Due to rheological properties of salt rock mass, maintenance of mine excavations, including shafts may be very challenging, especially in the long term. Many different ideas and approaches to a subject of sinking and maintaining a shaft in salt rock mass have emerged over the years, of which the main directions include two opposite ideas, such as an application of high-strength lining and an approach based on flexible lining. The article presents a shaft reaming machine designed for maintenance of mine shafts located in salt rock mass designed with a flexible shaft lining approach.

A level of mine safety is related directly to the condition of its shafts. Thus regular monitoring and maintenance of shaft lining and equipment is vital. However such works are always hard and dangerous, as they are conducted from conveyances. Working platforms are a significant improvement in case of emergency shaft works. However, they need some extremely precious time for assembly. An idea of pull out working platform combines safety and convenience of typical working platform with short time of its installation. Following work presents the idea and construction of the mobile working platform unit, which is a solution for improvement of shaft works conducted from the compartment of the conveyance, as the platform uses cage for transport and operation.
