Hydraulic roof supports control the height, and provide support to the mine roof of the working face during the coal mining process, allowing armored-face conveyors and shearers to operate underneath. The hydraulic roof support generally accounts for over 50 of the total value of a coal mining and excavating system.
The mining efficiency of thin coal seam and very thin coal seam can be improved and the mining cost can be reduced. Results Thin coal seam shear mining combines mining, conveying, and supporting processes together and has the advantages of a low fuselage, no extra support required for the working face, and feasibility in a small underground space.

A hydraulic shovel is typically used in strip mining. A hydraulic shovel is a piece of heavy equipment that can be either tire- or track-driven. The typical hydraulic shovel is a track-driven machine that is used to dig coal and other minerals from the ground and load it into huge trucks to be driven to a mill.
A new hydraulic drawing system of coal mining machine is proposed in this paper. The variable plunger pump adopted in the hydraulic drawing system of coal mining machine is replaced by load-sensing variable displacement pump. The working principle and energy-saving of the new system are introduced. The performance of the new system is obtained by the simulation study using AMESim.
Sep 14, 2020 A Batch Of Mining Equipment Of China Coal Group Was Exported To Spain And The Middle East. On the morning of September 14, a batch of mining single hydraulic props and articulated roof beam equipment were loaded in the intelligent equipment manufacturing workshop of China Coal Group, and then they will be exported to Spain and the Middle East.
The borehole hydraulic coal mining system accesses the coal seam through a hole drilled in the overburden. The mining device is lowered through the hole into the coal seam where it fragments the coal with high-pressure water jets. The fragmented coal is pumped to the surface as a slurry by a jet pump located in the center of the mining device.
With the continuous development of science and technology, mechanical work in the coal, the coal mining machinery hydraulic system has been more common, only the construction of a systematic dimension and control hierarchy management, in order to ensure the inspection results accord with the actual requirements of management.
Dec 18, 2018 Hydraulics in mobile mining machinery is unique. Just as any intelligently designed hydraulic circuit must consider efficiency, performance and reliability, so too must the hydraulics within the mining industry.
In hydraulic coal mining the coal bed is broken down either by means of a high-pressure water jet 5 to 10 meganewtons per sq m, which is formed by monitors, or by means of mechanohydraulic machines mechanical breakdown of the coal with subsequent washing out by the water. The water is supplied to a stope through pipes from centrifugal pumps.
