Abstract

Complex mining and geological conditions of coal exploitation, such as the Soko mine, requiring the
constant work on the research of new technical solutions of development and supporting of the
underground openings.
In this paper presented detailed description of the existing way of development and support
underground openings at the mine Soko.
Experience in the current method of development and supporting of the openings showed a number of
disadvantages especially in terms of increased underground pressures that have affected the
deformation of underground openings.
Installing AT roof bolting system of support and test support in the drift EH- (-60) z in the underground
mine Soko with the combined support represent the new solutions of development and support and
function of the increasing stability of mining facilities, extending the life of their exploitation and
functionality.
