The demonstration model mine of the windlass in Shicao Village, Shicao Village, Ningxia Coal Industry of National Energy Group was unveiled

On August 1, in the Shicao Village Coal Mine of Ningxia Coal Industry of National Energy Group, the "Sany Heavy Loading Winner Demonstration Model Mine" was officially unveiled. Lu Fengyuan, director of Shicao Village Coal Mine of Ningxia Coal Industry of National Energy Group, Wei Wei, director of the mechanical and electrical mine, Han Fangjun, chief of the mechanical and electrical section, Ma Chong, deputy director of the main engine management department of Sany Heavy Equipment Marketing Company, Chen Kai, general manager of Xinganning Coal Machinery Branch, and many other leaders attended and witnessed. This milestone marks the fruitful results of the cooperation between the two sides in the field of intelligent tunneling, and sets a new benchmark for safe and efficient tunneling, providing replicable valuable experience for mechanized and intelligent tunneling operations in Ningxia and even the national coal industry.

As an important partner of the intelligent tunneling of the Ningxia Coal Industry of the National Energy Group for a long time, 67 Sany Heavy Equipment Anchor Machines have been stably in service in the Ningxia Coal Industry of the National Energy Group, of which 8 are rooted in the Shicao Village Coal Mine.

Build an industry-level intelligent tunneling system

The demonstration mine systematically verifies the application ability of intelligent tunneling equipment under complex geological conditions, and its biggest breakthrough lies in the construction of a complete technical solution covering process design, equipment collaboration, and safety control, rather than just solving a single scenario problem. For example, in the recent key task of the mine - the 220610 working face large-section rock tunnel excavation, Sany EBZ-260M is usedAnchor and protection integrated machineAs the core carrier:

Large-section construction problems: The tunneling section of the 220610 working face is three-center arch, with a tunneling width of 6m, a tunneling height of 5.1m, and a section of 28 square meters.

Equipment efficiency bottlenecks and high personnel intensity: traditional transportation systems have problems such as slag spilling and leakage, and the need for multiple people to work together. Traditional picks wear out quickly and are replaced frequently, which not only increases costs but also restricts continuous and efficient production.

Collaborative innovation and multiple breakthroughs

In the face of many challenges, Sany reinstalled the integrated excavation and anchor protection machine to accurately solve the pain points:

Intelligent and efficient operation:The trinity of digging anchors and protection, the process is seamlessly connected, and the high-precision cutting and support of the roadway vault is given priority to the safe and efficient completion of the roadway vault, and then the accurate cutting of the roadway and bottoming operation, which effectively overcomes the difficulties of large-section roadway construction.

Intelligent remote control anchor:By "removing the handle", the anchor is set up to realize the remote operation of the remote control to replace the traditional mechanical operation, realize the remote and intelligent anchor setting, and effectively avoid the safety risks of head-on operation.

Efficient Transportation Innovation:The second transport is used to replace the scraper conveyor to lap the electric drum belt, which effectively solves the problem of slag scattering and leakage at the lap point and reduces the labor intensity of the post workers. The chain mode is adopted between the adjacent equipment of the transportation and transfer point, and one person operates multiple equipment, which reduces manpower and improves efficiency.

Rugged design:Sany customized high-strength picks, extended the pick replacement cycle by 2 days, increased the cutting efficiency by 15%, and achieved efficient production.

Three-dimensional dust suppression treatment:Make full use of the high-performance dry dust removal fan system provided by EBZ-260M, with high-efficiency multi-stage spray and water curtain, to build a multi-level dust collection barrier and improve the working environment.
