Anchor bolt drill drill drill bolt manufacturers B19 is a widely used mining equipment, accessories, and its role in the construction of the mine is great, one of the most important role is to anchor its supporting role deal with harder rock, anchor drill robustness is also very important, the quality of our gorgeous bolt mining machinery production is guaranteed, not easily broken, can apply them in a hard rock mining. Geotechnical drill bolt body reinforcement rods architecture. By longitudinal tension rod bolt action to overcome the shortcomings of rock and soil compression tensile strength is far below capacity. Ostensibly limits of rock and soil from the original body. Macro point of view is to increase the cohesiveness of rock and soil. From the mechanical point of view is mainly to improve the cohesion C and internal friction angle φ of the rock mass. Which is essentially located geotechnical drill bolt body and rock formation of a new complex. The anchor of this complex is to solve the shortcomings of low tensile strength of the rock mass. Making their own rock and soil bearing capacity greatly enhanced. Bolt is among the most basic part of the mine roadway contemporary underground mining, roadway surrounding rock it bound together, so that the surrounding rock supporting their own, and now not only used for mining bolt, but also for engineering and technology in slope, tunnels, dams and other proactive reinforcement. You can say a lot of the industry will be used to anchor the drill pipe, drill As a result the market demand for such products are constantly increasing our gorgeous bolt drill product is expected to occupy a certain position in the market. 28 32 Wet Dry coal drill coal drill dry coal drill coal drill 32 28 Dry Wet coal drill manufacturers to build dry-wet coal drill coal drill 32 28 Dry My company specializes in the supply of coal drill all kinds of twist drill rod, and other mining drill for drilling the borehole using coal, coal mining is an indispensable tool than ideal. hole diameter 55-110 (mm) Dimensions 1000-2000 (mm ) Features: 1, light weight (45% lighter than the old drill pipe). 2, footage fast, small dust, without leaving a vertical hole drilling cuttings into the hole clear. 3, easy snap beans connection, saving strapping material. 4, the rod fell down and drilling tail separation can be used to extend the service life. 5, through good water when wet work.
