Coke (fuel) Raw coke. Coke is a fuel with a high carbon content and few impurities, made by heating coal in the absence of air. It is the solid carbonaceous material derived from destructive distillation of lowash, lowsulphur bituminous coal. Cokes made from coal are grey, hard, and porous.

One usage of limestone is to avoid coal dust explosion in coal mines. Methane gas is a colorless, odorless, flammable gas that is liberated naturally from coal seams. Methane is particularly dangerous if it reaches concentrations between approximately 5% and 15% in air where the mixture becomes explosive.
INTRODUCTION. Silica is the second most common mineral on earth. Chronic inhalation of silica causes silicosis ().Inhalation of crystalline silica occurs mostly in occupational settings, particularly such occupations as mining, sandblasting, stone cutting, surface drilling, pottery making, silica flour mill operations and other occupations in which silica dust exposure occurs.
Tumbled Jet (Russia) These are polished pieces of Jet. Jet is organic in origin and is actually compacted organic material that is fossilized. It is surprisingly light in weight and comes from a variety of countries such as the USA, Russia, England, and Turkey to name a few. For a grounding
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic . At room temperature and pressure, another solid form of carbon known as graphite is the chemically stable form, but diamond almost never converts to it. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are utilized in major ...
You can find coal on exposed stone at the surface, however to get lots of coal, you must dig underground a bit. If you can't find any at first, go get some logs, then bake them in a furnace.
Common ways to reduce dust exposure in the construction industry are by the use of (local) exhaust ventilation systems, wet dust suppression by use of (cooling) water, use of personal protective equipment or influencing worker behaviour by training and education.
Silicosis is a lung disease caused by breathing in tiny bits of silica, a mineral that is part of sand, rock, and mineral ores such as quartz. It mostly affects workers exposed to silica dust in occupations such mining, glass manufacturing, and foundry work. Over time, exposure to silica particles causes scarring in the lungs, which can harm your ability to breathe.
Sulphide dust explosions An underground mining hazard involving the spontaneous combustion of airborne dust containing sulphide minerals. Sulphur dioxide A gas liberated during the smelting of most sulphide ores; either converted into sulphuric acid or released into the atmosphere in the form of a gas.
Dust exposure. In coal mining, the extraction, crushing, and transport of coal can generate significant amounts of airborne respirable (extremely fine) coal dust. Dust less than 10 microns in size (cannot be seen with the eye).

Stone Processing. Usually in stone crushing plant, Jaw crusher is used as primary crusher machine, when big stones are crushed smaller by Jaw crusher; they are transferred to Impact crusher or Cone crusher for secondary or tertiary crushing, then go through the stone shaping machine for getting cubic size.
Miners/Health And Hygiene. Description: "Respirable silica dust exposure has long been known to be a serious health threat to workers in many industries. Overexposure to respirable silica dust can lead to the development of silicosis a lung disease that can be disabling and fatal in its most severe form.
