If you’ve ever been on a mining site, a quarry, or a large construction project, you’ve probably seen a drilling machine that can handle tough rock with surprising speed. Most of the time, that will be an Integrated Down the Hole Drill Rig. Unlike traditional drilling equipment that requires multiple machines or separate systems, an integrated drill rig combines everything into one unit. The air compressor, hydraulic system, drilling mechanism, and control system all work together, making the entire drilling process smoother and more efficient. How Does an Integrated Down the Hole Drill Rig Work? The working principle is actually easier to understand than many people think. The drill rig uses compressed air to drive a down-the-hole hammer located at the bottom of the drill hole. Instead of creating impact force from the top, the hammer strikes directly where the rock is being drilled. This allows energy to transfer more efficiently, especially when working with hard rock formations. At the same time, the drill bit rotates while the hammer delivers continuous impacts, breaking the rock into small pieces. The compressed air also pushes the rock chips out of the hole, keeping the drilling process clean and reducing the chance of...

Underground drilling rigs are key equipment for underground mining, mainly used for blasting preparation. Workers position the drill arm against the working face to drill planned holes, then place and detonate explosives. Accurate and steady drilling guarantees effective blasting. Underground drilling rigs have many types to adapt to different terrains and spaces. Large rigs with single or double arms are widely used in medium and large mines. Double-arm models work more efficiently in wide areas, while single-arm ones are flexible and ideal for narrow tunnels. Low-height mine tunnels need specially designed low-profile rigs instead of simply shrunk versions. For narrow but high tunnels, narrow-vein drill rigs are preferred for easy movement and drilling work. Most traditional rigs run on diesel. It works steadily and is independent of underground power supply. Meanwhile, battery electric rigs have obvious strengths: no exhaust, lower operating temperature and less noise, which greatly better miners’ working environment. Zhengzhou Kaishan underground drilling rigs focus on operational safety and comfort. Fitted with air-conditioned cabins, anti-vibration systems and easy controls, they ease workers’ tiredness during long shifts while ensuring safety. To pick a proper drilling rig, take tunnel size, rock condition, on-site facilities and safety rules into account. No...

The core difference between Integrated DTH Drilling Rig and Separated DTH Drilling Rig is: the Integrated DTH Drilling Rig integrates the air compressor and drilling mainframe on one chassis as a single unit; the Separated DTH Drilling Rig uses a standalone compressor connected by air hoses. Both Integrated DTH Drilling Rig and Separated DTH Drilling Rig from Zhengzhou Kaishan feature excellent performance. They are different in mobility, fuel consumption, operation, maintenance, and application. If you want to know how to select the right Integrated DTH Drilling Rig or Separated DTH Drilling Rig, please keep reading. 1. Structure and layout The Integrated DTH Drilling Rig adopts an all-in-one structure. Engine, air compressor, hydraulic system, drill boom and undercarriage are integrated together without external air hoses, making the Integrated DTH Drilling Rig more compact. The Separated DTH Drilling Rig includes a drilling mainframe and an independent air compressor connected by hoses. The Separated DTH Drilling Rig is lighter and can be transported separately. 2. Power and energy efficiency The Integrated DTH Drilling Rig is driven by a single engine with low energy loss and low fuel consumption. As a stable rock drill, the Integrated DTH Drilling Rig performs well in continuous working....

An Integrated DTH Drilling Rig is a highly compact, all-in-one drilling machine. This Integrated DTH Drilling Rig combines the power unit, screw air compressor, hydraulic drilling system, and crawler undercarriage into a single mobile unit. Different from traditional split-type DTH Drilling Rig models that rely on external compressors and independent power supplies, the integrated structure of the Integrated DTH Drilling Rig supports fully self-contained operation with no extra external connections required. Core Working Principle DTH drilling relies on a down-the-hole hammer and drill bit placed at the bottom of the borehole to directly impact and break rock. The Integrated DTH Drilling Rig adopts a single-engine configuration, which simultaneously powers the built-in air compressor for the DTH hammer and the hydraulic system that controls the drill boom, rotation and propulsion. This working mode makes the Integrated DTH Drilling Rig deliver stable and efficient drilling performance in various rock conditions. Key Advantages Benefiting from the integrated crawler design, the Integrated DTH Drilling Rig boasts excellent flexibility and strong terrain adaptability. The Integrated DTH Drilling Rig no longer needs to tow separate compressors and auxiliary equipment, which drastically cuts down the time for on-site setup and site transition. Equipped with a unified single-engine...

At the Hubei Yihua Shanshuya Mining site, Kaishan Heavy Industry’s intelligent tunneling drilling rig (underground rock drilling robot) has been in continuous and normal operation for three months. To meet the diverse mining needs of its customers, Kaishan Heavy Industry has customized and upgraded its ADS (Automatic Drilling System). Relying on this system’s superior automatic scanning technology and intelligent algorithms, the underground rock drilling robot can accurately complete the automatic scanning of the working face and tunnel contours, achieving automatic planning and adjustment of drilling paths and parameters. This ensures operational efficiency and accuracy while simplifying manual operation processes and reducing manual labor intensity. The widespread application of Kaishan Heavy Industry’s underground rock drilling robot will further promote the intelligent development of the mining industry. In the future, Kaishan Heavy Industry will continue to be driven by technological innovation, bringing more surprises to the mining sector!

At the Xingfa Group Shukongping Phosphate Mine, 4 Kaishan Heavy Industry intelligent tunneling drills (underground rock drilling robots) have been put into use and have been working normally for 16 consecutive months. With advanced intelligent technology, the automatic hole completion rate of Kaishan Heavy Industry’s rock drilling robots is as high as over 95%, realizing a new mode of unmanned operation on site. Operators only need to be in the monitoring hall to observe and control the operation process of the rock drilling robot in real time, ensuring operation efficiency while avoiding personal injury during the operation. 

Recently, representatives of Phu Bia Mining Co., Ltd. of Australia visited the Phu Bia Mining booth at the Shanghai International Engineering Machinery Exhibition and issued a standard approval certificate to Kaishan Heavy Industry. After a year and a half of inspection, Kaishan Heavy Industry’s tunneling drill vehicle successfully met the Phu Bia Mining standard with its excellent performance. Phu Bia’s recognition of Kaishan Heavy Industry’s equipment is an important milestone for the company to enter the Australian market, marking a solid step for Kaishan Heavy Industry in its internationalization process and demonstrating the company’s technical level in the field of mining equipment. Looking to the future, the cooperation between Kaishan Heavy Industry and Phu Bia Mining will continue to deepen, and jointly promote the continuous innovation and upgrading of mining equipment technology!

On November 30, 2024, another group of central enterprise leaders visited Kaishan Heavy Industry’s intelligent tunneling drilling vehicle (underground rock drilling robot) after visiting the Shanghai International Construction Machinery Exhibition (bauma China). This is another on-site inspection of Kaishan Heavy Industry’s intelligent rock drilling equipment.
