This large-scale equipment delivery marks another key milestone in the brand’s deep layout of the West African mining market. With years of rich experience in serving international mining, quarrying and infrastructure construction projects, UNIQUEMAC has been committed to delivering high-efficiency, stable and cost-effective drilling solutions for global customers. The shipped ZGYX421TA integrated blasting rigs are tailor-made for medium and large-scale rock drilling operations, widely applicable to open-pit mining, quarry stone exploitation, road construction rock blasting and other engineering projects in Guinea. Batch equipment delivery puts forward high requirements on product specification consistency, production quality control and cross-border delivery coordination, and UNIQUEMAC’s mature production and supply chain system fully guarantees the smooth progress of this order.
The ZGYX421TA integrated blasting drilling rig is a flagship upgraded model independently developed by UNIQUEMAC for complex mining and rock drilling scenarios. It integrates a high-power power system, efficient down-the-hole drilling system and energy-saving air compression system, breaking the operational limitations of traditional split drilling equipment. This model is specially optimized for hard rock geological conditions and high-intensity continuous operation scenarios, and is highly suitable for open-pit mine blasting hole drilling, quarry rock drilling, foundation engineering rock drilling and other projects in Guinea. For mining project purchasers, equipment drilling depth, aperture range, integrated configuration stability and field adaptability are the core selection indicators. The ZGYX421TA rig perfectly balances drilling efficiency, operational stability and energy-saving performance, becoming the preferred equipment for medium-depth blasting hole construction in West African mining projects.
Designed for 21-Meter Drilling Depth
The ZGYX421TA integrated blasting drilling rig features a standard maximum drilling depth of 21 meters, which covers the depth requirements of most conventional open-pit mining and quarry blasting projects in Guinea. This drilling depth is precisely matched with the local mainstream blasting engineering design standards, fully adapting to the shallow and medium-depth rock blasting operations of local mineral resources such as granite, limestone and metal ore. In actual field construction, the 21-meter effective drilling depth can flexibly cooperate with different blasting process schemes. According to on-site rock layer hardness, rock stratum structure and engineering construction standards, the equipment can realize accurate depth control drilling, effectively meet the layered blasting and overall mining construction needs of open-pit mines, and avoid equipment performance redundancy or insufficient power caused by mismatched drilling depth.
Drilling Diameter from 90 mm to 138 mm
This blasting drilling rig supports a flexible drilling diameter range of 90 mm to 138 mm, covering the full aperture demand of conventional mining blasting holes and engineering rock drilling holes. Different drilling diameters correspond to different blasting energy release effects and rock breaking ranges, which can be adjusted according to project design standards, rock hardness and blasting operation schemes. The 90 mm small aperture is suitable for fine blasting and partial rock breaking of fine-grained rock strata, while the 138 mm large aperture adapts to large-scale open-pit mining and bulk rock blasting operations. The equipment is compatible with 3.5 inch standard down-the-hole hammers and matched drill tools, realizing seamless matching of different aperture construction, ensuring drilling forming accuracy and blasting construction effect, and improving the overall construction efficiency of mining projects.
Integrated Configuration for Field Operations
The ZGYX421TA adopts an all-in-one integrated design that integrates a diesel power system, screw air compressor, hydraulic walking system and intelligent control system, eliminating the need for external air supply equipment and auxiliary power equipment. The equipment is equipped with a high-efficiency Yuchai diesel engine with a rated power of 162kW, providing strong and stable power output for high-intensity drilling operations. The built-in high-performance screw air compressor achieves an air displacement of 12 cubic meters per minute and a working pressure of 1.4MPa, which perfectly matches the down-the-hole drilling system and ensures efficient rock breaking and slag discharge. The crawler walking structure has a maximum climbing angle of 30 degrees, with strong off-road performance, adapting to rugged mountain roads and complex terrain environments of Guinea’s mining areas. In addition, the intelligent hydraulic control system realizes automatic drilling and depth positioning, reducing manual operation errors and improving construction safety and efficiency.
The ZGYX421TA integrated blasting drilling rig has standardized and unified core parameters, with stable performance and strong scenario adaptability. The following detailed parameter list helps Guinea mining project purchasers quickly verify equipment matching degree and confirm project applicability, providing intuitive data support for equipment selection and project construction design.

To ensure that the four ZGYX421TA blasting rigs can adapt to the long-distance cross-border transportation and local harsh mining environment in Guinea, UNIQUEMAC has completed a full set of standardized pre-shipment preparation and quality inspection work. All four devices are neatly arranged in the factory warehouse for unified final inspection and packaging. The equipment body is marked with clear model specifications, production batches and anti-corrosion identification, which is convenient for customers to accept and manage on-site. The professional inspection team has comprehensively checked the equipment power system, air compressor operation, hydraulic control system, drilling rotating system and walking performance, eliminating all potential operational faults. After the inspection is qualified, the professional team completes standardized equipment fixing, accessory sorting and packaging reinforcement. All supporting drill rods, drill bits and wearing parts are counted and packaged separately to avoid loss during transportation. The whole shipment process strictly follows international cross-border transportation standards, with professional logistics coordination to ensure stable and safe equipment transportation.
Guinea is rich in mineral resources, with complex and diverse geological conditions, including hard rock strata, mixed soil and rock layers and variable terrain environments. Mining project purchasers need to fully combine local actual working conditions to select and configure drilling equipment. First of all, equipment model selection should be based on project design drilling depth and aperture standards to avoid insufficient construction capacity or performance waste. Secondly, according to local rock layer hardness and geological characteristics, confirm the matching drilling mode and supporting drill tools to ensure efficient rock breaking and stable drilling. It is necessary to verify whether the equipment power configuration and air compressor parameters meet the continuous operation needs of local high-intensity mining. In addition, fully consider the convenience of local spare parts supply and equipment maintenance, and prioritize equipment models with complete after-sales support system. Before purchasing, communicate with suppliers in advance about equipment transportation, on-site installation guidance and operator training services to ensure the equipment can be quickly put into production and create benefits for the project.
