摘要：Most and local minable seam in mining field has seven layers, according to the label from top to bottom in turn as follows:13, 12, 10, 9, 8-3, 8 -2, 8-1. coal, total minable seam thickness of 21.92 m, dip angle of coal seam located between 4° and 24°, is nearly horizontal seam. The average thickness is 116.48m. Given the existence of tertiary pore fissure aquifer, in order to predict effectively the impact of the aquifer on site production when seven layers of coal are mined, this paper uses FLAC3D numerical simulation for comparative analysis of the coal mining water fractured zone height, which determine the safe mining boundary thereby provide theoretical guidance for the field working face layout, mining area connection and other safety production.
