Description
Technical field
The present invention relates to mine working engineering apparatus field, in particular to one kind can in tunnel automatic segmentation deslagging with
The coring system and its application method of core is truncated.
Background technique
Coring refers to understand roadway surrounding rock rock mass overall condition in coal mine roadway, carries out rock sampling to roadway surrounding rock
Process.
Currently, coring is completed by corer and drilling machine cooperation in tunnel, traditional corer connects to be connected in borer drill rod
End can use corer continuous sampling, then take out in drilling rod after coring cutting head is cut into stratum.This method is because of it
Corer structure very simple and its operation are single and be widely used, however this method major defect is exactly to work as coring
Pipe gets into after certain depth the coal petrography slag that drilling depths cannot effectively be discharged, and thereby results in and often occurs bit freezing in drilling process
With serious dust phenomenon, therefore worker has to wear strict anti-dust mask layer by layer and serious image working efficiency.
Because of the presence of the above problem, it is devised using the corer of the coal petrography slag in hydrauger hole, however
The existing corer water outlet for having the function is located at its end, although certain coal petrography can be discharged in certain drilling depth
Slag, but still seem unable to do what one wishes in the above coring of long range 5m, bit freezing problem still protrudes, and thereby results in a large amount of brill
Hole is wasted halfway.
It in addition to the preceding, is exactly in hard coal rock layer when corer reaches certain depth there are one critical issue
Afterwards, it is difficult to by the core in deep along its bottom be truncated, therefore often occur corer taking-up after, core is retained in bore inner
Difficult situation, thereby have under the drive of drilling machine repeatedly to swing back and forth up and down in the hope of fractureing core and be taken
Out.This not only serious image working efficiency but also is also greatly reduced the service life of related equipment.
