摘　　要：为防治羊场湾煤矿16号煤层底板水害,基于《煤矿防治水规定》中提出的煤矿底板突水系数评价方法,以羊场湾煤矿矿区范围内钻孔数据为基础,依据克里格(Kriging)插值法,提出了优化绘制羊场湾煤矿16号煤层底板突水系数等值线图的新方法。结果表明:新方法通过优化插值钻孔数据,增加了插值钻孔数量,提高了突水系数等值线图的精度。使用新的插值方法没有增加新钻孔,优化绘制出的羊场湾煤矿16号煤层底板突水系数等值线图精确度更高,为羊场湾煤矿底板水害防治提供了技术支持,为今后同类型煤矿底板突水系数等值线图的绘制提供了新思路。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.
