| Abstract: | The coal mining under seabed has great importance and long strategic significance on the development of coal industry in China, which indicates that the coal resources exploitation has entered into a new history period of coal mining under seabed. Through the forecast research and the test of the actual measurement, the paper opens up the movement rule of cover rock when the mining technology of the top coal caving is adopted in the soft coal bed. It establishes the foundation on achieving safe coal mining under seabed with high efficiency. |
