摘要
Abstract
There are many researches on mining technology of lower protective layer in China. Some achievements have been made in the field of pressure relief principle, stress field distribution and rock burst prevention and control. But under the actual conditions, when the upper protective layer is used, the stress field distribution and stress concentration of the upper protective layer are different from those of the lower protective layer. Therefore, it is of great significance to explore the causes of rock burst in the upper protective layer.关键词
