rock drilling rig

Based on the current main excavation methods of tunnel construction, based on the comparative analysis of rock drilling rigs and traditional technology, the advantages and disadvantages of rock drilling rigs are analyzed, and the feasibility and economy of rock drilling rigs in tunnel excavation are

The tunnel was excavated using a fully computerized rock drilling rig. During the construction process, a series of solutions were adopted based on the geological conditions of the tunnel engineering and the mechanical performance of the fully computerized drilling rig, to continuously optimize the

Drill boom is the positioning and support of drilling, and its performance directly affects the efficiency and quality of drilling. Once the boom stops working, the entire drilling operation cannot be completed. The failure of the drill boom is analyzed and the troubleshooting method is introduced.

Aiming at the problem that the parameters of the rock drilling rig in open-pit coal mines are only displayed on a single machine, and it hasn′ t the function of remote monitoring and real -time viewing, which lead to the problem of low quality of construction holes, a remote monitoring system for

In order to improve the roadway excavation speed and forming quality, and ensure that the roadway section after blasting is flat and smooth, according to the field construction conditions of the test roadway in Lilou Iron Mine, the blasting parameters such as the distance between the smooth

This paper mainly describes the hydraulic working system of the SIMBA H1354 center hole trolley, including the selection of key components, such as pumps, valves, etc., and the debugging of related parameters, which has important reference significance for the operation principle, fault judgment

With the development of mechanical equipment technology and intelligence, more and more intelligent computer technologies have been widely promoted and applied in construction machinery. At the same time of high efficiency, the quality of construction work is improved, the staffing of construction

The original mining equipment in our mine is relatively backward, the workers are labor-intensive, the driving efficiency is low, and the safety cannot be well guaranteed. For this reason, high-efficiency trackless mining equipment such as new hydraulic rock drilling rigs has been introduced

With the continuous deepening of the concept of green development, the traditional tunnel construction technology has been unable to meet the needs of environmental protection and green construction. In this regard, the tunnel construction technology that adapts to the green development concept

The flipping device is the standard configuration of most rock drilling rigs to realize the turning action. In view of the unclear principle of the flipping device and the irregular disassembly and assembly of the repair personnel, this paper describes in detail, in order to provide help for

The rock drilling rig is a special machine used for drilling holes and installing anchor rods in the drillingblasting operations. With the thriving demands for the rock drilling rigs in the domestic markets, the development of rock drilling rigs has seen fierce competitions. The axles

In the process of tunnel drilling and blasting excavation, the optimization of the tunnel construction process and the precision control of the multi-arm rock drilling rig have an important impact on the construction quality and the progress of the construction period. This paper takes

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
