现场观测及实验室试验结果表明采动岩体碎胀量与深厚比成正比，据此得出了初次采动时地表及岩体内部下沉系数计算式．同时，根据受初次采动影响的岩体在重复采动时碎胀量减小，假定减小量与初次采动碎胀量成正比，推出了预测重复采动条件下地表及岩体内部下沉系数的计算式，并可由现场实测得出有关参数，经与３６个初采观测站资料和１０个重采观测站资料的实测资料对比，证明了所给公式的正确性．
The results of field observation and laboratory tests show that the amount of crushing capacity of the mining rock mass is proportional to the ratio of deepness and depth, and the formulas for calculating the settlement coefficient of the surface and rock mass during the initial mining are obtained. At the same time, according to the influence of initial mining, the amount of disintegration of the rock mass which is affected by the initial mining is reduced when the mining is repeated. Assuming that the reduction amount is proportional to the amount of initial dismantling, the surface and rock mass under the predicted reinvestment condition Shen coefficient calculation formula, and can be obtained by field measurement of the relevant parameters, with the 36 primary acquisition stations and 10 re-observation station observation data comparison of measured data to prove the correctness of the given formula.
