Abstract

Timing of the time parameters of the technological routes of the transport and technological system of the quarry of the metallurgical enterprise was carried out. The statistical characteristics and laws of distribution of the above-mentioned parameters are determined.

In order to identify the correlations between the parameters of transport service indicators of technological routes and to identify the statistical characteristics of these parameters, the timing of the operation of rolling stock on the technological routes of the transport and production system of the quarry of the metallurgical enterprise was carried out.

The study presents the results of timing of two technological routes of the section of the transport and production system of the quarry. Timing was carried out during four working days in two shifts (from 08.00 to 20.00 and from 20.00 to 08.00).

Timing was carried out according to the following values: loading time, unloading time, driving time with a load, driving time without a load, technological and physiological idle time, number of drives.

The study was conducted using the Wialon software package.

Analyzing the obtained results, it is possible to conclude that idle vehicles before loading (unloading) cargo can occur on any shift during a work shift. This is due to the fact that during the time the car is traveling on the route, the value of the time parameters may be such that the conditions of vehicle downtime arise. In this regard, it can be concluded that the occurrence of idling vehicles on technological routes is of a probabilistic nature.

Key words: timing, distribution law, loading time, unloading time, technological downtime, technological routes, rolling stock, carrying capacity
