Development and Research of Special Excavator Buckets for Mining Oil-bituminous Rocks

Year: 2026

Type: article

Abstract: Given the shortage of petroleum bitumen in the Republic of Kazakhstan, the use of local bitumen-containing rocks is becoming increasingly relevant, which requires the development of specialized mechanization tools. In this paper are discussed the special excavator buckets designed for year-round extraction of rocks with a bitumen content of up to 25%. The design features of the bucket that reduce resistance during digging and unloading are described. Calculations of resistance, chip thickness, operation duration, and productivity of the EO-4121 excavator at different temperatures and bitumen contents were performed. It is shown that unloading becomes more difficult when the bitumen content exceeds 18.2%. A comparison of the calculated and experimental data confirmed the high accuracy of the models used.
