  • 摘要: 巷道掘进是煤炭开采的关键先行工程,其人−机−环系统具有多灾种共生耦合特征,形成突水、瓦斯、顶板坍塌、机械伤害等多灾种共生的特殊风险体系,进而导致安全风险管控难度大。针对煤矿智能化建设需求,构建了基于人−机−环系统耦合的多灾种风险判别模型,提出了基于信息感知与智能决策的灾害主动抑制技术路径,研发了掘进工作面安全风险智能管控与应急平台,实现了掘进工作面风险信息协同监测,解决了复杂工况下掘进设备群协同性差、信息缺乏连通性及智能管控手段不足等问题。该平台以多源异构数据融合(Service-Oriented Architecture架构)和数字孪生技术为基础,集成灾害风险预测预警(基于Transformer时序模型)及人员违章与危险状态智能视频分析(基于YOLOv5+长短时记忆网络模型)等核心技术,实现了突水、瓦斯、顶板、机械伤害等主要风险的三维可视化辨识与动态预警;人−机−环−管多源数据的深度关联分析与闭环管控;通风除尘设备智能联动调控;人员违章行为的AI识别(准确率>85%)。在陕煤集团柠条塔煤矿的应用表明,该平台显著提升了掘进面安全风险管控能力,风险预警准确率达92%以上,有效响应了《关于进一步加强矿山安全生产工作的意见》对灾害链防控的要求,为煤矿智能化建设中的掘进本质安全提供了关键技术支撑。

     

    Abstract: The tunnel excavation is a key and pioneering project in coal mining, and its human-machine-environment system exhibits characteristics of multi-disaster coexistence and coupling. It forms a special risk system featuring the coexistence of multiple disasters such as water inrush, gas, roof collapse, and mechanical injury, making the safety risk management extremely challenging. In response to the demand for intelligent construction in coal mines, a multi-disaster risk discrimination model based on the coupling of human-machine-environment systems has been established. A technical path for proactively suppressing disasters based on information perception and intelligent decision-making has been proposed. An intelligent safety risk control and emergency platform for tunneling faces has also been developed. The collaborative monitoring of risk information for the tunneling workface has been achieved, addressing issues such as poor coordination among the tunneling equipment group under complex conditions, lack of information connectivity, and insufficient intelligent control measures. This platform is based on multi-source heterogeneous data fusion (Service-Oriented Architecture architecture) and digital twin technology, integrates core technologies such as disaster risk prediction and warning (based on Transformer time series model) and intelligent video analysis of personnel violations and dangerous states (based on the “YOLOv5 + Long Short-Term Memory Network” model), and achieves: Three-dimensional visualization identification and dynamic warning of main risks such as water inrush, gas, roof, and mechanical injury; Deep correlation analysis and closed-loop management of multi-source data of human-machine-environment-management; Intelligent linkage regulation of ventilation and dust removal equipment; AI intelligent recognition of personnel violation behaviors (accuracy rate > 85%). The application of this platform in Ningtiaota Coal Mine of Shaanxi Coal Industry Group has demonstrated that it significantly improves the safety risk management capability of the tunneling face, and achieves a risk warning accuracy rate of over 92%, effectively responding to the requirements of the “Opinions on Further Strengthening Mine Safety Work” for disaster chain prevention and control, and providing key technical support for the intrinsic safety of tunneling in intelligent coal mine construction.
