Research on rock damage under different states of confined water of the bending zone

摘要：

　　The problems of mining under confined water will appear in coal mine production.The rock damage of bending zone with confined water is easily overlooked by people.The physical model of mining under confined water of bending zone is established in this paper.The mechanical effect of floor rock from different states of confined water is discussed and rock damage under confined water in the process of long geological history is analyzed.The development and balance mechanism of the expansion of the microfissure in rock is discussed.Solutions and measures are put forward for possible microfissure extension to fractured zone.
