摘要
新街台格庙矿区周边均为典型冲击地压矿井,按照工程类比的原则基本上可以确定,未来冲击地压会对本矿区的安全高效开采产生显著的影响。得益于本矿区正处于建设窗口期,可以基于“数字岩石力学+源头防控”的理念,构建出“面向源头、兼容差异、自主适应”的冲击地压数字化源头防控体系,以此最大限度地为安全、绿色、高效生产提供保障。对比周边矿井现状,分析台格庙矿区潜在冲击主控因素,基于数字岩石力学建立台格庙矿区冲击地压数字化源头防控体系架构。通过矿井原生全要素的数字化,构建新街台格庙矿区“物理级透明”的模型,为矿井智能化建设提供更为全面的数据底座;借助能够还原真实工程行为的数字岩石力学推演技术,完成对采掘布局、防控体系等多场景技术方案的超前优选;依托“数据+知识”驱动的方法,实现冲击危险的源头识别及预测,并依据“优化布局无源头,防控到位灭源头,措施精准控源头,超前预见避源头”的原则,构建起能够自主生成具有数据和理论支撑的差异化防控决策生成模块;未来通过在新街台格庙矿区的应用示范,将从源头实现冲击地压矿井全生命周期的差异化防控,为冲击地压煤层的智能安全高效开采以及产能的科学释放,给出“新街方案”。
Surrounding mines of the Xinjie Taigemiao Mining Area are all typical rock burst-prone collieries.Based on the principle of engineering analogy,it can be conclusively determined that future rock burst events will significantly jeopardize the safe and efficient mining operations within this area.Benefiting from the current critical construction period,a digital rock mechanics-enabled source governance system is proposed,characterized by source-oriented design,differentiation compatibility,and self-adaptive capabilities.This system will maximize safeguarding of safe,green,and high-efficiency production.Analyzing dominant controlling factors of potential rock burst in taigemiao mining area through comparative study of adjacent mines,and establishing a digital source governance system framework based on digital rock mechanics.Through comprehensive digitalization of native mine elements,a physically-transparent geological model will be constructed,providing a robust data foundation for intelligent mine development.Leveraging digital rock mechanics simulation technology that replicates authentic engineering behaviors,we will achieve proactive optimization of technical solutions for multiple scenarios including mining layouts and prevention systems.Driven by a“data-knowledge dual-engine”methodology,the system enables:source identification and prediction of rock burst hazards,autonomous generation of differentiated prevention decisions,guided by the principle:“optimized layout eliminates sources,rigorous control extinguishes sources,precision measures contain sources,proactive foresight avoids sources”.Validated through demonstration at Xinjie Taigemiao,this approach achieves differentiated lifecycle rock burst governance from the source.It delivers the“Xinjie Solution”for intelligent,safe,and efficient mining of rock burst-prone coal seams while enabling scientific production capacity release.
