摘要：Discrete-and-stochastic simulation model has been developed. The model displays in time and space the interaction between elements of excavating machines complex and deep mining seams complex. Program realization of the model has been created in GPSS Studio simulating modeling tool. The influence of offers for minimization of unplanned downtime of mining machines on daily volume of mined coal by opened- and-underground method has been researched in simulation experiments.
