Flexible Shield pseudo inclined coal mining method Face angle slow, long face, the face having a gently inclined, inclined seam longwall mining method is simple and the production system tunnel arrangement, a series of low tunneling characteristics, The coal mining method uses the shield bracket to separate the working space from the goaf, which greatly simplifies the management of the complex roof and creates favorable conditions for safe production. The coal in the working face slips and reduces the labor intensity. The pseudo-tilt flexible shield support coal mining method is generally applicable to
coal seams with a
thickness of 2-6 m, a stable reservoir, and a small change in the thickness of the coal seam. The height of the working face section of the coal mining method depends on the dip angle of the coal seam. The variation along the slope and the technical conditions of coal mining are generally about 30m. The coal seams have good storage conditions and can be increased to 40m-60m when the structure is simple. During the mining process, the long support is continuously connected in the return air passage, and the air inlet lane is continuously disassembled. When the working surface is pushed to the vicinity of the upper reaches of the mining area, the eyes are arranged and the brackets are gradually placed into a horizontal position, and then all are recovered. The structure of the shield bracket: the length of the steel beam is 3.0-3.2m. The specification of the steel beam should be selected according to the width of the bracket. The steel wire rope can be used for the old steel rope with a diameter of 20-30mm, and the length of the steel rope is about 20-30m. The number of steel ropes is determined according to the width of the bracket, and 2-3 of the width is less than 3 m, and 5-6 may be used when the width is 3 m or more. 2-3 layers of bamboo rafts are attached to the steel beams. 
Double Deep Reach Truck
Unlike common
reach trucks or forklifts, the double deep reach truck is a narrow-aisle reach truck with deep reach forks to deposit or retrieve
pallets that are set in the rack two deep. Deep-Reach forklift trucks save two
out of five aisles versus single deep storage, allowing double-deep pallet
storage in the racks to extend the storage space.
The double deep reach truck with electric
fork has an EPAS steering system that ensures operation safety even if the motor
has broken. There are other practical designs: OPS (operator sensing system), 8kw
driving motor, electronic proportional control valve, wheel display, floating
drive rear axle structure, electromagnetic brake, etc.
The load capacity of RRE double deep reach
truck is 1.5ton with max lifting height 10160mm. There are many additional
options for you to choose from: fork camera, side shift function, preselector lifting
height function, fork horizon indicating lamp, laser fork position indication,
battery trolley, battery automatic replenishment device, front light, working
light. It is practical and durable because of designs above and high strength
fork as well as big battery with long life. And we believe this kind of forklift
will help you to deal with much difficulties in modern storage era.
