The Large Eddy Simulation turbulence model was selected because it shows accuracy compared to the widely used Reynolds’ averaged models for the scenarios investigated in the experiments. Experiments were also conducted to evaluate the selected numerical models. The combinations of eight FLSFs and five HDSFs will cover a wide range of space dimensions where flammable gas could accumulate. In this paper, the impact of scaling on explosion overpressures is investigated by employing two scaling factors: The Gas-fill Length Scaling Factor (FLSF) and the Hydraulic Diameter Scaling Factor (HDSF). Thus, the scale effect on explosion parameters is worth investigating. The dimensions of a confined space where explosions could occur vary significantly. Computational Fluid Dynamics (CFD) techniques are sophisticated in simulating explosions in confined spaces specifically, when testing large-scale gaseous explosions, such as methane explosions in underground mines. Gas explosion is the most hazardous incident occurring in underground airways. Authors may use MDPI'sĮnglish editing service prior to publication or during author revisions.

This Special Issue will focus on cutting-edge research, recent innovations, and advanced technologies in mine ventilation and monitoring systems with respect to enhanced performance and reliability, health and safety improvements, energy and cost savings, and mine productivity. Underground mine workforce safety and workplace productivity rely significantly on the performance of mine ventilation and monitoring systems. Underground mines need to be equipped to accurate, real-time, and intrinsically safe monitoring systems to be able to continuously assess the condition of a mine ventilation system. The main purpose of mine ventilation systems is to maintain thermal comfort of underground personnel, remove heat from equipment, dilute mine contaminants, and provide fresh air for personnel to breathe.
