The Impact of Cutting with a Shearer on the Conditions of Longwall Ventilation [PDF]
Energies, 2021 In coal mines that are exploiting methane-saturated seams, high-level emission of methane is often the basic limitation for modern and high-efficiency longwall complexes. This paper presents selected observations and tests carried out in the Cw-4 longwall in seam 364/2 of the Budryk mine, which belongs to JSW SA. To observe the methane levels in the Cw-

The Present State of Surface Conditioning in Cutting and Grinding [PDF]
Journal of Manufacturing and Materials Processing, 2021 All manufacturing processes have an impact on the surface layer state of a component, which in turn significantly determines the properties of parts in service. Although these effects should certainly be exploited, knowledge on the conditioning of the surfaces during the final cutting and abrasive process of metal components is still only extremely ...
