One of the notable advantages of submarine hammer drilling is its efficiency in penetrating tough materials. Traditional drilling methods may struggle with hard rock formations, often resulting in slower progress and increased operational costs. Hammer drilling wears less on the drill bit, ultimately reducing the frequency of replacements and downtime.

(2) Before starting the drilling rig, check whether the charging pressure of the accumulator is normal; Check whether the scouring water pressure and the lubricating air pressure can be; Check whether there is sufficient lubricating oil in the lubricator, and whether the oil supply is appropriate; Check the reverse tendency of the oil pump motor.

While downhole drilling equipment is engineered to withstand extreme conditions, safety remains a paramount concern in the industry. Proper training for personnel operating this equipment is essential to mitigate risks associated with equipment failure and human error. Regular maintenance and inspection of downhole tools are also vital to ensure reliability and operational safety.

The DTH hammer operates through a system of compressed air. High-pressure air is directed down the drill string, powering the hammer at the end of the drill bit. The hammer strikes the bit with considerable force, fracturing the rock immediately beneath it. As the bit penetrates further, the broken rock is then cleared from the hole by the same air stream, allowing for continuous drilling without the interruptions often associated with other drilling methods.

Conclusion

The submersible drilling rig, available in both internal combustion and electric models, is a device for drilling holes in rocks. The characteristics of drill drilling is outstanding, according to different characteristics can be divided into many varieties, different varieties of drill drilling scope is not the same, facing the classification of drill drilling, the way is briefly introduced as follows:

The following matters should be paid attention to during the use of the drilling rig, and the correct use can bring greater benefits

The roller drill uses the rolling action of the roller bit to break the rock and is suitable for drilling holes of 150 ~ 440 mm in diameter on the hard rock. It has the advantages of high efficiency and low labor intensity, and is widely used in large and medium-sized open-pit metal mines. The drill consists of an impactor (or drill bit), a rotary mechanism, a lifting mechanism, a pressure device, a walking mechanism, a slag discharge system, a drill frame and a drill pipe. Rotary drilling machines are only suitable for drilling softer minerals and coal.
