摘要: 针对黄金矿山闭坑前“二步法”回收竖井保护矿柱问题,探讨了小方块矿层开采尺寸计算,基于采动覆岩非线性传播与克诺特影响函数法,预计了保护矿柱开采引起的竖井下沉与变形,为竖井的维修加固提供了依据,同时为深部开采竖井保护矿柱留设及周边矿体开采对竖井的影响预测提供参考方法。

Abstract: For the "two steps" mining shaft protection pillar before closing gold mine,size of mining for small cube seam is discussed.Based on the nonlinear propagation of mining overlying strata and Knothe influence function,the shaft subsidence and deformation caused by the recovery of protection pillar is predicted.It provides a basis for shaft maintenance and reinforcement and also provides a reference method for design of deep mining protection pillar and prediction of mining surrounding orebody influencing on shaft.
