摘要
针对文家坪磷矿地下开采岩体移动变形问题,给出了用于预测分析地下开采引起地表移动变形的双曲正切函数模型。并采用该模型对文家坪磷矿1277采区地表岩体移动变形进行了具体的计算分析。文中将理论结果与现场观测的结果进行了对比,二者吻合较好。
A theoretical model for predicting ground displacement and deformation due to mining of phosphate body in Wenjiaping by using hyperbolic tangent function was given in this paper. And ground surface displacement and deformation in the 1277 mining area at Wenjiaping mine were analyzed by using this model. We compared the theoretical results with the field measurements and obtained the satisfactory results.
