Mine Roof Support (MRS) is an important piece of equipment used to support and reinforce the roof of a mine during underground mining activities such as coal mining. They are designed to ensure the safety of miners during the mining process and prevent accidents caused by roof falls or collapses.
Functions and Roles
Supporting the roof:Steel Mine Supports, through its structural design, effectively supports the roof of the mine and prevents it from collapsing due to stress release or changes in geological conditions.
Ensure safety: Provide a safe working environment for miners and reduce casualties and property losses caused by roof accidents.
Improve mining efficiency:Mine Roof Support helps miners to carry out mining operations continuously and efficiently, thus improving the production efficiency of the mine.
Types and Structures
There are various types of Steel Mine Supports, which can be mainly divided into the following categories according to their working principles and structural characteristics:
Hydraulic support: utilizing hydraulic transmission principle, the support arm of the support can be lifted and moved to adapt to different roof conditions by providing power through hydraulic pump station. This type of support has the advantages of large support force and easy adjustment.
Monolithic pillar: including wood pillar, metal friction pillar and monolithic hydraulic pillar. They are usually used for temporary support or auxiliary support, and are characterized by simple structure and easy handling.
Other types: such as anchor support, anchor cable support, etc. These support methods provide support force through anchor rods or anchor cables fixed in the rock layer of the roof plate, which are suitable for specific geological conditions and mining needs.
