  • In order to prevent and control the water damage to the floor of the No.16 seam in Yangchangwan Coal Mine,the evaluation method for the coal floor water inrush coefficient proposed in the Coal Mine Prevention and Control Water Regulations is based on drilling data in the Yangchangwan coal mine area,based on Kriging Interpolation,a new method to optimize the drawing of the contour map of the floor water inrush coefficient of No.16 coal seam in Yangchangwan Coal Mine was proposed.The new method increases the number of interpolated boreholes by optimizing interpolation drilling data,and improves the accuracy of the water inrush contour map.The results show that the new interpolation method does not increase the number of new boreholes,and the accuracy of the isoline chart of the floor water inrush coefficient of the No.16 seam in the Yangchangwan Coal Mine is higher.This provides technical support for the prevention of floor water damage in the Yangchangwan Coal Mine.This will provide new ideas for the drawing of contour maps of the same type of coal mine floor water inrush in the future.
