摘要：

In Sukinda valley at Kaliapani, Dist Jajpur, Odisha, high grade chromite ore is blocked in barrier pillars between opencast mines of different mining companies. The blocked ore is friable and weak in nature. A underhand cut and fill (UCF) method using cemented rock fill (CRF) is described in detail in this paper. This addresses the design of the mining method, design, preparation, transport and placement of CRF in stope. An economic analysis shows that this venture is profitable.
