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.

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。

Correct judgment and prediction of the safety mining depth effects the scope of the surface to be protected and the stability of spaces underground,and also depends whether the ore bodies over stoped-out areas can be mined safely.In this paper,the data and experience from both coal mining and tin mining of YTC in China are used to calculate and predicate the safety mining depth with non-full and non-fullest rockmass displacement,and some views on tackle of special problems on mining...

安全开采深度的判断和预测是否正确,关系到地表构筑物保护范围以及坑下开挖空间的安危,也决定着已采区上部矿体能否安全回采等问题。本文借鉴煤矿资料及云锡有色金属矿山生产资料,利用计算与类比两种方法,探讨了未充分采动与极不充分采动条件下安全开采深度的计算和预计,并对矿山的一些特殊问题的处理方案提出了见解。

While cola mining transfers to deep place, there should be a safety mining depth, under the which the destructive deformation of the surface structures can not occur. Based on the subsidence calculation of a willful point on the surface, combining the surface sloping, curvature and level displacement deformation, and according to the critical deformation value of the concrete and brick structures, a judgment method and calculation formula of safely mining depth of a coal mine are obtained....

煤矿开采向深部转移时,应该存在一个安全开采深度,在该深度以下开采时,地面建筑物不会发生破坏性变形。依据地下开采时地表任意一点地表下沉计算为基础,结合地表倾斜、曲率、水平移动变形,按照砖混结构建筑物的临界变形值,得出了煤矿安全开采深度的判定方法与计算公式,并探讨和分析了安全开采深度的影响因素。
