地球系统科学视角下供给侧驱动的煤炭减损开采地质保障OA

Against the backdrop of sustained growth in China's energy demand and the progressive exhaustion of coal resources in eastern mining districts,coal-bearing regions in Northwest China are assuming an increas-ingly important role in maintaining long-term energy supply stability.Nevertheless,coal extraction in this re-gion is inherently constrained by fragile geological settings,which pose fundamental challenges to large-scale,deep,and long-duration mining activities.As mining disturbances accumulate over time,tensions between coal exploitation and the regional geological-environmental system continue to intensify.In this context,this study focuses on the coupled responses of key Earth system components,including the lithosphere,hydrosphere,eco-sphere and atmosphere,to coal mining disturbances.Drawing on the conceptual framework of Earth system sci-ence,geological safeguard requirements and implementation pathways for loss-reducing coal mining are pro-posed.First,it provides an in-depth analysis of the effects of coal mining on Earth's multi-spheres and clarifies the relationship between Earth system science and coal mining.Second,from the perspectives of Earth system science,such as holism,dynamism,quantification,and systematization,it innovates the geological support re-quirements for low-impact coal mining in terms of geological survey methods,evaluation of geological ele-ments,evolution of geological conditions,and sustainable development of geological resources.Finally,by inte-grating multi-scale and multi-approach exploration and observation technologies,a geological survey method and a three-dimensional dynamic monitoring model covering the entire coal mining lifecycle are established.Utilizing massive,multi-source,and diverse measured data,a multi-sphere coupling model is constructed to quantitatively analyze the dynamic evolution of geological elements during coal mining,thereby building a sup-ply-side-guided guarantee system for minimizing mining-induced damage.From a methodological standpoint,Earth system science offers an effective framework for interpreting the interconnected responses of multiple Earth system components induced by coal mining,while mining activities provide a natural laboratory for ex-ploring multi-sphere coupling mechanisms.Geological safeguard research for loss-reducing coal mining there-fore necessitates a fundamental paradigm shift from traditional practices characterized by static assessments,segmented stages,experience-based judgments,single-sphere isolation,and production-oriented priorities to an integrated approach centered on process-based dynamics,quantitative geological characterization,multi-sphere coupling,and sustainability considerations.To support this transition,a comprehensive geological safeguard sys-tem is proposed,incorporating an integrated"space-air-ground"monitoring network,quantitative models de-scribing cross-sphere interactions,and supply-side driving mechanisms.This system is intended to enable a full life-cycle framework for loss-reducing coal development,extending from precise early warning of mining-in-duced risks to diversified utilization of resources and products after mine closure.This research provides impor-tant theoretical support for achieving green mining of coal resources and holds significant practical value for the implementation of strategic national energy policies in the northwest region.
