Caving Methods of Mining. There are three distinctive methods of working large deposits that involve, in some way, the factor of caving. Slightly different names are in use, but those that are simple as well as descriptive are top slicing, sublevel caving, and block caving.

Cave Mining Techniques Mining Information

Block Cave Mining Techniques. The most commonly used cave mining technique is block caving. Block caving is a large-scale mining method that is particularly useful for mining low-grade or disseminated ore bodies which are at too great a depth to be exploited through open-cast mining. This mining technique gets its name from the layout of the .

Caving Mining Method Gocomchinam

During the production process, the ores fall as the covering layer is caved and the fallen rocks fill the goaf, which enable the continuous stoping. The method is favored for low cost, high efficiency and large scale. At present, there are mainly sub-column sublevel caving method, sub-column sub-leveling method and natural caving method.

Sublevel Caving. In this method, the stope is divided into sublevels, fairly close to each other, normally with 8-15m vertical interval between each two adjacent ones. These sublevels are called sublevel drifts or production drifts. Production is carried out from the sublevel drifts by means of long holes above the end of the production drifts.
