"Ground of parameters of method of fight from the displacement soils of making with the use of compensative cavities - Abstract"

The problem of stable of the drift is the most actual problem for Bazanova mine.

This way is most suitable for such conditions. It is based on displacement excavation soil to duffer space. Such a way is economically approved.

Laboratory researches gave next results.

There were created such conditions in our laboratory, and we have such results.

Summary

In this work there was offered a new way of protection of mine working. On the laboratory this method was tested on the models, created of the equivalent materials. As a result there were found the optimal parameters of this method.
