Surfer在煤层顶板富水性预测方面的应用

Application of Surfer in Prediction of Water Richness of Coal Seam Roof

为提前预测鹰骏三号井田2煤层顶板岩层富水性情况,为顶板探疏放水提供依据,本文以2煤层顶板导水裂隙带范围内岩层富水性指数数据为基础,通过Surfer软件绘制出富水性等值线图。图形显示2煤层顶板东北方向和西南角富水性较强,是采掘活动中探疏放水工作的重点。

In order to predict the water-rich condition of roof rock in 2 coal seam in Yingjun No.3 mine field in advance and to provide the basis for roof water exploration and drainage,based on the data of water-rich index of rock layer in 2 coal seam roof water-conducting fissure zone,the contour map of water-rich is drawn by surfer software.The graph shows that the northeast and southwest corners of the roof of coal seam 2 are rich in water,which is the key point of water exploration and drainage in mining activities.
