Abstract The connotation of coal mining science, safety production and efficient mining mechanization and automation, improving coal and associated resources sustainable mining recovery rate, taking into account the environmental tolerance, protecting and restoring the environment were the basic requirement of scientific exploration. Coal mining in our country had a large production, excessive concentration, large regional differences, poor security situation, the environment pressure, urgent need science exploration. With the rapid development of coal mining technology introduced, at the coal mining technology application scope greatly improved. Mining in thick coal seam mining height, special thick coal seam sub-level caving mining, filling mining, machine manufacturing, coal and gas, mining, large dip angle of coal seam mining have made important progress, which supported the implementation of coal mining science.
