Cut And Fill Stoping

Cut and fill stoping is a method of underground mining used in vertical stopes and in mining high-grade irregular ore bodies. The rock mass surrounding the ore deposit is also usually weak unable to support loads over an extended stoping height.

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 of development.

ABSTRACT Mechanised cut and fill stoping in the Racecourse orebodies between II and 9 levels was started in 1964. Five stopes are in progress over the two level interval, extracting the full strike length (600-2,000 ft) of each orebody without transverse pillars. Each …

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

16-10-2020· Other articles where Overhand cut-and-fill mining is discussed: mining: Cut-and-fill mining: In overhand cut-and-fill mining, the most common variation, mining starts at the lower level and works upward. In underhand cut-and-fill mining, work progresses from the top downward. In this latter case cement must be added to the fill to form a strong roof under which to…

Overhand cut-and-fill. Information. The ramp is developed further than the crosscut stope access elevation. Access to the orepass is excavated. The crosscut access to the ore advances at -20%. The first cut of the stope is excavated by high drifting in the ore.

09-03-2018· Cut-and-Fill Stoping. Cut-and-fill stoping is a preferred method for high grade ore bodies with a steep dip size or irregular shape or vein structure. It is a versatile method that provides high ore recovery and is suitable for deposits that require mining ore out of selected ore pockets.

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 …
