Safety coal storage

Coal can be stored in outdoor stockpiles, in bunkers or in silos. It is usually supplied in the form of "washed smalls" and suitably large discharge cross-sections at bun)cer outlets, etc. should be provided in order to prevent choking, because the coal has poor flow properties. The requisite storage capacity will depend on local conditions and on the rate of fuel consumption of the works. Safety regulations applicable to coal storage must be duly complied with. 

Accumulators in increased safety - e - cover traction batteries for locomotives in coal mines (see Fig. 6.4) as well as batteries for forklifts in chemical plants or other transportation vehicles running in hazardous areas powered by their own energy storage system. Much smaller accumulators are used as a mains-independent power source for handlamps and caplamps (Fig. 6.65) used in potentially explosive atmospheres. 

The greater the amount of carbon dioxide injected, the more will return to the surface with the methane. This creates the need for a gas-separation plant of the type shown in Figure 3.2. The removal of carbon dioxide from oil is much simpler than from methane, which is why enhanced oil recovery is practised more widely than enhanced gas recovery. With an extensive coal seam, it will be necessary to drill injection and extraction wells every few hundred metres or so. These, together with the associated gas compressors, distribution pipes and pumps, access roads, etc., will turn a rural landscape into an industrial site. When the operational/safety issues and the extent of industrialization become fully appreciated, not to mention the impact on the ecological habitat, there may well be local opposition to the recovery of coal-bed methane - with or without carbon dioxide injection and storage. 

Coal mine gas (called Coal bed Gas) is a kind of associated gas from the coal seam in coal mine exploitation process in different forms, which is one of the main reasons of the coal mine accident. As the first fatal factor in coal mine, the gas accident not only causes a large number of casualties and huge economic losses, and imperils the safety of coal mine production seriously once it occurs. Gas concerns the major issues of environmental pollution, the greenhouse effect and the future of new energy. It can be used after recovered rapidly if the coal mine gas develops, storages and transports high-efficiently in moderate environment. Meanwhile it will be reduced that the cost, the hidden safety trouble and the gas emission pollution to the environment. Thus it is badly in need of a new type of gas utilization technology to make up for the current technical defects. Hydrate method is an optional way.

Almost all types of coal may ignite spontaneously in snitable environmental conditions. This leads to serions safety problems as well as economic losses for coal mines and storage areas. The determination of the liability of a coal type to spontaneous combustion is qnite important in dealing with the problem before, during, and after mining. 

Special safety precautions are not necessary for coal that is to be stored for only a few days, as in transfer or transhipment stockpiles. For longer-term storage, however, the coal should be deposited in layers which are each well compacted with the aid of rollers or crawler-mounted vehicles, so as to minimize the entry of atmospheric oxygen to the interior of the pile. Alternatively, the coal should be deposited in a thin layer and as loosely as possible, so that the heat evolved by oxidation can be quickly dissipated [22]. 

As a rule, for reasons of environmental protection and safety, cement works operate with relatively small coal stocks if they can rely on regular deliveries. Under these circumstances no elaborate storage installations are required. Stocks corresponding to about 30 to 60 days consumption are normally held at the works. 

The industrial hygiene data collected demonstrated that there were no detrimental human, health or safety factors associated with the storage or handling of the tire chips at the plant. There were no noticeable odors from the tire chips, either inside or outside the plant, and the results of testing indicated there were no significant worker hazards associated with tire chip burning when compared to burning coal alone. 

The Ministry of Power publishes the reports of the Electricity Council, Gas Council, National Coal Board and special reports such as The Efficient Use of Fuel. The Ministry of Labour issues reports on factory inspection, industrial health, and the series of pamphlets on Choice of Careers. Much useful information is contained in the Safety Health and Welfare series such as No. 8, Toxic Substances in Factory Atmospheres. The Ministry of Agriculture, Fisheries and Food s Circulars are valuable and include items such as Chemical Compounds used in Agriculture and Food Storage.
