摘要
通过理论分析、现场监测和数值模拟等方法的结合,研究了魏墙煤矿1301首采工作面地表移动变形规律,得出地表移动变形相应的基本参数和概率积分预计参数,为今后矿区在类似地质条件的煤炭开采、保护煤柱的合理留设、环境保护等提供理论技术指导和参考。
Through the theoretical analysis and field monitoring and numerical simulation methods,the combination of Weiqiang 1301 mining face in coal mine is studied surface movement deformation law,it is concluded that surface movement deformation corresponding basic parameters and probability integral are expected,and protect the coal pillars in the mining area in similar geological conditions in the future.The reasonable reservation and environmental protection provide theoretical and technical guidance and reference.
