has double motion and single movement two kinds. Double motion and
core tube is internal and external core tube following bit and
drill stem rotation, it in no serious loose or broken strata.
Single movement double core tube internal and external tube has
bearing isolation, pipe outer pipe driven only pick up bit
rotation, and broken rock tube does not rotate, avoid to core
friction, vibration, etc., with mechanical damage, so it in serious
loose fractured formations.these, can be well protected cores.
Use double deck core tube take core, bits need to use wall
thickness of the alloy drill or diamond bits.
Due to the rock drill contact surface area increased and the lip
use double deck core tube than ordinary core tube drilling
efficiency to reduce. In the ledge, coal, in order to guarantee
rock (mineral) heart take rate, rules must be use double deck core
tube coring. More complex double core tube, except to finish single
movement, in addition, aluminum, steel tube placed plastic or
qualitative buckled half close tube, have a better protection of
the core role.
Double core tube card broken cores and seal block within the next
