Abstract

The article presents the influence of work conditions of rotary-tangential picks on their wear while compact rocks mining. There was mainly presented the influence of applying high-pressure support and spraying the tangent-rotary tools with water jets on their quantitative and qualitative wear during conducted laboratory tests in comparison to tools operating in dry conditions. There was suggested and presented a solution of holders lubricated with water under pressure to provide proper conditions of tangent-rotary tools work in the clamp. The results of laboratory tests of rotary-tangential picks fixed in the folders were presented and compared with results of picks only supported or sprayed with high-pressure water jets.
