OPERATION ANALYSIS OF BLAST HOLE DRILLING EQUIPMENT IN KRASNOYARSK REGION AND KHAKASSIA OPEN PITS
The Purpose of the article is to analyze the operation efficiency of mining equipment in order to reduce the cost of blast hole drilling. Methods. Operating data collected in the open-pits of the Krasnoyarsk region and Khakassia have been given a statistical research. Results. Based on industrial researches the operation efficiency of drilling equipment of a number of mining enterprises of the Siberian region including “Polyus” JSC, “RUSAL-Achinsk” JSC, Gorevsky Mining and Processing Plant as well as Chernogorsky, East-Beysky and Izykhsky open casts (Republic of Khakassia) has been analyzed. Conclusion. Domestic drilling rigs with an electric drive are less mobile and efficient than their foreign analogues. However, significantly lower cost of equipment and low specific drilling cost of 1 linear meter of a hole counterbalances this drawback.
