【 摘 要 】

Advantages and disadvantages of tangential rotary picks widely used in mining machines are described. A prospective line of picks design improvement has been found based on a change in the principle of destruction. A new design of blade-type cutting picks with a reinforcing tip is proposed having extended service life, requiring less energy for rock breaking, reducing yield of fine dust and increasing the grade of the mined coal.
