基于智能矿山综合管控平台的放顶煤火灾综合防控策略

    Comprehensive prevention and control strategy for top coal fire based on the intelligent mine comprehensive management and control platform

    • 摘要: 放顶煤开采采空区遗煤多、漏风量大,因此具有较大的自然发火危险性;并且放顶煤产生的粉尘量大、裂隙通道多导致瓦斯涌出量大,一旦发生煤自燃极容易导致瓦斯、粉尘爆炸等次生灾害从而形成灾害链,危害井下工人生命安全。为加强放顶煤采空区自燃防控的效率和效果,提出了基于智能矿山综合管控平台的放顶煤火灾综合防控策略。首先分析了放顶煤开采的火灾特点及危险性,包括采空区遗煤自燃分布、顶板裂隙漏风问题,以及工作面走向长度和推进速度对火灾风险的影响;评估了现有的火灾感知与防控技术及装备,并指出其存在的问题,如感知覆盖范围不完全、预警模型算法不成熟等,基于这些问题,结合智能矿山综合管控平台优势,构建了火灾综合防控中心,并提出了综合防控策略,包括火灾预测预警、煤自燃预防与治理策略,以及关联灾害防控和应急响应救援策略预演。通过智能矿山综合管控平台建设火灾综合防控中心,能够更有效地监测采空区火情,提高智能分析和预警的准确性,同时增强协同防控的可靠性。智能矿山综合管控平台能够实现对放顶煤开采过程中火灾风险的全面、动态和智能化管理。

       

      Abstract: To improve the intelligence and efficiency of mine fire prevention and control, a comprehensive prevention and control strategy for caving coal mining fires based on the intelligent mine integrated management and control platform is proposed. Firstly, the fire characteristics and dangers of caving coal mining are analyzed, including the spontaneous combustion conditions of residual coal in the goaf, the problem of air leakage through roof fissures, and the impact of face length and advancing speed on fire risk. The existing fire perception and prevention technology and equipment are evaluated, and their problems are pointed out, such as incomplete perception coverage and immature early warning model algorithms. Based on these issues, a comprehensive fire prevention and control center is constructed, and a comprehensive prevention and control strategy is proposed, including fire prediction and early warning, coal spontaneous combustion prevention and treatment strategies, as well as associated disaster prevention and control, and emergency response and rescue strategy previews. Through the construction of a fire comprehensive prevention and control center on the intelligent mine integrated management and control platform, the fire situation in the goaf can be more effectively monitored, the accuracy of intelligent analysis and early warning can be improved, and the reliability of collaborative prevention and control can be enhanced. The intelligent mine comprehensive management and control platform can achieve comprehensive, dynamic, and intelligent management of fire risks during the caving coal mining process.
