Abstract: The use of modern mechanized complexes with high speed advancement of production faces has intensified the problem of development and auxiliary drifts lagging behind. The modern development of the coal industry sets the task of creating high-performance development complexes which ensure high-speed development of underground mine workings with rock bolting. The analysis of the experience of mine workings development showed that in order to ensure an increase in the rate of development, it is necessary to increase the level of mechanization of individual operations of the mining cycle and to create the work organization plan with the provision of operations overlapping.
In the article, the authors propose an option of the composition of the development complex for high-speed development of underground mine workings using a powered walking support that provides continuous support for the roof of the mine workings. The study reviews the composition of the main operations of the development cycle for using a powered walking support as part of the development complex. It was noted that the use of a powered walking support made it possible to separate the individual operations of the driving cycle in space, while they are overlapped in time. The article gives the calculation of the advancement cycle of the powered walking support without taking into account interconnected operations. The authors defined further directions of work in terms of developing a combined development cycle using a powered walking support and determining the technological speed of mine workings development.

Key words: powered walking support development complex mechanization of development development cycle advancing cycle rate of development high-speed development mine working preparatory working
