Prediction of surface fissure in high relief areas induced by underground coal mining
摘要
Abstract
To objectively predict the location and width of surface fissures in high relief coal mining subsidence areas, according to the generation mechanism of surface fissures, a slope segment deforma-tion has been predicted based on the vectors’ decomposition and synthesis principles using the equal gradient slope segment in the main section as research object and the subsidence and horizontal move-ment prediction values as main parameters. Taking the critical deformation value in rock and soil me-chanics as the criterion of the beginning of surface fissures, this model is used to determine the location of the slope segment of the surface fissures and the width of surface fissures per unit length induced by mining. The feasibility and effectiveness of the method are tested by a case study of the 1208~1210 double face subsidence area of Jialequan Coal Mine in Shanxi Province, which shows a good fitness between the observed results and the predicted values and distribution pattern of slope segment defor-mation and location of surface fissures.关键词
