Study on Water Enrichment Prediction of Coal Roof Sandstone Based on GRNN
Sandstone roof water is the direct water-filling resource of coal mining, which has a great effect on the mine production. However, because of the unequal enrichment of Sandstone roof water, it is difficult to prevent and treat sandstone roof water. In order to study the water enrichment of coal roof sandstone, take 8# coal seam of ZhangBei coal mine as an example. Based on the analysis of influencing factors and the establishment of evaluation index system of the enrichment of sandstone roof water, water enrichment of coal roof sandstone was predicted by the use of GRNN. Researches have shown that the influencing factors of water enrichment of roof sandstone include sandstone thickness, mudstone thickness, fracture strength and fracture density. The prediction model of water enrichment of coal roof sandstone based on GRNN has the good ability of prediction and generalization, and the predicted results can provide certain basis for water prevention and treatment of sandstone roof water.
