| Abstract: | The structure and movement law of coal face overlying strata in certain coal mine are researched based on the theory of key strata and 3DEC numerical simulation.Through the different mining height model,the increase of bed separation and the proceeding of roof caving line are the two characters of movement of overlying strata in fully mechanized mining with great mining height. |
