Zhongxiang Mining Support Factory was established 3 years ago and is now affiliated to Zhongxiang Group. It is a long-established enterprise that has been specializing in the production and sales of coal support products for nearly 20 years. It is a leading entity with a high reputation in the mining support product industry. It is a company that takes coal system safety first as its sacred mission and is highly professional. The support expert is an enterprise whose core personnel are composed of professionals who have been engaged in this industry for many years from the former Supply Bureau of the Ministry of Coal.
Company Strength
After nearly twenty years of hard work and development, Zhongxiang Mining Support Factory has developed from a simple factory building and one piece of equipment to dozens of large-scale machinery and equipment covering an area of more than 10,000 square meters. A production enterprise with modern standard factory buildings. We have senior engineers, technicians and technicians who independently produce and process various specifications and models of mining steel brackets, miner steel brackets and bracket accessories such as cable clamps, anchor rods, pallets and other mining products. The production and processing scale is strong and can produce steel brackets on a daily basis.
Profiled steel bracket
The profiled steel bracket has significant features such as effectively reducing the occurrence of roof collapse, collapse and other accidents, being safe and reliable, and improving the stability of the mine ventilation system. The use of steel retractable brackets better solves the problem of excavation support.
Characteristics of profiled steel brackets
The profiled steel bracket has significant features such as effectively reducing the occurrence of roof collapse, collapse and other accidents, being safe and reliable, and improving the stability of the mine ventilation system. The use of steel retractable brackets better solves the problem of excavation support. It is widely used in mine tunnels, secondary support of mine tunnels, and support support of mountain tunnels. The profile steel bracket is deeply loved by the mining machinery industry because it can withstand high pressure, has a long support time, is easy to install and is not easy to deform.
Advantages of profiled steel supports
Compared with other rigid supports, profiled steel supports have retractability and stable and reliable load-bearing capacity. They can adapt to the load and deformation of soft surrounding rock. They have high cross-section utilization, convenient support and return, and small maintenance. , the bracket has a high recycling and reuse rate, reduces the use of pit wood, and the environmental protection benefits are very obvious.
Purpose of profiled steel brackets
Profiled steel brackets can withstand high pressure, support for a long time, and are easy to install and not easily deformed.
Compared with other rigid supports, the steel bracket has retractability and stable and reliable bearing capacity, and can adapt to the load and deformation of soft surrounding rock.
The cross-section utilization rate of the steel bracket is high, the bracket is easy to support and return, and the maintenance amount is small.
The bracket has a high recycling and reuse rate, reducing the use of pit wood, and the environmental benefits are very obvious. This project is safe and reliable, effectively reduces the occurrence of roof collapse, collapse and other accidents, and improves the stability of the mine ventilation system.
The promotion and application research of this project has improved the safe production conditions of mines, reduced production costs, is in line with the national policy of replacing wood with steel, and has good environmental and social economic benefits.
Performance characteristics of steel brackets
Top beam.
The top beam is in the shape of a circular arc, and its number can be divided into sections or multiple sections depending on the size of the tunnel section, the stress on the bracket, and the transportation conditions.
.Column legs.
There are three forms of column legs. One is that the upper part is arc-shaped and the lower part is a straight segment. The second is that they are all curved and have only one radius of curvature. The third is that they are all curved but have two a radius of curvature. A base is welded under the column legs, and the size of the base depends on the softness and hardness of the bottom plate
3. Connectors.
The connector is a clamping device between the bracket sections. It can connect the sections. It can also compress the joint part of the two connected steel sections to provide pre-tightening force so that there is friction between the sections. , thereby ensuring that the arched bracket has a certain working resistance and a certain amount of shrinkage.
.Tie rod between racks.
The function of the inter-frame tie rod is to enhance the overall relative stability of the bracket and connect the brackets longitudinally to form a whole.
.Backing material.
The backing material is the filling material between the steel bracket and the surrounding rock. The purpose is to make the steel bracket and the surrounding rock in close contact, improve the stress condition of the bracket, increase its load-bearing capacity and maintain the stability of the surrounding rock. The profiled steel supports must be reasonably calculated during design and should also be used reasonably to ensure safe production in mines and improve economic benefits.
