　　Characteristics of DW16-400/110X single hydraulic prop

　　1. Large work schedule and low cost of safety management:

　　Each specification can replace 2-4 specifications of traditional piston type single support columns, reducing the frequency of changing different types of single support columns due to changes in working face height and roadway roof and floor displacement, and reducing labor intensity for workers and additional backup quantities of support columns.

　　2. High support strength, good safety and stability:

　　The pillar does not have load-bearing welds, and at the same time, the pillar adopts the principle of suspension technology. The suspension force generated by high-pressure liquid directly acts on the top cover end, reaching four fifths of the working resistance. The force on the pillar is only one-fifth, greatly improving the stability and unbalanced load capacity of the pillar support.

　　3. Leakage occurs, with high safety and reliability:

　　Due to structural improvements, the situation of pillar collapse and detachment caused by internal leakage has been avoided. Once a pillar leaks, it can be directly detected with the naked eye on site underground and can be replaced at any time; By adopting the principles of sealing compensation and sealing tightening technology, the greater the pressure on the top plate, the tighter the sealing surface fit, and the less likely it is to leak.

　　4. Long service life, easy operation and maintenance:

　　The overall structure is simple and has a long service life; Easy to operate and maintain, it can greatly reduce the rate of pillar lifting and maintenance.

　　Application scope of DW16-400/110X single hydraulic prop

　　DW16-400/110X single hydraulic prop is applicable to the inclined coal seam mining face where the coal seam dip angle is less than 25 ° -35 °. The applicable conditions of the roof and floor of the coal seam are: the backwardness of the roof does not affect the recovery of the prop, the floor should not be too soft, and the depth of the prop pressed into the floor does not deteriorate the integrity of the floor, otherwise the base should be increased. When used in blasting mining faces with relatively soft coal quality, protective measures should be taken on the surface of the active column coating to prevent collapse. When the pillar is used in conjunction with the wooden top beam or as a point column, the top cover should be replaced with a column cap to avoid damaging the wooden beam.

　　The combination of DW16-400/110X single hydraulic support and metal articulated roof beam column can be applied to any coal mining face with a coal seam inclination angle below 35 °.
