SIMULATION MODEL FOR PLANNING MINING OPERATIONS

The importance of potassium fertilizers produced by Uralkali, Berezniki, Perm Region to agriculture and economy as a whole is illustrated. The process of potassium ore mining is described. The information on planning of operation of mining machines is given. The problem of production schedule adjustment is presented. The problem can be solved by simulation modeling. The popular software for simulation modeling of mining operations features some shortcomings in terms of potassium mines. For this reason, a special object-oriented library is used, which allows modeling mass service, multi-agent and active systems. It is assumed to model mining operations by deterministic automation up to ore transfer to conveying and haulage subsystem. The special states of the model, such as mining machine, self-propelling car and its unloading point, are described. The model is fed by the data from open publishers. The model relevance is tested, and its responses to changes in parameters are examined. It is shown that downtime of mining machines grows in a pulsating mode due to passages between stopes; at the same time, owing to mandatory operations unconnected with ore cutting, this pulsating is insignificant. It is shown that in transition to a stochastic model, the output of a cutter–loader decreases as expected. As a result, the model applicable to adjustment of work schedule in a potassium mine is constructed.
