IMPROVEMENT OF NON-PURPOSE PROTECTION METHODS OF REUSABLE PREPARATION WORKINGS
Abstract
Preparatory workings provide for the preparation of individual parts of the mine field and the development of extraction pillars. In order to accommodate a significant amount of equipment, ensure uninterrupted operation of transport and allow a large amount of air to pass through, it is necessary that the cross-section of the preparatory workings meet the requirements of the Safety Rules. At the same time, in order to maintain the cross-sectional area, permissible gaps between the walls of the working and transport during operation, it is necessary to use reliable security methods. In the mines of the Kuznetsk Basin, coal pillars are used to protect the extraction workings adjacent to the longwall; as a rule, they are left at the junction of the longwall and the working. Pillarless technology for the preparation and development of extraction pillars accounts for about 30%.
