  • Coal Mining PNR

    For coal mining and coal handling processes (and similar applications of products such as gravel) spray nozzles are used most of the time for coal and dust suppression applications. Full cone and flat fan spray nozzle patterns are the most commonly used nozzles as well as air-assisted atomisers and ultrasonic atomisers. In addition to these, other products that can be of interest are in-line filters, pipe

  • Effect of spraying on coal dust diffusion in a coal mine

    01.09.2020· Nozzles can be divided into three types according to the shape of the spray field they form: fan nozzles, solid cone nozzles, and hollow cone nozzles (as shown in Fig. 5). In general, solid cone nozzles are more widely used in coal mine spraying equipment because of their large, atomizing coverage area. Some of the mechanical atomizing nozzles commonly used in coal mines, as listed in

  • Coal Producer Improves Safety and Opens New Mining Areas

    FloMax® air atomizing nozzles have improved safety in the mine and allowed the coal producer to mine areas that were previously untapped. Because the production value of a single continuous miner can far exceed US$50,000 per day, the additional coal produced in the mine resulted in a payback period of less than two weeks. Since the original installation, three additional continuous miners

    Kuznetsk coal basin (7). Output and costs per ton were much more favorable than with conventional mining and the methods were applied in many different mining condi­ tions across the Soviet Union (8). As a result of these trials, experiments in hydraulic coal mining began in the United Kingdom (9), the United States (10), China

  • Effect of spraying on coal dust diffusion in a coal mine

    Aimed at effectively controlling coal dust pollution in the mining face of a coal mine, this study first conducted a theoretical analysis and then combined a spraying experiment and a numerical simulation to perform an in-depth examination of the atomizing characteristics and dust suppression performance of a coal cutter external spraying device. Based on the experimental spraying results, the

  • Hydraulic mining Wikipedia

    Hydraulic mining is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal. Hydraulic mining developed from ancient Roman techniques that used water to excavate soft underground deposits. Its modern

  • How to control dust in the mining industry

    Other factors affect nozzle performance besides its configuration. Water pressure, measured at the pump by a gauge is vital because it governs many aspects of spray intensity, distance, and pattern. The angle, number, and performance tables of nozzles also determine how effectively they can suppress dust in a given area. Narrow spray angles, for example, provide a more intense and thorough spray pattern. In many cases, you will need multiple nozzles
