en.Wedoany.com Reported - Recently, China Xinjiang Xuefeng Blasting Engineering Co., Ltd. (referred to as "Xuefeng Blasting Company") successfully deployed the STM-15C intelligent multi-functional belt conveyor stemming truck at the construction site of its No. 2 Mine Project Department for open-pit blasting hole stemming operations. Designed for blast holes with a diameter of 115 mm, the equipment requires only about 15 seconds to stem a single hole, improving efficiency several times over traditional manual stemming methods. This marks the transformation of the project department's blasting operations from manual, extensive practices to mechanized, efficient, and intelligent precision operations.
Founded in 2003 and registered in Urumqi, Xinjiang, Xuefeng Blasting Company is a wholly-owned subsidiary of Xinjiang Xuefeng Technology (Group) Co., Ltd. (stock code: 603227) and holds a Class A blasting operation unit license (commercial). The company is primarily engaged in blasting design and construction, blasting safety assessment and supervision, earthwork engineering, and general contracting of mine engineering construction, providing blasting services for multiple large-scale open-pit mines in Xinjiang.
Traditional open-pit blasting hole stemming has long relied on manual labor, which suffers from high labor intensity, low efficiency, uneven stemming density, and high safety risks due to elevated and edge operations. The newly deployed STM-15C intelligent stemming truck, developed and manufactured by a domestic equipment company, is specifically designed for open-pit mines and large-scale rock blasting projects. It integrates automatic hole seeking, precise positioning, one-key stemming, and remote control. The equipment features a dedicated mining chassis that flexibly adapts to complex mine terrain, dual side and rear telescopic conveyors for full coverage of the operation area, and a hopper equipped with a hydraulic steel screen and vibration discharge device for dual anti-clogging protection to ensure continuous and stable operation. The intelligent control system, combined with visual positioning technology, automatically adjusts the filling volume and stemming speed based on the blast hole diameter, ensuring uniform and consistent stemming quality. Additionally, it supports remote control operation, enabling man-machine separation, effectively reducing on-site personnel, and mitigating safety risks at the source.
The successful application of this intelligent stemming truck represents an important practice by Xuefeng Blasting Company's No. 2 Mine Project Department in advancing the intelligent upgrade of construction operations. The project department stated that it will continue to accumulate operational experience, optimize workflows, and intensify the promotion and application of intelligent equipment, driving safe production, quality improvement, and efficiency enhancement through technological innovation, providing technical support for blasting operations in the construction of modern smart mines.
