Based on the principle of the linear relation between nut kinetic frictional tightening torque and axial pre-tightening force of anchor stem which is indirectly measured through measuring the tightening torque,the intrinsically safe portable dynamometer for anchor stem in mine is developed with the ultralow-power MSP430 serial SCM and peripheral circuit.

A mechanics model of dynamometry bolt was given and it was shown that dynamometry bolt mainly bear tension and torque in real application.

The working relationship map between dynamometry bolt and surrounding rock is proposed.

Base on the analysis and research on the temperature strain crossing sensitive mechanism of the optical fiber and optical grating,an optical Bragg and optical grating bolt dynamometer was designed and developed base on a cylinder transmission.

The dissertation discusses the fundamental knowledge about the force sensor for pulling force measurement of anchor rope (FSPFMAR) as well as Vibrating wire sensing technology .

Authors make use of JL—MG bolt integrity testing survey meter to have non—destructive test for Jingying highway bolting integrity according to stress wave principle.
