2019-6-28  Overhand cut and fill evolved from square set stull stoping to provide stronger support. In this method, mining begins at the bottom of the ore body or block and progresses upward. During the mining sequence, the back of the excavation is temporarily supported using rock bolts before the stope is back filled to form the floor of the next level

MN 372 Underground Mining Systems Instructor: Prof. Raymond S. Suglo 1 CUT-AND-FILL STOPING METHOD In cut-and-fill mining the ore is excavated in horizontal slices, starting from the bottom of a stope and advancing upwards. The blasted ore is loaded and completely removed from the stope. When the full slice has been excavated, the corresponding volume is filled with waste material.

2016-9-19  The standard application is that cut-and-fill can be applied to steeply dipping ore bodies with reasonably firm ore. Compared with sublevel stoping and shrinkage, used in similar conditions, cut and fill offers the advantage of almost full selectivity. The method can be applied to irregular ore bodies with any type of discontinuities.

In cut and fill mining the ore is excavated by drilling and blasting in horizontal slices, starting from the bottom of a stope and advancing upwards as in shrinkage stoping. A slice has a thickness of not more than 3m. The broken ore is loaded and completely removed from the stope. When one slice of ore has been excavated, the corresponding volume is filled

2020-8-25  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

2016-7-19  So, the cut and fill process is typically one of the first construction processes to take place on a site. Without computer software to determine the amount of land to be added or removed, we can do simple calculations to estimate the cut and fill volume of any site. First, the site is divided into sections.
