新汶矿区岩体力学参数识别与地表变形预计

Identification of Rock Mass Mechanics Parameters And Prediction of Surface Deformation at Xinwen Coal Mine.

根据新汶矿区浅部观测站资料，以岩石力学为基础，采用了弹性力学有限元法反演了地层力学参数，由反演的采动地层力学参数，预计了深部开采地表移动值，获得了深部采矿地表岩移参数的变化规律，并提出了安全开采深度的实用计算方法，建立了岩层与地表移动、变形与岩体力学性质之间的联系问题，为深部安全开采探明了一条新路。

ed on the aclually-observed data in Xinwen mining area,inversion of the aclually-observed mechanical parameters of strata was made on the basis of rock mechanics by using elastic finite element method.The mechanical parameters thus dervied were used to predict the surface displacement due to mining at depth.Through study,the law governing the variation of strata displacement parameters,the practical method for calcuating the safety mining depth and the strata and surface movement and deformation in relation to mechanical property of rock mass have been brought to light,provoding a new approach for safety mining at depth.
