Research to the Tension Monitoring Instrument of Bolt and Cable in Multi-Point

Abstract:

Since safety of roadway and steady of rock depend on bolt and cable supporting quality ^[~[, it is important to evaluate timely bolt and cable supporting quality that monitors tension state of bolt and cable. With separated type design, the monitoring instrument, which is to monitor tension of multiple survey point and separation type Bolt and Cable, is made up of tension of bolt and cable sensor and secondary measuring instrument. This paper focuses on the composition and the basic principle of the tension of bolt and cable sensor structure, the composition of secondary measuring instrument structure and functional partition of the chips and circuit theory of the monitoring instrument. This paper introduces the concrete implementation way and the conditions of usage of the monitoring instrument and introduces the monitor in the application of the auxiliary slot of 22301 working face of Shen Dong coal group Shi Ge Tai ore.
