Application of FLAC to Predict Gound Surface Displacements due to Coal Extraction and Its Comparative Analysis
FLAC在煤矿开采沉陷预测中的应用及对比分析

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.
