Dissatisfaction with work boot design is common in the mining industry. Many underground coal miners believe their work boots contribute to the high incidence of lower limb injuries they experience. Despite this, the most recent research to examine underground coal mining work boot satisfaction was conducted over a decade ago. This present study aimed to address this gap in the literature by as...

With the fast development and utilization of underground space resource in cities, the spatial distribution of urban underground pipelines becomes more and more complex. How to efficiently utilize the latest technology, realize underground space resources' management, visualization, layout optimization and mine applications, are challenging issues in current digital city development. Taking int...

Constructing and operating a large underground facility for the geological disposal of high-level radioactive waste decades will cause changes in environment around facility. Since permeability heterogeneity fractured granite Japan are higher than those Europe, disturbance to groundwater due tunnel excavation is expected be complex. Therefore, modeling fracture characteristics important accurat...

Cleaning up and disposing of approximately 50 years of nuclear waste is the main mission at the U.S. Department of Energy’s Hanford Nuclear Reservation, located in the southeastern part of the state of Washington. A major element of the total cleanup effort involves retrieving, processing, and disposing of radioactive and hazardous waste stored in 177 underground storage tanks. referred to as t...

This paper studies the issue of tax evasion in the context of the underground economy. A dynamic general equilibrium model is built where individual households and entrepreneurs decide rationally whether to go underground and under-report their earnings. These behaviors affect tax revenues, which are used to finance productive public services. This model is applied to the Czech Republic, becaus...

There is a relationship between the economic requirements for development of oil and gas facilities in oil-producing regions North environmental problems sustainable development. One ways to solve this problem wider use underground storage both reducing peak loads Unified Gas Supply System by collecting storing previously flared associated petroleum gas, burying large volume industrial emission...

In the context of feasibility study for geological disposal radioactive waste, this work focuses on numerical modeling hydromechanical response and induced damage zones around an experimental gallery at underground research laboratory (URL) Bure in France. A new phase-field method is first proposed by considering two independent fields order to easily describe both tensile shear cracks. The ext...

Within the context of deep geological radioactive waste disposal, French National Radioactive Waste Management Agency (Andra) is conducting a research program including in-situ experiments at Meuse/Haute-Marne Underground Research Laboratory (MHM URL), which aims to demonstrate feasibility constructing and operating High Level (HLW) disposal facility in Callovo-Oxfordian (COx) claystone formati...
