A variety of mining methods, of which fill mining, open-stope mining and In a mine using forced ventilation, the radon concentration is lowered as the . 2, Open-stope mining, Shrinkage mining, Downward forced ventilation is and most of the seventeen uranium–gold mines in South Africa use forced ventilation systems.... Shrinkage stoping may be termed a “classic” mining method, having been perhaps the most popular mining method for most of the past century. It has largely been replaced by mechanized methods but is still used in many small mines around the world. It is applicable to mineral deposits with regular boundaries and steep dip hosted in a competent rock mass. Also, the blasted ore must not be

4/03/2011 · Shrinkage stoping is an overhand mining method that relies on broken ore being left in the stope to be used as the working platform to continue mining upward and to support the walls. However, the residence of the highly fragmented blasted ore in the stope is a potential hazard for radon and progeny accumulation. Furthermore, this method is to a considerable amount labor intensive and …... Chapter 18. 3 SHRINKAGE STOPING J ACK H A P T O N S T A L L 18.3.1 INTRODUCTION Shrinkage stoping is a vertical, overhand mining method whereby most of the broken ore remains in the stope to form a working floor for the miners.

Shrinkage Stoping Methods Rahma Kasna Academia.edu
8/12/2010 · Shrinkage stoping is a method of mining which is flexible for narrow orebodies that do not need any backfill during stoping. Successive horizontal slices of ore, which are most of the time of about 10 feet (3 metres) high, are taken along the length of a stope, in a form which is very similar to the cut-and-fill method.... 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.

• Stope mapping, for entry-based mining methods (e.g. shrinkage stoping), provides a check and control on the predicted position and structure of the vein, and thus tests the methods and assumptions used to predict stope geology and grade (Fig. 2). It permits reaction, should geological conditions dictate a change in stope dip, strike or width. Time-scales of mapping procedures need to be compa
