Abstract In view of the present mining roadway support after the disadvantages of traditional anchor detection method, in order to cover the state coal as the engineering background, according to the actual conditions, anchor power instrument for nondestructive testing of bolt support for on-site monitoring and evaluation was adopted. The measured results showed that the detecting instrument testing data and bolt parameters varied within 6%, the nondestructive testing method could satisfy the requirement of detecting in at the same time, optimization roadway supporting method has obtained the good economic efficiency, realized the mine safety and efficient production.
