TO THE QUESTION OF CONSIDERATION TECHNOLOGICAL RISK IN PLANNING EXCAVATOR-TRUCK SET OUTPUT

Abstract

The results of efficient planning in the JSC "Uralasbest." open pit are cited. The principle of planning based on consideration technological risk in
the work process faikure of excavator-truck set
(ETS) is proposed. The systematization of mining
factors conditioning the probabilistic nature of ETS
output is performed. According to the results of
mathematical modeling the ETS shift work the dependences of shift task fail risk against the excavator’s workplace quality are received. The calculation of the risk level for the BelAZ-7555 truck in
terms of stop-watch study data from the JSC "Uralasbest" is carried out. The conclusion was drawn
that the risk consideration in the process of calculating the ETS scheduled output in the conditions of
the JSC "Uralasbest" open pits will improve both the
truth of the planning process results and efficiency
of material and technological resources management
