DTH drilling rigs are mainly used in various projects such as mining, building foundation excavation, water conservancy, power station, building materials, transportation and national defense construction. Compared with common rock drills, it has the characteristics of deep drilling, large drilling diameter, high drilling efficiency, and wide application range. It is currently a large-scale rock drilling equipment for general use.
With the increasing requirements for efficiency and mining automation level, the future down-the-hole drilling rig has great potential in the domestic market. Therefore, it is of great strategic significance to vigorously develop intelligent integrated hydraulic down-the-hole drilling rigs based on their own technical strength.
At the same time, this is also in line with the national "Tenth Five-Year Plan" to support the development of intelligent product technology for the integrated control of mechatronics and hydraulics, and to support the development and application of product energy-saving technologies and advanced environmental protection technologies.
The first is to improve the series of integrated hydraulic down-the-hole drilling rigs. At present, my country's integrated hydraulic down-the-hole drilling rigs include Sunward Intelligent SWD165 series drilling rigs and Changsha Mining Research Institute cS165E series drilling rigs, but they are only suitable for open-pit rock drilling. The underground hydraulic intelligent down-the-hole drilling rig, which is small in size and convenient to move, is affected by various factors and is still at a stage in my country, but the share of underground drilling in China is quite large. Therefore, the market for underground smart DTH drilling rigs is quite large.
The second is to develop an integrated intelligent down-the-hole drilling rig based on the integrated hydraulic down-the-hole drilling rig that has been developed. The intelligence of the cobalt machine can improve the efficiency of rock drilling, and it can also make necessary preparations for the realization of unmanned mining in our country.
It can be seen from the above analysis that the development prospects of our down-the-hole drilling rigs are very good in the future. With the rapid development of the construction industry, the utilization space of down-the-hole drilling rigs is also very large.
