Abstract

The tendencies existing in the world practice of underground development of steeply falling deposits of potassium salts by chamber system, testify that one of the most perspective directions of creation of technology of future mining enterprises is reduction of irretrievable losses of a mineral in the subsoil at the expense of increase of chamber stocks of a block by change of its sizes, including increase of height of a storey, in a combination with filling of worked-out space.
