TECHNIQUES OF OPTIMIZATION OF DRILLING AND BLASTING ON THE GOLD ORE FIELD ALBAZINO



Albazino — a rich deposit of stubborn gold, is an important part of the Amursky hub: the Amursky Mining and Metallurgical Combine. Located in the Far East of Russia, the Amursky hub became the first complex of autoclave leaching of gold concentrates in Russia. The article describes the geological characteristics of the Albazin gold ore deposit. According to the «Atlas of multifactorial models of gold ore deposits in the Far East», structural and morphological typification of Albazinsky ore field was revealed. It is established that the structural type of the deposit refers to the vein-stockwork and carcass in the dikes of different composition. The method of optimization of drilling and blasting operations at the Albazino gold ore deposit is analyzed. It is proposed to drain the wells by draining the water from the massif over artificially disturbed zones by creating a drainage contour gap in the rear and side parts of the operating unit. Contour slots create blasting of contour wells with a diameter of 165 mm. The economic justification of the proposed technology is given.
