Enhancement of Powered Cleaning Equipment with the View of Mining and Geological Conditions

[摘要] A method aimed at the enhancement of powered cleaning equipment, in particular, the section of powered support and armored face conveyor with the view of changing both mining and geological conditions is considered. The article offers the hydraulic prop operating characteristics of powered support sections with the separated functions of rock pressure protection and control, as well as non-pulse control of the resistance of hydraulic props of the support sections to the lowering of roof rocks and the structure of armored cutting conveyor with the curved flight (unit) capable of forming a support surface along the ground for directional movement of powered cleaning equipment and control the layer pressing by means of cutting. The whole unit is aimed at the adjustment of position of equipment along the ground, as well as control of the rock pressure and the ground pressing. All this enhances the operability of equipment as a whole.
