“…Coal dust was placed on the bed, as well as in special gutters on the working's sides. The explosion was carried out by blasting a stoichiometric mixture of air and methane, which was created in the dead-end part of the adit [8].…”

“…A large body of scientific work addresses the processes occurring during explosions inside mining workings. Study [8] simulated the gas explosion parameters and the virtual flame movement within underground voids. Paper [9] established the effective parameters of the macro kinetics of hydrocarbon combustion under a deflagration and detonation mode in the numerical calculation of emergency explosions in mining workings to suppress the shock wave in the workings' voids.…”

“…To achieve an adequate safety level, equipment must be designed according to safety principles, and constructed following certain constructive rules, or Protection Modes (Tables 3 and 4) [24]. On the other hand, there are three different protection measures for mining, specially designed according to the characteristics of underground mining [25]:…”

Implementación de las normas ATEX en el contexto de la actividad minera en Colombia Implementação das normas ATEX no contexto da atividade mineira na ColômbiaLinda Mishell Jaramillo-Urrego * Jorge Martín Molina-Escobar ** Javier García-Torrent *** Ljiljana Medic-Pejic **** AbstractMining in Colombia is regulated by the Mining Safety Code, and although it had not been updated since 1987, the references on safety that the code has owned were based on international standards. However, these references do not have a mandatory adoption, and despite a strong component on occupational safety and health, Decree 1886/15 continues to show a rough technical content that could consent the extension of mining disasters associated with explosions in Colombia. This article specifies the international mine safety regulations, and critically analyzes the absence of its applicability in the country. Although the national outlook is discouraging because of the lack of rigor from governmental entities in enforcement, mining in other countries has improved in safety as a result of implementing standards that ensure quality operations and procedures, machinery, and human resources, decreasing mining disasters.Keywords: Accident Prevention; Combustion; Explosions; Explosive atmosphere; Occupational safety; Standards review.

“…The proper management of risk in underground mining, especially coal, is critical to avoid undesirable situations that could lead to tragic accidents, such as fires or explosions [1,2]. Many preventive and corrective measures have been proposed and developed over time [3], but there are still important fatalities in these types of activities [4]. Fires in coal mines depend on the intrinsic characteristics, either thermal or physical, of the available fuel sources (coal, wooden supports, and equipment, among others); the ventilation system implemented [5]; the size of the drifts and openings [6,7]; and the operational conditions [8].…”

A laboratory-scale analysis using coal from an underground mine was carried out, emulating a mixture from the gob area in an actual mine, consisting of waste, coal, and free space for the flow of air. Experimental tests and computational fluid dynamics modelling were done to define and verify the behavior of the collapsed region in a time-dependent analysis. In addition, the characteristics of coal were defined, regarding the self-combustion, combustion rate, and pollutants generated in each stage of the fire. The results achieved are useful for determining the behavior of the collapsed area in full-scale conditions and to provide valuable information to study different scenarios of a potential fire in a real sublevel coal mine regarding how the heat is spread in the gob and how pollutants are generated.
