Main features of the mining method in the staged rock drilling stage

For the ore-stabilized deposits, if the ore body is below horizontal and moderately inclined, the house-column method can be used, and the ore body below the steep-sloping medium-thickness can be recovered by the retention method. For the ore body inclined to steeply inclined and medium thickness, the stage mining method of section rock drilling can be adopted, which is characterized by dividing the mining room, the mining column, the first mining room and the rear mining column in the mining unit; The stage is divided into several sections, and the middle and deep holes are used in each section of the roadway; the open empty field formed after the mining is finished is processed simultaneously with the returning of the mining column.

1 Boom Drilling Rig

The 1 boom drilling rig is the main drilling equipment in the underground hard rock mine.
Manipulator drilling rig with high level of automation and computerization is not very attractive to mine.
The mine hopes to use the trolley with compact structure, flexible movement, high reliability, high efficiency and high accuracy.
Small enough to enter the shaft through a small section
Maneuverable and flexible enough to walk in winding and inclined passages
The versatility can be used to drill hole, bolt hole and cut hole in all directions.
In recent years, several major rock drilling equipment manufacturers in the world, in order to meet the requirements of mechanized mining of thin ore bodies, have successively developed a variety of small rock drills with high power, which can be used to complete the rock drilling operations that could only be completed by pneumatic drill, so as to significantly improve the efficiency of rock drilling and reduce ore dilution rate.

Hydraulic drilling jumbo is mainly used for tunneling construction in metal mine and other underground engineering. One drilling boom, advanced hydraulic rock drilling system and anti-jamming mechanism ensure the jumbo rapid drilling speed and high efficiency. This jumbo features of great mobility, short turning radius and strong gradeability, thus can improve working environment and get efficiency, quality development.

Robust universal drilling boom creates ideal face drilling coverage. Automatic parallelism and 360 degree roll-over enable easy, fast and accurate positioning for face drilling, sideway drilling and bolt hole drilling.

The layout of components provides excellent vision for the operator in drilling and travelling.Powerful and well balanced 4-wheel drive chassis allows the rig to move through limited space and tough terrain in the mines.

Duo-circuit service brake and enclosed multi-disc parking/ emergency brake ensure safety in tramming and on ramp slope.
Field proven high frequency hydraulic drifter delivers high performance. Trapezoid shaped percussion piston optimizes shock wave transfer efficiency, enhancing penetration and decrease drilling consumables costs.

Comfortable operator station provides safe working condition. Many automatic features simplified the drilling control and helps the miners to concentrate on fast and accurate drilling.

All service points are easily accessible, which simplifies daily routine maintenance for this 1 boom drilling rig in rock ore quarry and underground tunnel drilling blasting DTH purpose.
