Разработка стандартизированного подхода по выбору пневматических шин на самоходные машины для подземных горных работ

Abstract

Orientation towards foreign suppliers with their methods and recommendations for tire application on mining machines without taking into account the requirements and specific features of operating conditions in the Russian Federation has led to a lack of domestic regulatory approaches to their use. The article justifies the relevance of developing a standardized approach to selection of giant tires. The development was initiated by “ERT-GROUPP” LLC. Standardization tools are presented, through which the basis for ensuring the quality and efficiency of mine machinery operation will be determined. Provisions of the standardized approach to selection of giant tires for mining machines are developed. An example of tire selection for the Epiroc ST1030 LHD operated in conditions of the Sheregeshskaya mine, EVRAZ ZSMK JSC, is given according to the developed approach to tire selection. The main directions in the industry for application of the standard for the selection of pneumatic tires for underground self-propelled mining machines are given. In conclusion, it is noted that the development of a draft standard for selection of giant tires for mining machines corresponds to the key directions in development of standardization and technical policy to provide the mining industry with modern standardization tools. The use of the national standard entitled “Mining equipment. Self-propelled machines for underground mine workings. The order of selection of pneumatic tires” will contribute to reducing downtime of mining machines associated with the incorrect selection of giant tires depending on the type of machine and the operating conditions, which will reduce economic and material losses of underground mining enterprises.
