Abstract
The probing method of breakage depth mined are Introduced, and the geology, hydrology and rock strata structure of the coal seam floor mined in the test work face are analyzed. the worth of the breakage depth mined of the 6 coal seam floor in the No.2 coal mine of Liu qiao and Zhu zhuang coal mine are acquired. The results show that the probing method of floor breakage depth is different, but its regularity is similar, and the floor breakage depth is clearly controlled by floor rock strata structure.
