| 摘 要： | 为了解决山东某煤矿的煤层开采对周边俱乐部沉降的影响问题,采用有限元分析的方法并建立不同开采方案的三维地质模型,同时考虑断层的影响,计算出煤层开采后俱乐部四角的地表下沉状况。研究结果表明:回采3101工作面时俱乐部地表下沉最大值达到382 mm,因此建议对俱乐部进行加固保护处理。该成果为研究最佳开采方案及周边俱乐部的保护提供重要依据,同时为浅埋煤层以及类似条件下中小矿山合理、安全、经济的开发提供了重要的参考依据。

| Abstract: | To solve the surface subsidence problem surrounding a club building at a coal mine in Shandong,various three-dimensional geological models have been developed for different mining plans using finite element analysis method in this study.The models take into account faults impact and are used for estimating the surface subsidence at the four corners of club building after coal mining.The results show that the largest subsidence is 382mm caused by extracting Face 3101.A recommendation is provided for reinforc... |
