Service maintenance of pneumatic tyres for mobile underground mining machines

Abstract

The article presents the issue of short life of pneumatic tyres for mobile underground mining machines. It is noted that the correct choice of pneumatic tyres will increase the tyre life, but for a greater increase it is necessary to control the entire life cycle of the tyre, i.e. to carry out its service. The life cycle stages to be taken into account during tyre maintenance are presented. Control at each stage will minimise damage to the pneumatic tyres. The maintenance phase should include the records of tyre usage history and stock management. Analysis of the records will help to determine the reasons for tyre rejection and the wear conditions, the tyre condition before and after repair, and before and after retreading. Service maintenance of pneumatic tyres will allow planning the approximate level of stock, replacement periods and effective stock management. The article justifies the relevance of holding joint meetings of service specialists, tyre designers, and the company’s. In conclusion, it is noted that the issue of creating a national standard of service maintenance of pneumatic tyres for mobile underground mining machines is relevant.
