Description
Technical field
The invention belongs to technical field of opening a mine, more particularly to mining special diamond drill bit and its operation principle.
Background technology
The broken rock effect of diamond bit is completed by diamond particles.It is to be understood that the broken rock effect of drill bit, just must
Solve the broken rock effect of simple grain diamond.In firm hard formation, simple grain diamond makes rock should in high under the pressure of the drill effect
Under power state（About 4200-5700MPa, some data are thought up to 6300MPa）, make rock that lithology transformation occur, become by brittleness
For plasticity.Simple grain diamond wedging stratum, cuts broken rock, cutting depth is substantially equal to diamond particles under moment of torsion effect
Depth of tooth penetration.This process such as " plowing " thus the referred to as plough shear action of diamond bit.
In the larger rock of some brittleness（Such as sandstone, limestone）, the diamond particles on drill bit are in the pressure of the drill moment of torsion
While effect under, the volume of fractured rock is much larger than the wedging and rotary volume of diamond particles., can only when pressure is little
Minor groove is formed along the direction of motion of diamond, intensified pressure can then make the catalase of minor groove deep and both sides, more than gold
The cross dimensions of hard rock particle.
The rock breaking efficiency of diamond bit, except the extraneous factor with lithology and influence lithology（Such as pressure, temperature, stratum
Fluid properties etc.）Have outside the Pass, the pressure of the drill size is important influence factor.As rock bit, when broken rock, all has top layer for it
Broken, fatigue crushes, three kinds of modes of volumetric fracture.Only when there is diamond particles enough ratio to press wedging formation rock, make
When volumetric fracture occurs for rock, preferable rock breaking efficiency could be obtained.
But existing diamond bit is also there is the length for being not easy to be adjusted drill bit, when mining, is easily sent out
The problem of raw chip removal is difficult and is not easy to carry out replacing maintenance.
Therefore, invention mining special diamond drill bit and its operation principle are very necessary.
