Abstract

The structure of the rig includes many complex mechanisms -their wear, and the value of the residual life depending on it, directly depend on the operating conditions of the rig. In compliance with all the norms and technical conditions of drilling and the absence of abnormal situations in its process, all components must develop their resource, defined by technical conditions, after which they need to be replaced. When various types of complications and abnormal situations occur in the drilling process, the load on the drilling machinery mechanisms can increase dramatically, which does not necessarily lead to the drill failure, but it affects the residual life of those mechanisms and components, the loads that exceed the standard values. With subsequent occurrences of similar situations in the drilling process, this may lead to failure of the drill. The article presents the rationale for choosing a simulation model for organizing a system for supplying drilling rigs with spare parts and accessories based on the theory of queuing systems. The work is an integral part of previously published developments presented in the materials of articles in 2-nd and 3-rd International innovative mining symposiums (2017-2018).
