Spreading out Dust and Gases, Formed by Blasting Operations at Erdenetiin-Ovoo Ore Open Pit Mine and Application of Remote Control (Firing) System for Blasting
Blasting operations,using large amount of explosives (100~200 tons and over) and specific climate condition around the mines can create problems,associated with toxic gas and dust spreading and safety conditions of the employees.The paper presents methodic,estimates and calculations for spreading out toxic gases and dust,formed by blasting at Erdenetiin-Ovoo ore mine.Determined are safety zone radius for toxic gases,weight of dust,falling down from dust-gas cloud etc.Also,some results of measurement and analyses for chemicals and substances at the mine site by the laboratory of Erdenet Mining Corporation Company are given in the paper.The paper describes basic indices and specifications and advantages of remote control firing system for blasting Rottenbuhler enjinering(R),selected and used at the mine.Estimates of economic effectiveness from introducing remote controt firing system are provided.Conclusions and suggestions,based on test and studies are summarized.
