APPLICATION OF FLAC TO PREDICT GROUND SURFACE DISPLACEMENTS DUE TO COAL EXTRACTIONAND ITS COMPARATIVE ANALYSIS

Xie Heping1Zhou Hongwei1Wang Jinan1Li Longzhong2M.A.Kwasniewski3 (1 Institute of Rock Mechanics and Fractals, China University of Mining and Technology,Beijing100083China) (2 Hebi Coal Mining Bureau,Hebi456600China)(3 Silesian Technical University,P  
FLAC2D3.3 and FLAC3D1.0 are used to predict surface mining displacement of No.4 Coal Mine of Hebi Coal Mining Bureau, Henan Province. By comparing the results of classical method(probability integral method)with the results of FLAC, it is shown that FLAC, which can simulate the actual geological conditions and improve insufficiency of the classical method, is a simple and effective way.
