Investigation of the stability of ore and rock massifs around the high cleaning chambers during the development of steeply falling potash deposits
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.
