Abstract

The paper presents an innovative strain and temperature measurement method using the fibre Bragg grating (FBG) technology to monitor the design and operating safety of selected underground mining machinery and equipment. The system is based on the fibre Bragg grating (FBG) sensors or sensors using the optical time domain reflectometry (Optical Time Domain Reflectometry) technology. The essence of the solution is to introduce FBG sensors into the structure to make them act as its пїЅnervous systemпїЅ. Compared to classical monitoring methods, the FBG technology has a number of significant advantages. Owing to the fact that white light is used as the working medium, the method is spark-safe and characterized by high measuring accuracy at the level of 1 ?strain and by good resistance to fatigue. It also makes it possible to reduce the number of measuring points considerably and automate the monitoring process. Tests were performed of elements of the hoisting machine brake, the guide rope and of components of a new shearer. The testing results prove that FBG-based monitoring techniques may substantially improve the design and operating safety of underground and surface mining machinery and equipment.
