Study on Thermal Energy Conversion Theory in Drilling Process of Coal and Rock Mass with Different Stresses
In view of the problem that the evolutionary mechanism of bit temperature during the drilling process is still unclear and the influencing factors are complex, this paper analyzes the causes of heat generation and the factors of heat production when the drill bit interacts with the coal and rock mas...
