The Scaling Jumbo is a crucial piece of equipment in underground mining operations. After blasting, the roof and sides of the mine often have broken and unstable loose rocks. These loose rocks pose a serious threat to the safety of on – site workers and the normal operation of equipment, just like the Sword of Damocles hanging overhead. The core mission of the Scaling Jumbo is to quickly and efficiently remove these hidden dangers.
In terms of working principle, modern Scaling Jumbos are usually equipped with flexible mechanical or hydraulic arms, with specialized scaling tools such as crowbars and impact hammers installed at the end of the arms. The operator precisely controls the tools to reach into the cracks or weak points of the loose rocks. By using the powerful thrust of the mechanical arm or the impact force of the impact hammer, the loose rocks are separated from the rock mass and made to fall. Some advanced Scaling Jumbos also have remote – control functions, allowing the operator to complete the scaling work from a safe area far away from the danger zone, greatly enhancing operational safety.
In practical application scenarios, Scaling Jumbos are widely used in various underground mines, whether they are metal mines (such as copper mines, gold mines, lead – zinc mines, etc.) or non – metal mines (such as coal mines, gypsum mines, limestone mines, etc.). During roadway driving, every time blasting is completed, the Scaling Jumbo needs to be deployed in a timely manner to clean the loose rocks on the newly exposed rock surface, creating safe conditions for subsequent support, driving, and other processes. In stope operations, it also plays an important role, ensuring that the stope workers can carry out ore mining in a safe environment. In addition to mines, in the construction of some underground engineering projects, such as underground tunnels, underground parking lots, and underground shopping malls, Scaling Jumbos are also used to remove unstable rocks generated after blasting, ensuring the smooth progress of construction.
There are various types of Scaling Jumbos. In terms of power sources, there are diesel – driven models. They are powerful and can move freely and operate in complex mine environments without external power sources. There are also electric – driven models, which have the advantages of environmental protection and low noise and are suitable for work scenarios with high environmental requirements. From the perspective of control methods, in addition to traditional in – cab control, more and more Scaling Jumbos are now equipped with remote – control systems, further ensuring the safety of operators.
Scaling Jumbos have remarkable effects in enhancing operational safety, improving work efficiency, and reducing labor costs. Compared with traditional manual scaling, it can cover a larger working area in a short time and has higher operation accuracy. At the same time, it reduces the exposure time of workers in dangerous areas, effectively reducing the accident rate and providing a solid guarantee for the safe and efficient development of underground operations.
