For deep coal mining engineering, the rock surround laneways would experience several damages. The broken rock is a special composite medium by rock, fracture which is filled with water or air. Although, a lot of researches about the electromagnetism of rock have been done, mostly is about intact rock. And the EM wave field propagating in the stochastic broken medium was not clearly mastered too. Generally, it depends on empirical judgments to identify the boundary and determine the range of the broken rock zone. So, the authors try to establish a theoretical permittivity formula of the stochastic broken rock by analytical analyses, and the bulking factor of Rock Mechanics is introduced into the formula. Then, orthogonal numerical simulations, considering of fracture length, aperture, volume fracture number and moisture, are carried out to modify the theoretical permittivity formula. Furthermore, a numerical model of a laneway surround by a stochastic Broken Rock Zone(BRZ) is established, and the GPR profile along the inner surface of the laneway is calculated, which could be of help to identify the BRZ boundary in GPR profile. Engineering example of GPR exploration and borehole imaging are also given to illustrate the feasibility of GPR utilized on the BRZ detection in deep coal mining engineering.","PeriodicalId":212710,"journal":{"name":"Proceedings of the 15th International Conference on Ground Penetrating Radar","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125370052","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}

Construction of the tunnel was completed in 1996 and it carries a substantial volume of traffic between two major areas of Medway. The construction of the tunnel is an “immersed tube” tunnel type that connects a number of segments at immersion joint points. This investigation reports on the use of a 2 GHz GPR antenna system in establishing structural details of the tunnel roof at immersion joints. The processed data compiled as a result of this investigation provided much needed information to tunnel engineers for forthcoming maintenance planning purposes. It also provided ample information in confirming the rather doubted construction design drawings/plans originally produced. The reported results are conclusive in terms of construction materials used (information was not originally available and needed confirmation) as well as establishing the required information on the formation of the tunnel roof joints. The presentation is complemented by providing detailed information of the complex process of adopting the GPR systems used in this endeavour.","PeriodicalId":212710,"journal":{"name":"Proceedings of the 15th International Conference on Ground Penetrating Radar","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114551244","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}

In hydrological applications, the resulting velocity models are often used to estimate hydrological material properties such as soil water content or porosity. However, uncertainties in the inverted velocity and in the employed petrophysical models are typically ignored. We present a workflow to appraise uncertainty and nonuniqueness issues inherent to VRP traveltime inversion and to quantify the influence of these issues on the following petrophysical translation. Our strategy relies on an efficient global inversion approach, which results in an ensemble of velocity models explaining the data equally well. For estimating water content and porosity, we use the entire ensemble of velocity models which results in an ensemble of possible petrophysical parameter distributions. In addition, this Monte-Carlo procedure allows us to investigate the impact of uncertainties in the employed petrophysical model by using a variety of appropriate translations. Using synthetic VRP data and a field example, we demonstrate the applicability and the potential of the proposed workflow.","PeriodicalId":212710,"journal":{"name":"Proceedings of the 15th International Conference on Ground Penetrating Radar","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129282905","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}
