Description
Technical field
The present invention relates to rock mass Rock Technology field, more particularly to it is a kind of use foam solution as it is dielectric it is equal from
Sub- detritus method and system.
Background technology
Catalase is mankind's nature remodeling, the main method using natural resources, safe and efficient novel Rock Technology
The numerous areas such as mining, tunnel piercing, drilling well, pressure break, building are can be applied to, there is broad prospect of application.Traditional is quick-fried
Broken technology also needs to the dissipation for waiting for detritus sedimentation and the cloud of dust after explosion, is produced after explosive blasting due to using chemical explosive
Raw flue dust and remaining chemical substance can cause environment prodigious pollution, and the safety problem of explosive storage can also band
Carry out nonproductive administration fee.Compared with traditional blasting technique, plasma Rock Technology is domestic and international emerging one kind
Efficient detritus method is discharged at electrode by high-voltage pulse and generates plasma, and dielectric is boring under high temperature and pressure effect
Rock is crushed in hole.The active force that blasting generates is the longitudinal tension stress to rock, and broken effect is more preferable, broken rock
Process is pollution-free and slungshot, consuming little energy, noise, dangerous low rock.
The country such as South Korea, Russia, U.S. all plasma Rock Technologies have carried out research work, and part etc. from
Daughter detritus equipment has been used in engineering.The space research center of Auburn University of the U.S., single pulse 200kJ, punching
It hits electric current and reaches 200kA, and grasp the novel electrode of independent research and special dielectric technology, it is bigger volume can be blown
Rock, and rock fracture process is without slungshot, dust etc.；The impulse discharge energy 300kJ of Canadian Noranda corporate devices,
After continuous discharge 250 times, processing ore is 3~4 tons；The technology is used for powder by Russian Academy Of Sciences rare earth element research institute
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, the research work that have passed through nearly more than 20 year, Southwest Jiaotong University, Chinese Mining Industry is big
It learns in (Xuzhou), Chinese Academy of Sciences electrician waits application of these research institutions in plasma in engineering to be studied.
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.The energy release rate for generating plasma using electrode breakdown air does not have
It is more concentrated relative to energy when using liquid as dielectric, therefore mainly uses electrohydraulic effect etc. in terms of catalase at present
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.

Specific implementation mode
It is right with reference to the accompanying drawings and detailed description in order to make those skilled in the art be better understood from the present invention program
The present invention is described in further detail.
Embodiment one
With reference to figure 1, use foam solution as dielectric plasma detritus method, this method the present embodiment provides a kind of
Include the following steps：
S3, foam is injected into the drilling bored during detritus
The foam prepared is injected into the drilling bored during detritus；The demand of specific foam can be according to brill
The size and depth in hole etc. determine.
S4, foam is ionized in drilling, the impact force fragmented rock body generated using foam ionization
After the foam prepared is injected in the drilling bored during detritus, so that it may to be put into plasma electrode, into
Row discharge operation.Apply release high pressure at high-voltage pulse power source post plasma electrode discharge, high electricity on plasma electrode
Stream, and then puncture liquid and gas in foam two-phase mixture, excite inner air and liquid to generate plasma, high temperature and pressure is high
The plasma of density acts on enormous impact force to rock mass, and the powerful electromagnetic force under the action of, a part crumbles and fall foam
Foam generates impact force of crumbling and fall and increases impact force to rock, and the foam bubbles that a part does not crumble and fall generate one in inside
Fixed pulsatile impact power further increases the impact that the rock-boring in plasma electrode discharge process in relative closure generates
Pressure, wherein the impact force action generated is for fragmented rock in belonging to tensile stress on rock, and the drawing of rock is answered
Power is exactly that intensity is relatively low, is easy at lower powers to be crushed rock, reduces the difficulty of construction and energy consumption of broken rock
Cost.
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
Part occurs breakdown air and generates plasma and then achieve the effect that detritus, but energy release in this way is relatively low, while engineering
Faced when construction at the drilling orifice for needing fragmented rock to be variously-shaped 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.Using 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, volume required for upper holding is unlikely to cause to be lost in as liquid electricity dielectric, reduces the utilization of energy
Rate is not easy to practical control, increases use cost.
In some embodiments, further include before (i.e. S1) in the drilling bored during foam is injected into detritus with

In experiment three, when preparing foam, 0.5g guar gums are added in whipping process, foam volume is
500ml, but all time lengthenings of 50ml liquid are precipitated to 85min.
Measuring the time according to experiment can show that a certain amount of guar gum, which is added, can increase the stability of foam, while
The stability of foam can also be increased by increasing the concentration of cetyl ammonium bromide in a certain range, 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 of the band cation in the present embodiment in plasma Rock Technology
