significant factor where the G + Y combination was best. It can be inferred from these data that the colour combination is an important factor in participants’ ability to recognize primary/secondary escapeway markers in smoke conditions.

识别指示主要和次要排雷通道的发光彩色标记

在矿山紧急情况下，能够在无人帮助的情况下逃生对于矿工的安全至关重要。在矿山紧急情况期间可能出现烟雾的情况下，自我逃生具有挑战性。为了帮助自我逃生，地下矿井中的彩色标记指示主要/次要逃生通道，但不存在通用颜色代码。测试了 10 名参与者在清晰和充满烟熏的环境中识别荧光黄绿色 (FYG)、黄色 (Y)、白色 (W) 和绿色 (G) 逃生通道标记的颜色和名称（主要/次要）。在晴朗和烟雾条件下，所有颜色的总体错误识别率分别为 1.9% 和 18.1%。FYG 在这两种情况下的错误识别率都最高。对于标记指定测试，参与者在晴朗条件下 (100.0%) 对于 FYG + W、Y + G、G + W 和 W + FYG 组合，Y + FYG 组合的准确度最低 (89.6%)，而对于烟雾条件，参与者对 G + Y 组合的准确度最高 (95.8%)。颜色组合的整体效果显着，说明一次/二次识别的颜色组合是G+Y组合最佳的重要因素。从这些数据可以推断，颜色组合是参与者在烟雾条件下识别主要/次要逃生通道标记能力的重要因素。表明主要/次要识别的颜色组合是 G + Y 组合最佳的重要因素。从这些数据可以推断，颜色组合是参与者在烟雾条件下识别主要/次要逃生通道标记能力的重要因素。表明主要/次要识别的颜色组合是 G + Y 组合最佳的重要因素。从这些数据可以推断，颜色组合是参与者在烟雾条件下识别主要/次要逃生通道标记能力的重要因素。
