To monitor the change in stress over ribs against the slice,two stress meters GSC1 and GSC2 were installed in two pillars in such a way that they came almost in the centre ofthe rib after splitting and slicing of the pillar (Fig.1).Monitoring was continued for 85 and 68 days with the face advance till the ribs existed.
The maximum measured change in vertical stress over GSC1 was 1.43 MPa after a period of 80 days from the date of installation (Fig.10).Appreciable change in stress was observed during splitting and slicing operation of the pillar.During
judicious extraction of the rib this value started decreasing and ultimately the stress meter was lost into the goaf.Similarly,maximum measured change in stress over GSC2 was 1.30 MPa after a period of 68 days before going into the goaf.
From the observations of stress meters used in different pillars of GDK-5A incline of SCCL,it is clear that low change in vertical stress are being generated over ribs even after slice formation.Maximum change in vertical stress observed on a rib of 2 m thick in GDK-5A incline mine at a depth of 180 m,was 1.32 MPa which is equivalent to only 30% of the in situ vertical stress.From the 3-D numerical modelling study,it was found that required support load density in the slice was always less than the slice junction and goaf edge and even sometimes less than the spilt gallery for moderate cavable roof strata.
Another point to be considered is the obviously small changes in vertical stress in the rib measured during depillaring.It is generally known that the abutment peak stress is 3-5 times the

在应力监测变化对片,在肋骨和两个应力米GSC1 GSC2被安装在两根铜柱,以这样的方式,他们几乎都来在市中心的肋骨和分散军纪分裂后的支柱(图1)。持续监测是85和68天面部推进到肋骨的存在。
变化的最大垂直应力测量是在GSC1为1.43兆帕,经过一段时间的80天内从安装日期(图10)。在应力的重大转变过程中得到的分裂和分散经营的支柱。在
明智的提取肋骨这个值开始减少,最终的应力计流失到的价值。同样,最大应力超过GSC2测量变化是1.30兆帕,经过一段时间的68天才走进采空区。
从应力米的观测GDK-5A用于不同的SCCL倾斜的柱子,但可以肯定的是,低变化正在产生垂直应力超过肋骨甚至在片的形成。在垂直应力最大变化上观察到的一根肋骨的GDK-5A 2米厚的倾斜矿井,深度为180米,是1兆帕,相当于只有30%的原位垂直应力。研究三维数值模拟,发现需要支持的切片负荷密度总会比切片的交界处,采空区的边缘,有时甚至低于泼出的画廊为中度cavable顶板岩层。
另一点要考虑的是很明显的小变化垂直应力在肋时实测depillaring。一般而言,它是桥台是3 - 5倍的峰值应力
