Bolt Fasteners High Tensile Strength Rock Bolt For Mining Roadway Safety

In coal mine roadway, the anchor rock bolt is one of the most important materials in a supporting role, Anyang Bolt Fasteners co., LTD., a new heat treatment process, greatly improving the strength and impact toughness of ordinary steel anchor, to solve the ordinary rock bolt hit problem

On November 3, the 2020 National Science and Technology Award Conference was held in the Great Hall of the People in Beijing. A total of 58 achievements won the second prize of the National Technological Invention Award, including anyang Bolt Fasteners Co., LTD. ‘s coal mine roadway impact resistance prestressed support key technology project. On November 11, the reporter came to the Anyang Longteng heat treatment material Co., LTD., located in the North Meng street of Yindu District.


How does Anchor Rock Bolt of Bolt Fasteners Help Coal Mine Industry
In the process of coal mining, coal mine roadway is the channel between the surface and the ore body, bearing the functions of ventilation, drainage, mining, pedestrian and so on. High strength rock bolt is the key to ensure the safety of coal mining. It is not only the transport channel to ensure the normal mining of coal mine, but also the life channel to maintain the safety of the operation personnel. “In order to ensure the safe operation of underground structure construction in coal mine, the mining side must take safety measures such as retaining and reinforcing the side wall of coal mine roadway, which is known as support technology in the mining field.

With the increase of the depth and intensity of coal mining, the traditional support technology can no longer meet the needs of maintaining the safe operation of the roadway, resulting in metal support damage, roof collapse and other phenomena, posing a threat to the safety of the coal mine. The company’s deputy general manager Fu Guangqing introduced, in order to reduce the maintenance cost of coal mine roadway, improve support technology, Anyang Longteng Heat treatment Materials Co., Ltd. in the national “863” program and the national Natural Science Foundation and other projects funded, coal mine roadway anti-impact prestressed support key technology research.

Anchor Rock Bolt Development in Bolt Fasteners
In coal mine roadway, the anchor rock bolt is one of the most important materials in a supporting role, Anyang Bolt Fasteners co., LTD., a new heat treatment process, greatly improving the strength and impact toughness of ordinary steel anchor, to solve the ordinary rock bolt hit problem of easy break by high strength, and greatly reduces the maintenance cost of roadway. At present, the rock bolt material made by the new technology has been popularized and applied in 18 mining areas in Henan, Shandong, Shanxi and other provinces, which provides technical guarantee for mining deep and complex coal resources.


Reporter walked into the production workshop. Next to the long automated high strength steel rod production line, a special working area is divided at intervals. Different equipment is placed in the working area for heat treatment, machining and so on. At one table, two skilled workers are recording their observations. Go to the end of the production line, in the storage area of rock bolts, rock bolts are stacked orderly after packaging.

It is conceivable that these rock bolts will be used to support the roadway after being transported to various mining areas. Anyang Bolt Fasteners Co., Ltd. by virtue of advanced technology, will make important contributions to the safe operation of coal mine underground structure construction and the healthy development of coal mining industry.

In the workshop of Anyang Bolt Fasteners Co., LTD., automated production lines, industrial robots can be seen everywhere, with these advanced process equipment, without manpower can ensure the efficient production of products.

Attention to technology research and development is anyang Bolt Fasteners Co., LTD. At present, the company has in henan province enterprise technology center construction, high strength steel engineering technology research center, Anyang city, Henan province heat treatment, high strength high performance steel laboratory of new materials research and testing, based on these research institutions, technical personnel to carry out independent research and development activities actively, has applied for more than 10 invention patents, utility model patents. Feng Bo, head of the company, said, “Because of our emphasis on technological innovation and independent research and development,
Anyang Bolt Fasteners Co., Ltd. has achieved one brilliant achievement after another. The second prize of The State Technological Invention Award is a recognition of the efforts made by all our employees. We will take this award as an opportunity to continue to tackle key problems and scale new heights of science and technology through independent research and development to promote high-quality development of the enterprise.”
