Abstract:
To address the bottleneck problem in the intelligent construction of coal mines caused by the lagging development of the trackless transportation standard system, which restricts the safe and reliable application of new technologies, this study adopts a system intrinsic safety perspective and comprehensively employs methods including literature analysis, vertical standard comparison, case studies, and technical framework construction to systematically review the development history and existing problems of trackless transportation technical standards. Two representative key standards in the field of mine-used flameproof diesel engine trackless rubber-tyred vehicles, MT/T 989–2006 “
The general technical condition of the flameproof diesel vehicle with the rubber wheels for the mine” and MT/T 1199–2023 “
General safety technical condition of the explosion-proof diesel trackless rubber wheel transport vehicles for coal mines”, are selected for detailed technical clause-by-clause comparison and feature analysis. The changes in technical indicators and the transformation of technical concepts are analyzed, revealing the pattern and driving mechanism of the standard system evolving from single-equipment safety to systematic intrinsic safety covering “human-machine-environment-management”. For the emerging mine-used new energy flameproof trackless transport vehicles, considering their power source characteristics and complex underground working conditions, systematic deficiencies and lags in current standards are found regarding key technologies such as battery thermal runaway protection, functional safety architecture, and hybrid powertrain control. Based on the above analysis, an integrated construction path for an intelligent standard system covering system-level design, active safety prevention and control, and data-driven iteration mechanisms is further proposed. Specifically, it includes establishing a dynamic standard revision model based on closed-loop underground operation data and digital twin virtual validation, promoting the transformation of standards from passive compliance-oriented “post-hoc conformity judgment” to proactive leading “pre-adaptive design”, thereby providing standard support for realizing safe, efficient, green, and autonomously controllable intelligent trackless transportation systems.
