Mineworkers' Perceptions of Mobile Proximity Detection Systems.

Area of Science:

• Mining Engineering
• Occupational Safety and Health
• Human Factors Engineering

Background:

• Mobile haulage operations present significant risks of pinning, crushing, and striking incidents in mines.
• Proximity detection systems (PDSs) are designed to mitigate these hazards and enhance mineworker safety.
• Unintended consequences and operational hindrances associated with PDSs can potentially negate their safety benefits.

Purpose of the Study:

• To explore mineworkers' perspectives on the operational effects and safety implications of mobile PDSs.
• To identify challenges and unintended consequences arising from PDS implementation in underground mining.
• To gather user-based recommendations for improving PDS design and integration into mining operations.

Main Methods:

• Qualitative research approach involving semi-structured interviews.
• Data collection from mineworkers across seven mines utilizing mobile PDSs on haulage equipment.
• Thematic analysis of interview transcripts to identify key operational impacts and user concerns.

Main Results:

• Mineworkers reported that PDSs significantly impact various operational tasks including loading, tramming, section setup, and maintenance.
• Identified issues include increased operational burden, heightened worker exposure, and new or altered risks.
• Specific concerns were raised regarding task compatibility, training effectiveness, logistical integration, and system performance.

Conclusions:

• Iterative user input, particularly from mineworkers, is essential for optimizing PDS design and mitigating unintended consequences.
• Addressing operational challenges and enhancing PDS task compatibility, training, and performance can improve safety outcomes.
• Further research into PDS design and implementation strategies informed by end-user perspectives is recommended for effective risk reduction.
