BASES FOR INVESTIGATION OF THE CHANGE OF EXPENDITURE FOR MAINTENANCE OF ROADS BY THE METHODS OF STATISTICAL MODELING

(SGEM Scientific GeoConference, 2004, G. Trapov, I. Markov, A. Smilyanov, D. Hristanov, V. Balikov)

Show more

Expenses for maintenance of mine roads at any moment depend on volumes of road surface, needed for laying at the same moment, to transform roads into a usable condition. A method is presented for their quantitative determination toward a series of consecutive moments and principles of statistical modeling are applied for determining the regularities of change of expenses with the time.

GOAL FUNCTIONS, COMPILED BY HYPERBOLIC FUNCTIONS, FOR OPTIMIZING THE EXPENSES FOR MAINTENANCE AND REPAIR OF MINE AUTOMOBILE ROADS

(SGEM Scientific GeoConference, 2004, I. Markov, A. Smilyanov, G. Trapov, D. Hristanov)

Show more

An option is discussed for creating goal functions for optimizing the expenses for maintenance and repair of mine roads by the means of hyperbolic functions. A transition is presented of the selected hyperbolic functions to a function of decimal liner character and the goal functions are solved parametrically for main betweenrepair schemes.

MINIMIZING THE AVERAGE ANNUAL EXPENSES FOR REPAIR AND MAINTENANCE OF MINE ROADS BY THE USE OF BETWEEN-REPAIR SCHEMES

(SGEM Scientific GeoConference, 2004, I. Markov, A. Smilyanov, D. Hristanov, V. Balikov)

Show more

Expenditure for repair and maintenance of mine auto-roads in opencast mining is neither planned nor managed. There are opportunities for significant reduction of those expenses in case regularities of change of expenses for current maintenance of are known and adequate between-repair schemes are applied.

OPTIMIZING THE AVERAGE ANNUAL EXPENDITURE FOR REPAIR AND MAINTENANCE THROUGH BETWEEN-REPAIR SCHEMES, BASED ON POLYNOMIAL FUNCTIONS

(SGEM Scientific GeoConference, 2004, I. Markov, A. Smilyanov, G. Trapov, D. Hristanov)

Show more

Goal functions – economic-mathematical models for minimizing the average annual expenditure for repair and maintenance of mine roads are composed and solved. The models are composed of polynomial functions. Results are presented from the practice of mines “Vitren” EAD and “Opencast mining” – Pernik, EAD.
