Hydraulic rock drill has only been on the market for over 20 years, but it has played an important role in man’s struggle to conquer nature. In the 21st century, the need for rock drilling engineering and the advances of hydraulic rock drill makes it has a bright development prospect.

1. Hydraulic rock drill is still the key equipment of rock crushing engineering

In the development and construction of nature, humans have explored various rock breaking methods, but so far, the most practical and effective methods are mechanical rock breaking and drilling and blasting.

The mechanical rock breaking method for tunnels and roadways is also called tunnel boring machine method (TBM method). 30%-40% of tunnels in foreign countries are constructed by TBM method each year, and the total length of mechanically excavated tunnels exceeds 3000km. TBM method has played a high-speed, efficient and safe role in the construction of long and large tunnels.

However, TBM method only has obvious effects when used in tunnels above 2000m, so most tunnels are still constructed by drilling and blasting. The experience of hydraulic rock drill in tunnel drilling and blasting method construction has proved that it is the key equipment to increase construction speed and construction conditions, and will continue to play important role in tunnel construction in the future.

2. Hydraulic rock drill has a bright future in non-blast hole construction

The successful application and development of hydraulic rock drill has improved the level of rock hole construction such as anchor bolt holes, grouting holes, and pipeline installation. Since hydraulic rock drill was put into use, various manufacturers have introduced full hydraulic rock bolt machines, which greatly improved mechanized level of rock bolt support.

In the 21st century, with the further development of anchor bolt support technology, the requirements for anchor bolt support mechanization are getting higher and higher. Hydraulic rock drill improves anchor bolt construction efficiency, guarantees the construction quality, and improves construction conditions, making full hydraulic bolt machine have a broader prospect.

Hydraulic rock drill has excellent performance and is easily matched with a variety of hydraulic equipment, which creates more opportunities for various non-blast hole construction. In recent years, hydraulic rock drill has been successfully applied in piercing operations of blast furnace tap in metallurgical industry in China, which has brought high efficiency, economic and safe effect to steel companies. It shows that hydraulic rock drill prospects in non-blast hole construction are unimaginable.
