Drilling tools for underground mining
2021-09-14
In China's mining resources, underground mine resources account for a large proportion. The mining of underground mine resources should adopt different drilling and blasting mining technology according to the production situation of the mine. Generally, underground mining can be divided into shallow hole drilling (hole depth 6m) according to the depth of the drilled hole,
Light-duty drilling tools for rock drills

Light rock drilling machine refers to a manually operated rock drilling machine. The dead weight of this kind of rock drilling machine is less than 35kg. It uses manual hand-held or air leg support as the working platform. The rock drilling impact and propulsion force are relatively small. Commonly used drilling tool products include H 19mm, H22mm, H25mm hexagonal integral drilling rod, cone connecting drilling rod and 38~42mm sheet-shaped in-line drilling bit, cross drilling bit and four-tooth, five-tooth ball tooth drilling bit, etc.
Current Situation and Market Development of Rock Drilling Tools Industry
2021-07-27
With the rapid development of China's economic construction, the demand for rock drilling tools in mining, energy construction, infrastructure construction and traffic road development and other engineering fields has shown an upward trend, and at the same time, higher requirements have been put forward for the quality, type and performance of drilling tools. Therefore, it is necessary for us to understand the types, use sites and market development trends of drilling tools in order to produce more and better drilling tools, to meet market demand while improving the overall level of China's rock drilling products.

The full hydraulic excavation drilling rig is mainly used for tunnel excavation and underground drilling and blasting construction projects. This series of drilling rigs adopts rubber tire travel mode and diesel engine as the power system of the whole vehicle. According to different construction conditions, different types of drilling arms, propelling arms and different lengths of rock drilling rods are selected for the heading drilling vehicle. At present, the most widely used full hydraulic excavation drilling rigs in the domestic and foreign markets are the Boomer series drilling rigs produced by Atlas Copco.

In the late 1940 s, with the rapid development of pneumatic rock drilling machinery, the efficiency of rock drilling production has been continuously improved. However, in order to improve the output power of rock drilling machinery, it is necessary to increase the diameter of the piston, and the weight of the rock drilling machinery is also increasing. Some rock drilling machinery has been completely manipulated manually.
