考虑断层影响的煤层开采沉陷三维有限元模拟
Three-dimensional finite element simulation of coal mining subsidence with consideration of faults
摘要
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 reinforcing the club building. The study considers the best mining plan and provides an important basis for protecting the club building at the mine in Shandong. In addition, this study provides an important reference for safe, economic development at small and medium mines with similar conditions.关键词
