Yorchenco A. Increase of ecological safety of mass explosions in iron ore quarry after a dust is factor

In dissertation an actual scientific task, that consists in set conformities to the law of distribution of dust cloud after the mass explosions in iron ore quarry and level of its ecological danger and development on this basis ecologically effective methods and facilities of reduction of influencing of the troop landing of dust on the state of environment, is decided. The methodical bases of determination of height of getting up of iron ore dust particles under action of thermal factors both at presence of wind are developed, and at his absence. Methods and facilities of reduction of height of getting up of dust cloud and distance of its distribution, which foresee conducting of works after optimization of parameters of borehole charges, and also use, are developed as the printed fabric of rubber cork with the anchor device. The method of defence of environment is im-proved from the troop landing of dust by irrigation of dust cloud on the whole, substan-tiated necessary diameter of drops of water for providing of maximal efficiency of dust suppression, and also necessary volume of water for this. For transportation and splashing of water above the dust cloud of the substantiated use by the special appear-ance of the equipped helicopters. The degree of ecological danger at introduction of the offered methods and facilities of dedustinq measures up "safe".
