Description

Full-section rapid drilling rig used for blasting of large empty holes and straight holes in roadways

technical field

The invention relates to a blasting drilling rig, in particular to a blasting drilling rig for coal mine roadway excavation.

Background technique

The drill and blast method is still the main method of coal mine roadway excavation construction for a long time. In the coal mine roadway engineering, the roadways with medium and small sections of 8-23m ² are the main ones. In excavation construction, medium and deep hole blasting of 2-3 meters is the main method, and the key to medium and deep hole blasting is the choice of cutting method. According to the research, the best cutting method for medium and deep hole blasting is straight hole cutting. When cutting straight holes, it is necessary to leave dense holes without charge to improve the blasting free surface. With the research progress of researchers on void effect and rock crushing mechanism, a new method of large void hole straight hole cutting blasting has appeared in recent years, which has become the main technical way to increase the circular footage of medium and small cross-section roadways. The so-called large hole straight hole cutout is to arrange 1-3 straight hole holes with a diameter of more than 100mm without charge in the middle of the roadway section. The charging hole forms two free surfaces to create conditions. It has the advantages of less drilling, less charge and high blasting efficiency. Since the current drilling rig is designed according to the small-diameter drilling with a diameter of 32mm, when drilling a large-diameter hole above 100mm, it is necessary to use a down-the-hole drilling rig for separate drilling, and the operation cannot be carried out at the same time, which affects Drilling construction speed, and it is very troublesome to use two kinds of drilling trucks or drilling rigs back and forth. Since there is no special drilling rig that can drill both large and small holes at the same time, there are not many practical applications for large-diameter hollow holes and straight holes at home and abroad. advantages are not exploited.

At present, most down-the-hole drilling rigs use pneumatic impactors, which are also called pneumatic impactors or pneumatic down-the-hole hammers. The pneumatic impactor is directly connected with the cemented carbide column tooth drill bit to break the rock by impact, using compressed air as the power medium, and using the energy of compressed air to generate continuous impact load. So far there are no examples of pneumatic impactors being used in drill trucks.
