| 中文摘要: |
| 贵州黔西北地区煤矿资源丰富，因由于煤矿开采导致城市地下地质结构变化而引发安全问题。城市地下空间是城市未来发展的重要增长极，拟建城市规划区地下空间地质结构的识别及评价工作极为重要。文中提出基于电场理论、采空区氧化还原环境及煤区地质规律，综合电阻率、电流、自然电位等多个电参数对采煤区拟建城市区地质结构快速识别的方法，并对强风化层、老窑采空区、煤矿采空区等地质结构特征进行评价，取得成果与实地踏勘、已有工程一致，可为城区建设场地地质灾害危险性评价和地下空间开发利用提供重要依据。该方法具有无损、高效、绿色、低成本等优势，值得进一步研究推广。 |

| The northwest Guizhou region contains abundant coal resources. However, safety issues caused by changes in urban underground geological structure due to coal mining have also emerged. Urban underground space is an important growth pole for the future development of cities, and the identification and evaluation of geological structures of underground space in planned urban areas are extremely important. The work proposed a method for quickly identifying the geological structures of the planned urban area in a coal mining area based on electric field theory, redox environment in goaf, and geological laws in coal mining areas. Multiple electrical parameters such as resistivity, current, and natural potential were comprehensively considered, and the geological structure characteristics of the strongly weathered layer, old kiln goaf, and coal mine goaf were evaluated. The results are consistent with field surveys and known engineering projects, and are one of the important basis for geological hazard risk assessment and underground space development and utilization in urban construction sites. Research has shown that this method has advantages such as non-destructive, efficient, green, and low-cost, and is worthy of further research and promotion. |
