Several techniques are also known for measuring strain along optical fibres, this can be desirable in a range of circumstances, e.g. in systems with space constraints or where many measurement points are required. Optical fibres, however, are known for being fragile and having a low tensile strain limit.This paper presents a realisation of a high capacity, directional torque and compression sensor using a single optical fibre with multiple Fibre Bragg Gratings (FBGs). Our design parameters adjust the sensing range to the expected forces and showcases an application for the mining and drilling industry.","PeriodicalId":121199,"journal":{"name":"2017 2nd International Conference for Fibre-optic and Photonic Sensors for Industrial and Safety Applications (OFSIS)","volume":"179 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116062159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Micro-mechanics of deformation of rock and precursors to major failure or rock bursting mechanisms can be best understood in the laboratory under controlled stress conditions. An experimental program was envisaged to understand and monitor the stress induced cracking events during compressive loading of two rock specimens of different geometry shapes. High frequency Fibre Bragg Grating (FBG) based optic fibre interrogator system was used to monitor Acoustic Emission (AE) of rock specimens under two different test configurations. The FBG sensors picked up high frequency AE events of rock cracking, and these captured AE events predominantly coincided with the load drops in the load-time/deformation diagrams. These high frequency FBGs optic fibre interrogator systems could be used as an alternative to PZT/geophone based systems and they can be safely deployed in underground mines and AE can be monitored over a long distance with least transmission loss.","PeriodicalId":121199,"journal":{"name":"2017 2nd International Conference for Fibre-optic and Photonic Sensors for Industrial and Safety Applications (OFSIS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125322819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A passive fibre optic cable provides accurate temperature measurements along the length of the conveyor belt, which enables an effective and cost-effective monitoring of even very long conveyor routes. Fires and overheating, which can occur during operation and lead to serious damage and long downtimes, are quickly detected and localized to within one-meter accuracy. The necessary countermeasures can be quickly activated. Heat detection for hot rollers requires a proper installation of the sensor cable and configuration of the alarm zones and analyses. This paper is based on conveyor belt tests and case studies, and describes the potential of fibre-optic based DTS technology with regard to fire and hot-roller detection along conveyor belts.","PeriodicalId":121199,"journal":{"name":"2017 2nd International Conference for Fibre-optic and Photonic Sensors for Industrial and Safety Applications (OFSIS)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114251788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although an advanced system based on fibre opticsensing (FOS) technologies have increasingly drawn attention by mining industry, their applications in coalmines are still challenged by a number of factors, such as the survivability in large strain range, appropriatefibre encapsulation and installation methods and minimisation of measurement errors due to the straintransfer loss. This paper presents the results of preliminary experiment in developing fibre optic based roofstability monitoring system forunderground coal mines, including the validation of surface mounting bareFBGs in rock mass compressive test. The accuracy of the bare FBG sensors in measuring compressivestrain for rock mass are validated against the electrical strain gauges and linear variable differentialtransducer (LVDT). Using the stress-strain curve and Young’s modulus of the standard samples as areference, the experiment results show that the bare FBG and electrical strain gauges can provide accurateand reliable compressive strain measurements for material with different mechanical properties.","PeriodicalId":121199,"journal":{"name":"2017 2nd International Conference for Fibre-optic and Photonic Sensors for Industrial and Safety Applications (OFSIS)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114082923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
