Broken dish limestone-nepheline mine；South Korea, Japan are studied in terms of plasma detritus rock crack propagation fracture；The country exists
Plasma Engineering application aspect is studied, have passed through research work in nearly more than 20 years, Southwest Jiaotong University, Chinese Mining Industry is big
It learns in (Xuzhou), Chinese Academy of Sciences electrician waits these research institutions to be studied in the application of plasma in engineering.
Currently, relying primarily on breakdown air in terms of catalase generates plasma and in liquid dielectric according to liquid electricity
Effect generates two methods of plasma.Electrode breakdown air generation action of plasma energy release is relatively low, to rock
Lithotrity effect is poor, and discharge process noise is bigger.Do not have using the energy release rate that electrode breakdown air generates plasma
It is more concentrated relative to energy when using liquid as dielectric, therefore at present in terms of catalase mainly using electrohydraulic effect etc.
Gas ions detritus.And the dielectric that electrohydraulic effect plasma detritus process uses is liquid, and there are bigger to ask for liquid
Topic is that liquid portion can be leakage along the hole of rock interior, and this reduces the desired effects used, reduce
The utilization rate of energy increases the cost used.

The component needed.
It is provided by the utility model to use foam solution as dielectric plasma detritus system, it can be matched according to difference
The foam of ratio, different foam bubbles effects are achieving the purpose that promote detritus during discharge.Common plasma is broken
Bubble is not achieved mainly according to the dielectric of inflow water or strong electrolyte as electrohydraulic effect between discharge electrode in technique for rock
Effect of the foam two-phase mixture as dielectric, promotion detritus.It can satisfy engineering reality by a series of controllable air bubble devices of design
The foam quality of border demand, structure is simple, easy to operate to be illustrated.After in the foam injection hole prepared, so that it may be put into
Plasma electrode carries out discharge operation.Apply high-voltage pulse power source post plasma electrode discharge on plasma electrode
Place's release high pressure, high current, and then puncture the intracorporal liquid of foam two-phase and gas, excite inner air and liquid generate etc. from
Daughter, the highdensity plasma of high temperature and pressure act on enormous impact force, effect of the foam in powerful electromagnetic force to rock mass
Under, the foam crumbled and fall of a part generates impact force of crumbling and fall and increases impact force to rock, the foam that a part does not crumble and fall
Bubble generates certain pulsatile impact power internal, further increases the rock in plasma electrode discharge process in relative closure
The surge that churn drill hole generates, wherein the impact force action generated is answered in belonging to drawing on rock for fragmented rock
Power, and the tensile stress of rock is exactly that intensity is relatively low, is easy at lower powers to be crushed rock, reduces broken rock
Difficulty of construction and energy consumption cost improve the service efficiency of energy to a certain extent.
The rock that relatively large volume is encountered when construction, may carry out the process of multiple discharge detritus, this process is just
The crackle of rock occurrence of large-area can be made to generate, while promoting its original crackle, if with other liquid such as water, strong electrolyte
Dielectric, can make the loss of dielectric occurrence of large-area, such plasma electrode be merely able to occur in rock-boring or

Faced when construction need fragmented rock be at drilling orifice of various shapes with when plasma bit contact can exist contact
Not tight, there are crack phenomenons, and the gas for the plasma, high temperature and pressure that electric discharge generates in hole can be made to escape from gap in this way
Out, the rapid decaying for making discharge process energy, reduces the release rate of energy.Use foam two-phase mixture as plasma technique
Dielectric detritus method in discharge process, can block hole existing for rock interior, to a certain degree to a certain extent
The dielectric of quality required for upper holding, volume is unlikely to cause to be lost as liquid electricity dielectric, reduces the utilization of energy
Rate is not easy to practical control, increases use cost.
In view of solution during discharge is influenced by electronics, therefore it is different to have matched in utility model two kinds of bands
Electrical foam dielectric solution.1) anionic electrodeposition medium solution: 0.4% lauryl sodium sulfate；0.4% carboxymethyl cellulose
Element；1.5% polyacrylamide；2) cation electrodeposition medium solution: 0.4% cetyl trimethylammonium bromide；0.2% guar gum；
0.2% Sodium Polyacrylate；Above two dielectric solution component is simple, cheap, and proportion is easy to operate, has preferable bubble
Foam stability.
In addition cationic polymer electrolyte solution may also is that 1.2% cetyl trimethylammonium bromide, 0.1% guar gum, under
Face is that the foam of the foam of such cationic polymer electrolyte solution preparation stablizes time result:
In experiment three, when preparing foam, 0.5g guar gum is added in whipping process, foam volume is
500ml, but be precipitated 50ml liquid all time and extend to 85min.
The time is measured according to experiment it can be concluded that a certain amount of guar gum, which is added, can increase the stability of foam, while
The concentration for increasing cetyl ammonium bromide in a certain range can also increase the stability of foam, in addition prepare foam stirring
A certain amount of guar gum is added in the process, can also increase the stability of foam.
It is full on action time using the foam two-phase mixture with cation in the present embodiment in plasma Rock Technology
Foot electric discharge requires, and the technology time stable to foam does not have strict requirements, and cation foam proportion is simple, solution
It can not be polluted after use by environment degradable, temperature influences smaller, working environment practicability to the cation foam solution
By force, use cost is relatively low, and stability is higher.
