Briefly introduce that in the construction of the Dapo Tunnel of the Guizhou-Zhangzhou-Changzhou Railway, the three-arm rock drilling rig is used as the carrier, and the principle of controlled blasting is applied. The drill and blast design has been implemented in terms of high-precision initiation

As one of the important machinery and equipment for tunneling mechanization, the fully computerized three-arm jumbo drill has been widely used in tunnel construction. This paper takes the mechanized construction of a high-speed railway tunnel as an example, and describes the construction

Simba_H1354 rock drilling rig is a medium and deep hole rock drilling equipment imported from abroad by Anhui Development Mining Co., Ltd., as the service life increases, due to the failure of the hydraulic working system, there are problems such as low drilling efficiency and high cost of

At present, most of the full-section drilling and grouting equipment adopts the pneumatic down-the-hole hammer single-arm multi-functional drilling rig, which has high cost, low efficiency, slow speed and large pollution. The three-arm rock drilling rig has a large operating range, flexibility

In recent years, large-scale highway construction and development has become the main melody of the transportation sector, under this trend, the traditional tunnel construction technology can not meet the national environmental protection, low energy consumption, economy and high safety and quality

With the increasing progress of large-scale mechanized construction of long tunnels, how to choose the matching three-arm rock drilling rig for excavation, how to use reasonable and optimized technical solutions to solve technical problems in various specific situations, and achieve the effect of

The drilling process of mining brings a lot of dust pollution. Dust with particles smaller than 10 μm is difficult to settle to the ground after being discharged into the atmosphere, and has a strong adsorption force. Many harmful gases, liquids, and heavy metal elements can be adsorbed on it.

Many industrial raw materials and one-time energy sources are derived from mineral resources. The development and utilization of mineral resources has become a favorable support for domestic economic development. In the process of mining open pit mines, down-the-hole drilling rigs are usually used
