... ABSTRACT: Underground mine pillars are typically supported using rockbolts, wire mesh, shotcrete liners, or a combination of these methods to enhance stability and maintain their load-bearing capacity. The design of these supports is generally based on field experience, which is often site...

... ABSTRACT: An adaptive meshing technique is detailed which is suitable for large scale finite element modeling of solution mines. The resulting meshes of "bricks" are fully compatible (portable), that is no hanging nodes result, requiring multi-point constraints to satisfy continuity...

... for such environments. For the sake of consistency, the authors have adopted the terminology proposed by Windsor and Thompson (1992) as presented in Villaescusa et al (2023). A Ground Support Scheme is therefore defined as a combination of a surface support system, composed of plates, mesh, liner or shotcrete...

... modelled in a discrete fracture network. By contrast, heat and stress (TM processes) are mediated via the rock mass, and thus best represented as a continuum. Here, we present an approach using dual, coincident meshes, each simulating the relevant processes in their ‘natural’ media. A sequential coupling...

.../quartz sand ratio, dynamic conductivity decreased gradually with closure pressure increase. Under formation closure pressure, the conductivity of quartz sand with the same proppant size is lower than that of ceramic proppant, and the average conductivity reduction ratio is 36.6% and 45.5% for 30/50 mesh...

.... The results presented herein address performance and accuracy issues, stress parameter setup in fracture propagation and thermal front evolution models. It was found that working with multiple meshes in numerical simulation runs is advantageous because it enables dealing with more complex scenarios while...

However, due to meshing limitations, the MEM is typically derived from simplified geological frameworks and does not relate with static and flow simulation models anymore. To overcome these difficulties, we have developed a general solution to readily assess...
