In open-pit mining, the borehole diameter is 50 mm-180 mm and the hole depth is less than 40 meters. It is necessary to change the borehole position frequently. We have developed a series of drills of types of drilling machine in mining for different aperture depths.
Driving modes are hammer type and DTH type. The diameter of hammer type drilling holes is below 120 mm, and the depth of drilling holes is within 20 meters. Driven by hydraulic rock drill. The down-the-hole mining mechanical drilling rig
needs the air compressor to cooperate with it and relies on the impactor to work, so it has better adaptability. The borehole diameter can be large and the depth can be deeper.
For large mining sites. We have a cone drill which can greatly improve work efficiency and drill large boreholes. However, due to its large size, it is impossible to carry out work in a narrow space.
In order to meet the requirements of environmental protection, we have developed different types of drilling machine in mining
with dust collecting device, which can ensure that there is no dust spread during drilling process of mining drilling equipment.
