XZQ229 down-the-hole drilling rig down-the-hole drilling rig
Expert evaluation:
The down-the-hole drilling rig is a medium-sized integrated
down-the-hole drilling rig developed mainly for various types of
mines such as quarries, cement mines, and open-pit coal mines. It
can complete the drilling construction of main blast holes and
pre-split holes. Down-the-hole drilling rigs have the
characteristics of large drilling diameter, high drilling
efficiency, and wide adaptability. They are widely used in the
production of mining materials, coal, metallurgy, chemical
industry, etc., and are also used in engineering departments such
as geology, construction, hydropower, transportation, and military.
