Introduction
Hydraulic support is an important device to ensure safety in coal mines, our country since the 1970s started to introduce and develop hydraulic support, send
Show mechanized coal mining technology, after 30 years of development, it formed an independent hydraulic support technology system. Unlike hydraulic support
Machinery and equipment, which is an essential condition of surrounding rock and coal seams run successfully adapt to mine equipment, according to different seam conditions
Mine conditions and use different frame type and parameters. In order to regulate the development of support construction, according to the hydraulic support technology development status and trends, taking into account the line
Industry custom, standard proposed support construction and classification parameters series, predetermined bracket model designation.
Hydraulic support type, parameters and model designation
1 Scope
This standard specifies the type, model parameters and the preparation of coal mine hydraulic support (hereinafter referred to as the holder) a.
This standard applies to all kinds of support coal mining face in use (not including Simple Stand).
2 support construction classifications and definitions
2.1 According to the structure and relationship between the frame and rock type classification
2.1.1 shield support
2.1.1.1 branched cover shield support
There are four bar linkage mechanism stable, two columns supporting the cover beam, short beam roof beams with hinged cover, balanced jack. Bottom plug into
(Insert lower base scraper conveyor chute) support and do not plug the bottom bracket categories (see Figure 1, Figure 2).

2.1.1.2 Prop shield support
There are four bar linkage mechanism stable, two columns supporting the roof beams, jack balance beam and disposed between the top cover of the beam shield support (see
Fig. 3).
