Abstract:

Purpose. Creation of new technological systems to maintain in-seam working in the Western Donbass mines.

Methodology. Frame and roof bolting support which is used in the preliminary workings requires overmaintenance. Development of new types of bolting by means of solid modeling and numerical analysis allows making development workings maintaining easier and safer.

Findings. Designed lining simplifies mount and unmount of bearing structures used for protection of development workings in mines of the Western Donbass.

Originality. A comprehensive approach to ensuring development working stability through application of universal bearing structures concordant with the main technological processes in the mine was applied.

Practical value. Mounting and maintenance of ordinary kinds of support require work of high-skilled tunnellers’ brigade. Use of new designed kind of support can reduce operating costs per linear meter of lining up to 30% and improve coal production in the Western Donbass mines.
