摘要
煤矿开采对我国能源供应至关重要,但随之产生的地质灾害问题日益严重,已成为矿山环境治理的重要关注点。纳林河二号矿井31116工作面区域因地下采空区引发的地质灾害对矿井安全生产构成了重大威胁。为深入探讨这些地质现象的成因及其影响,本研究采用三维高密度电阻率法结合现场勘查,对该区域2020年发生的地表裂缝与塌陷坑进行了系统分析。研究表明,塌陷坑与裂缝的形成主要受地下风积砂层厚度及水文地质条件的影响。电阻率反演结果与钻探揭露的地层情况高度吻合,进一步证实了地下水位波动对地表沉降的显著影响。本研究为该区域及类似区域的矿井的安全生产提供了重要的科学依据。
Coal mining is crucial for China's energy supply,but the resulting geological hazards are becoming increasingly serious and have become an important focus of environmental governance in mines.The geological disasters caused by underground goaf in the 31116 working face area of Nalinhe No.2 Mine pose a significant threat to the safety production of the mine.In order to further explore the causes and impacts of these geological phenomena,this study used the three-dimensional high-density resistivity method combined with on-site investigation to systematically analyze the surface cracks and subsidence pits that occurred in the region in 2020.Research has shown that the formation of collapse pits and cracks is mainly influenced by the thickness of underground aeolian sand layers and hydrogeological conditions.The resistivity inversion results are highly consistent with the geological conditions revealed by drilling,further confirming the significant impact of groundwater level fluctuations on surface subsidence.This study provides important scientific basis for the safe production of mines in this region and similar areas.
