The Quantitative Evaluation of Coal Seam Stability Based on Component GIS

Article Preview

Abstract:

The stability of the mining is important for coal, and stability of the current status of coal was analyzed, selecting appropriate indicators that evaluate the importance of stability of the coal seam is so significant. Using GIS Spatial database to achieve a unified data management for spatial data and attributes, and analyze of coefficient of variation of coal thickness and correlation dimension of coal thickness, and use of these two indicators of a coal mine in the coal seam to analyze stability evaluation. Finally, developed stability assessment system of coal based on component-based GIS MapX. The results show that quantitative evaluation of the stability of the coal is reliable, can provide a theoretical basis for coal mining.
