HAZOP (Hazard and Operability Studies) is an important tool in the study of chemical process plant safety and loss prevention, and formed a key component in the education of chemical engineers.
Canada's Deadliest Mining Disaster. The disaster at the Hillcrest Collieries mine on the morning of June 19, 1914, provides a poignant illustration of the dangers of coal mining. The mine had sat idle for two days due to overproduction, but on that morning 237 men descended underground to resume work; only fortysix emerged alive.
Major mine hazards include roof falls, rock bursts, and fires and explosions. The latter result when flammable gases (such as methane) trapped in the coal are released during mining operations and accidentally are ignited.

Coal is the dirtiest fossil fuel and has contributed more to global warming than either oil or gas. By one estimate, 46% of all manmade greenhouse gases spewed into the atmosphere since 1750 have come from coal, raising seas that threaten major cities and supercharging hurricanes. The world has responded.
There are a number of negative health effects of coal that occur through its mining, preparation, combustion, waste storage, and transport. Negative health effects from coal use within the include: [1] Reduction in life expectancy ( particulates sulfur dioxide heavy metals radionuclides, etc.) Respiratory hospital admissions ( particulates ...
The scheme used in physical coal cleaning processes varies among coal cleaning plants but can generally be divided into four basic phases: initial preparation, fine coal processing, coarse coal processing, and final preparation. A process flow diagram for a typical coal cleaning plant is presented in Figure
The combustible nature of crushed coal poses a fire hazard in the conveying system. Frictional resistance between idlers and rollers, insufficient lubrication, belt misalignment, and faulty bearings can generate sparks or heat, which can ignite the crushed coal. 3) OnSite Power Plants. Cement manufacturing is a very energy intensive process.
The plant's largest battery, a structure containing dozens of coke ovens, was shut down after the blast. Company officials said it was operating at a reduced rate Thursday and expected it to be fully operational in a week. The rest of the plant was operating normally. Fourteen employees and six contractors were injured in the blast.

Coal dust in coal handling and processing facilities. (Note: OSHA Standard 29 CFR (v)(11)(xii) addresses control of ignition sources at coal handling operations in electric power plants. The Mine Safety and Health Administration (MSHA) has authority in some areas involving coal crushing and conveying.
Coal preparation. As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for the equipment and miners.
