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
