| Abstract: | In order to have a fully mechanized top coal caving mining applied to high inclined thick seam in a mine with a depth over 1 000 m, the paper studied the technical parameters, roof and top migration law and mine pressure law affected to the fully mechanized top coal caving mining in high inclined seam of a mine with a depth over 1 000 m with a similar material simulation, numerical simulation, site test and others. After the test, an optimized coal caving mining method with two mining operations and one coal caving operation, multi time spaces and from top to low mining operation were obtained. The technical parameters and mine strata pressure behavior law of the fully mechanized too coal caving mining in high inclined thick seam were fully understood with a safetv coal mining operation. |
