徐州旗山矿采空区地面塌陷特征及治理方案优化
Characteristics of Goaf Ground Collapse and the Optimization of Its Treatment Scheme in Qishan Mine, Xuzhou, China

采煤塌陷区的治理是一项多学科、多技术手段的综合治理，废弃矿区的地面塌陷区治理对于生态修复具有重要意义。分析了研究区采空区地面塌陷的特征，根据塌陷程度划分为严重区、较严重区和轻微区，阐明了研究区的采空区地面塌陷防治方法，针对研究区的塌陷区治理设计了A、B两套方案，通过技术、经济的综合对比，认为方案B具有更优的经济技术合理性，有利于提高研究区地面塌陷治理的综合经济效益，也具有较好的参考价值。
The treatment of coal mining collapse area is a comprehensive treatment of multi-disciplinary and multi-technical means, and the treatment of ground collapse area in abandoned mining area is of great significance to ecological restoration. In this paper, the characteristics of goaf ground collapse was analyzed, taking the Xuzhou Qishan Mine as an example, the goaf ground collapse was divided into serious, relatively serious and slight areas according to the degree of collapse. The prevention and control methods for the goaf ground collapse were clarified, and two sets of schemes A and B for the treatment of collapse area in the study area was designed. Through the comprehensive comparison of technology and economy, scheme B is considered to have better economic and technical rationality, which is conducive to improving the comprehensive economic benefits of ground collapse treatment in the study area and also has better reference value.
