Basis of application of technological scheme implemented in reversing mechanized longwall

Abstract

Currently Vinacomin is actively directing the units in the group accelerate mechanization of coal winning in the face, in special find mining technology solutions for it in complex geological conditions. However, when applying the mechanization technology diagram in the face, it must mention the waste of time and labor costs for the installation and uninstallation of complex equipment. The paper presents experiences of technological scheme implemented in reversing mechanized longwall at underground mines in countries that have developed mining industry and how to determine the tecnology parameters when performing this diagram, it is concurrently research establishments in the future for underground mines in Quang Ninh.
