Underground jumbo drilling is a high-precision process used to cut into hard rock to access ore bodies. It involves a special machine called a Jumbo drill or drilling jumbo.
A drilling jumbo consists of one, two or three rock drill carriages, sometimes a platform, which the operator stands on to load the holes with explosives, clear the face of the tunnel or do something else.
This wonderful construction vehicle of engineering plays a crucial role in mining and tunneling and laying the foundation for efficient mining operations (How Does Siton Drilling Jumbo Work in Underground Mines – Jiangxi Siton Machinery Manufacturing Co., Ltd., n.d.).
Its primary purpose is to drill holes into rock surfaces for blasting, rock bolt installation, or other excavation activities.
