Experiment-based Investigations on Explosion Behaviors of Coal Dust-inertant Mixtures

open access: yes工程科学与技术, 2012
:To gain an insight into the explosion behavior of coal dust-inertant mixtures, systematic experiments were carried out on explosion severity (the maximum explosion pressure, the maximum rate of pressure rise and the combustion duration), sensitivity ...

Investigation of the Minimum Ignition Energy Required for Combustion of Coal Dust Blended with Fugitive Methane

open access: yesFire
Ventilation Air Methane (VAM) significantly contributes to global warming. Capturing and mitigating these emissions can help combat climate change. One effective method is the thermal decomposition of methane, but it requires careful control to prevent ...

Evaluation of parameters to determine the degree of coal dust explosibility [PDF]

open access: yes, 2014
Coal dust is highly explosive and caused dozens of victims in Colombia. In this research the most important and direct influence on coal dust, especially those that cause combustion and explosion inside the mine factors were analyzed; is important to ...

Comparative study of the explosion pressure characteristics of micro- and nano-sized coal dust and methane–coal dust mixtures in a pipe

open access: yesInternational Journal of Coal Science & Technology, 2020
Coal dust explosion accidents often cause substantial property damage and casualties and frequently involve nano-sized coal dust. In order to study the impact of nano-sized coal on coal dust and methane–coal dust explosions, a pipe test apparatus was ...

Trends in Respirable Coal Mine Dust Concentration (mg/m3) based on Coal Miners’ Occupational Designation: An Analysis of the MSHA Coal Dust Samples Data Set (2000-2022)

open access: yes, 2023
Rates of Coal Workers\u27 Pneumoconiosis (CWP) have recently increased in prevalence over the past 20 years. Recent regulation (Phase III) by the Mining Safety and Health Administration to lower the coal dust standard to 1.5 mg/m3 has been mandated to ...

Prediction of dust concentration in open cast coal mine using artificial neural network

open access: yesAtmospheric Pollution Research, 2012
AbstractCoal dust is a major pollutant in the ambient air of coal mining areas. The pollution due to open cast mining is more severe than pollution due to underground mining. Prediction of ambient concentration of pollutants should be known to implement any control techniques to reduce their concentrations. In this paper, three models were developed to
