The article proposed equation criteria specifying the interaction force field with the medium.Based on the proposed regularities we suggested the medium parameters changes dependences and momentum and energy characteristics, the resistance of the medium on which the formation hazards equation were made.A device for rock mass overloading in a large volume, with a reduction of the hazards emission into working zone by two rates was suggested.Key words: cargo flow, safety criteria, the conveyor unit, the porosity of the medium, the flow state, fluent. 1.IntroductionInternational practice recommends conveyor transport for conditions of high power open pit mineral deposits.Advantages are threading movement of raw materials, a relatively large length of transportation, the ability of bulk material movement angle to 20° which allows reducing the delivery path compared to rail and automobile road 6-8 and 3-4 times, increase the height of the mining face and apply the technique of greater productivity.However, at the same time there is an increase of shattered rock mass hazards allocation and creation of the emergency conditions of intermediate filling containers intended
