Watery of Coal-bearing Sandstone Aquifer Analysis and Forecasting with Multi-factor
Sandstone fracture water of coal seam commonly exists in rock fracture with static reserve. For the water-richness of coal measures sandstone, it is usually classified with specific capacity, because of the heterogeneity of sandstone fracture, this method is proved to be unscientific in mining practice process. By the method of pumping test, the actual observation of water detection and release in the mine, engineering geology test and water properties test, etc. , factors including the thickness of sandstone, percentage of sand-shale, cycle liquid leakage of drilling, geophysical data, complexity of fault structure and mine discharge were choosen to evaluate sandstone water-richness comprehensively. It is effective and scientific compared to traditional method. Based on the structure principle of analytic hierarchy process (APH), fitting the above six factors though multivariate information, the sandstone water-richness of coal seam roof was analyzed quantitatively. It provides the basis for coal seam roof sandstone water prevention.
