Hydraulic Roof Support Details

The hydraulic roof support is a structure used to control the pressure of the coal mining face. The mining ballast acts on the hydraulic support in the form of external load. In the mechanical system of the interaction between the hydraulic support and the surrounding rock of the mining face, if the combined force of the supports of the hydraulic support and the combined force of the external load acting on the hydraulic support by the roof are exactly the same line, the hydraulic support is very suitable for the surrounding rock of the mining face .

Hydraulic roof support is an important part of fully mechanized mining equipment. It can reliably and effectively support and control the roof of the working face, isolate the goaf, prevent the gangue from entering the working face and push the conveyor. It is used in conjunction with coal mining machines to realize comprehensive mechanization of coal mining, solve the contradiction of roof management lagging behind coal mining in mechanized coal mining, further improve and increase the efficiency of coal mining and transportation equipment, reduce the labor intensity of coal workers, and ensure Safety of coal miners' lives.

Classification of hydraulic supports

There are many types of hydraulic supports. According to the interaction with surrounding rock, they can be divided into three types: support type, shield type and support shield type;

According to the moving method, it can be divided into two types: integral self-moving type and step forward moving type;
According to the place of use, it is divided into two types: working surface support and end support;
According to the thickness of the coal seam and the mining method, it is divided into a networked support and a hydraulic support for the top coal caving.

Performance characteristics of hydraulic supports:

In recent years, the research and development of hydraulic supports in our country has developed rapidly, from basically relying on imports to developing by self-designing and self-manufacturing, with a wide range of varieties, complete functions and reliable quality.

Important performance characteristics:

1. Good vertical and horizontal stability;

2. Strong protection performance;

3. Fast moving frame;

4. Strong adaptability to the top plate.
