It's a similar procedure to cut and fill stoping; however, in cut and fill, the broken ore is removed, and a mixture of barren rock and sand is used as fill. Shrinkage stoping is named as such because the …

Support Systems In Cut And Fill Method Of Stoping | PPT

Introduction 2 Cut And Fill Stoping In cut-and-fill mining, the ore is removed in a series of horizontal drifting slices. When each slice is removed, the void is filled (generally with waste material from the mineral-processing plant), and the next slice of ore is mined. Backfilling provides not only a platform for mining of each slice of ore ...

Underground Mining Methods and Equipment

Cut-and-fill and stull stoping are intended for moderately competent rock, whereas square-set stoping is suitable for the least competent rock. Supported methods have declined in use since World War II, primarily because cut-and-fill stoping is the only method that lends itself to mechanization. Stull stoping and square-set stoping are
