大采高工作面采高合理性研究及煤壁片帮防治
Research on the reasonable mining height and the coal wall spalling prevention of working face with large mining high
摘要
Abstract
Through the analysis of numerical simulation obtains the reasonable mining height is 6.5m great mining height in fully mechanized working face of coal mine S8310;through the analysis of the coal wall spalling reason, put forward the control method to prevent the coal wall spalling, which lay the foundation safety technology to enhance the stability of large mining height working face, and reduce the coal wall spalling.关键词
