ABSTRACT
The selection of the auxiliary mechanisation for the working conditions on the open pits of lignite in Serbia is a very complex and responsible work which begins as far as the phase of proceeding and investment respond building, and the errors and failures made in the choice (both the kind and the technical characteristics and necessary number) of the auxiliary machines happen to be negative to great extent later and often become the limitation limitations factor of production. Namely, on our open pits of lignite there is applied a highly productive mechanisation of continual effect for whose effective work a suitable preparation is necessary, i.e. carrying out a great number of auxiliary operations on planning, cleaning, transport, maintaining etc.
The lack of this mechanisation of the auxiliary work which is carried out badly or inappropriately make the work of the principal mechanisation very difficult, they affect the fall of the time and capacity exploitation of the system on the exploitation, and the safety both of the mechanisation and the people working with it is often threatened. The proposal of the methodology of the choice of the auxiliary mechanisation for the conditions of the open pits of lignite is presents in this work.
