Abstract:

In coal mines, the mixture of coal dust and gas is more ignitable than gas alone, posing a high explosion risk to workers. Using the explosion tube, this study examines the explosion propagation characteristics and flame temperature of low-concentration gas and coal dust mixtures with various particle sizes. The CPD model and Chemkin-Pro 19.2 simulate the reaction kinetics of these explosions. Findings show that when the gas concentration is below its explosive limit, coal dust addition lowers the gas’s explosive threshold, potentially causing an explosion. Coal particle size significantly aff

Abstract:

Accidents caused by domestic gas explosions occur regularly enough. Gas explosion accidents indoors are defined as deflagration explosions. The formation of an explosive cloud depends on many factors inside the building. To understand why the buildings in one case withstand an explosion but collapse in another case, more precise design models and methods of their realization are needed. We used numerical modeling to calculate the blast load intensity and find out the impact of the actual environment parameters. For the model verification we referred to the full-scale experiment on the deflagra

The suppression effect of inert powder on gas-induced suspension coal dust explosions was investigated using a semi-closed pipeline experimental platform.

Abstract:

In coal mine goafs, spontaneous combustion of coal can result in methane accumulation, which raises the danger of methane explosion disasters. As an atmospheric control tool, ventilation is applied to ensure air quality for avoiding disasters in underground mines. However, during the process of the spontaneous combustion of coal in coal mine goafs, the impact of ventilation dilution on the possible methane explosions induced by coal combustion has not been well investigated. In this study, a validated gas flow model for the spontaneous coal combustion environment in goafs of coal mines is adop

Abstract:

Excess pressure is the main indicator characterizing the magnitude of explosive loads during emergency gas explosions. The value of this parameter and the entire accident scenario as a whole directly depend on the concentration of gas entering the room. Any typical room is characterized by the presence of two processes: laminar and turbulent diffusion. The laminar diffusion coefficient depends on the main characteristics of the gas (pressure, temperature). The laminar diffusion coefficient depends on the main characteristics of the gas (pressure, temperature). The coefficient of turbulent diff

Abstract:

Explosion isolation flap valves are one of the most used explosion protection systems in process industries; research is essential to improve them and to minimise both human and material losses when dust explosions take place. In this regard, there is little knowledge on the effect of bends in the functionality of these protective systems; hence, the main aim of this work is to bridge this gap. Large-scale dust explosions were performed, using three different types of dust: metal dust and two types of organic dust. In order to analyse the effect of bends in the functionality of these protectiv

Abstract:

To study the law of sizes on gas explosions, numerical simulations of methane–air mixture explosions in spherical vessels were performed. The law of sizes on gas explosions is studied using FLUENT simulations with the [Formula: see text] two-equation turbulent model, the eddy-dissipation-concept model, thermal dissipation at a wall boundary, the P1 model, and the SIMPLE algorithm. The experimental results suggest that under an adiabatic condition without energy loss, the maximum explosion pressures in different spherical vessels are all 0.82 MPa, and the effect on the explosion intensity in sp

Abstract:

In the large-scale underground explosion, the dynamic mechanical behavior of deep rock mass under the coupled loading of the high in situ stress and the explosive stress wave is difficult to study. And the coupled loading of the in situ stress and the stress waves of large-scale underground explosions are hard to simulate. Based on this problem, an experimental device was developed, and a nonexplosive method for simulating stress waves of large-scale underground explosions was presented by us. In the experimental device, the impact energy is provided by the high-pressure gas in the air chamber

Digital simulation of mine fires and explosions is an important stage in the process of developing technical solutions and measures aimed at improving the safety of personnel involved in underground mining. Correct simulation results determine the effectiveness of decisions in the event of an actual emergency situation. In this regard, due attention should be paid to each stage of the simulation, and especially to the initial stage of model parameterization.

The coal mine ground gas transportation system is widely used for gas transportation and mixing preheating in the gas storage and oxidation utilization system. However, gas or coal dust explosions may occur, which could result in heavy casualties and significant economic losses. To prevent accidents in the gas transportation system, the present study takes the gas transportation system of Shanxi Yiyang Energy Company as an example to identify the composition and hazardous factors of the gas transportation system.

Gas explosion accidents in underground coal mines caused a significant number of casualties.

In this way, the data pertaining to explosion flames and explosion pressures at different propagation distances were obtained to investigate the propagation of explosion flames and explosion pressures along the laneway.

The study was conducted in the context of military aggression, where the use of propane-butane by the population of Ukraine for cooking and heating has become particularly relevant due to periodic power outages. This situation creates additional threats, as the fire and explosion hazard of gas cylinders, particularly their depressurization due to critical pressure and temperature increases, is determined by several key factors. Incidents related to gas explosions regularly occur worldwide, causing significant material damage, infrastructure destruction, and, most importantly, human casualties.
