Ways of improvement of the layer caving system with the use of flexible covering
Abstract
Layer caving is in many cases the only acceptable mining system, so the issues of improving its efficiency are of great practical importance for the ore industry. However, this system is characterized by low productivity of the faces and high labor intensity of works, in particular, support of working faces. Therefore, it is very tempting and promising to study the possibility of layer mining with the use of only one flexible covering. In this case, the working space of the face will be between the sagging part of the flexible covering ab and the face wall av. A successful solution of the problem would make it possible to work the layers in a very simple and cheap way and thus significantly increase the efficiency of the layer caving system.
