Rock Breaking Mechanism of Percussive and Rotary Tools
Rock drilling and breaking mechanism was researched to indicate physical processes of the rock breaking,create the work-energy conversion relations during the rock breaking,which was used to predict the breaking results(drilling speed)and as a guidance for the design of breaking tools.For nearly 100 years,the mechanical analysis was made on the physical process of the rock breaking at various facets,and some theoretical results were obtained.However,those researches,have difficulties in acceptable applications in engineering yet.There are various rock breaking methods,and the breaking mechanisms are closely related to the breaking methods.The article focuses on the rock breaking mechanisms tightly tied with the rock breaking.
