drill jumbo

With the coal mine gradually moving towards deep mining, the increase of rock burst on the roof and floor of the roadway is followed by the increase of tunneling risk and low tunneling efficiency of hard rock roadway, and the existing roadway deformation is increased, roof caving is prominent and

Xunke Gold Mine innovatively adopts Simba1354 jumbos to drill medium⁃long holes in cutting shafts and optimizes the cutting manner, borehole diameter, construction precision, charge structure, and blasting times. Barrel⁃shaped cutting is chosen to offer a free face and compensation room. 120 mm

For development of large equipment，such as drill jumbos，digitalization and intelligence are the trends in future. In order to clarify the research direction of the self-developed drill jumbo，combined with the current status of the drill jumbos applied in China's underground mine，where the drilling

In view of complex assembly of hydraulic rock drills that their cause of troubles and damage are numerous. The text as based on multi home made hydraulic rock drills in operation is going to introduce mainly the rotation types, impact types, water circulating types, air circulating types

In conventional drift excavation，midline and waistline are demarcated manually which is a complex process and prone to errors．At the same time，in the drilling process，the actual location of boreholes often deviates from the designed location，which will result in uneven excavation face

For accelerating the construction speed of Tianxing iron mine and completing the project on time, high efficiency jumbo is planned to be used for mine development. Furthermore, operator can control the jumbo under FOPS canopy which can guarantee the operator safety.
