Abstract
The invention discloses a liquid-phase plasma rock blasting method suitable for blasting rocks and concrete structures. According to the method, strong discharging is implemented in strong sodium chloride or potassium chloride electrolyte solutions for stimulating generation of high-density liquid-phase plasmas; in the high-density liquid-phase plasmas, due to the mutual effect of the electrical property of ion clusters, intense vibration occurs in the sections where ions exist in an instant, high temperature and high pressure are generated in the plasma sections, clustering shock waves of the ions are formed and extend outwards, and therefore the energy of ion waves is spread to the surrounding rocks, natural defects such as joints and fractures in the rocks or the concrete structures are enlarged, new cracks and weakness planes are formed until the rocks or the concrete structures are damaged, and the purpose of blasting the rocks or the concrete structures through the plasmas is realized. Compared with traditional explosive blasting methods, the liquid-phase plasma rock blasting method has the remarkable advantages that dust is avoided, fume is avoided, poisonous and harmful gas is avoided, throwing is avoided, and the noise is low.
Description
Technical field
The present invention relates to Liquid Plasma Rock Blasting method, be particularly useful for general outdoor Geotechnical Engineering Blasting, be also applicable to the demolition blasting of xoncrete structure.
Background technology
Traditional rock or the blasting process of xoncrete structure are the processes that explosive charge can be converted into catalase energy.In traditional bursting work process, except the explosion and crushing object realizing predetermined rock or xoncrete structure, often produce other ill-effect, blast as explosive may discharge a large amount of toxic and harmfuls, can invariably not produce blasting vibration, Property of Blasting Noise, air-shock wave, explosion airborne dust, and exceed the sillar of designing requirement or the throwing etc. of broken concrete, on the one hand adverse effect is caused to burst region and surrounding enviroment, jeopardize operating area and perimeter security simultaneously.The uncontrollability that its basic reason releases energy after being explosive charge.
Therefore, in urban area or densely populated, and in the blasting engineering in circumstance complication region, the ill-effect of strict controlled blasting seems particularly urgent and important, this also become seek new alternative explosive the energy to realize the safety blasting of rock or xoncrete structure, the real motive source of green explosion.
The proposition of Liquid Plasma Rock Blasting method is undoubtedly for urban environment complex area, populated area rock and the safety blasting of xoncrete structure, the realization of green explosion provide possibility.
Summary of the invention
Technical problem: the object of the invention is to overcome the deficiency in conventional explosives shot rock or xoncrete structure, there is provided a kind of completely newly, safety, green rock or the xoncrete structure explosion energy-liquid phase plasma, while realizing the explosion and crushing target of rock or xoncrete structure, make provide blast blasting energy size controlled, and greatly reduce, even stopped the ill-effect of conventional blast.
Technical scheme: Liquid Plasma Rock Blasting method of the present invention, comprises the steps:
1) actual prospecting is carried out to rock mass or xoncrete structure for implementing explosion, position, plasma blasting hole hole is laid in rock mass or xoncrete structure, and carry out bore operation, require that big gun hole will vertically downward, to guarantee that the electrolytic liquid poured into subsequently can not flow out voluntarily;
2) in Plastic Drum, configure sodium chloride electrolysis matter solution, concentration is 0.1mol.L
-1, and add copper sulphate according to the ratio of sodium chloride solution weight 0.05% ~ 1%, fully stir, form strong electrolytic solution;
3) charged to capacitor by charging equipment, and make the crest voltage of capacitor be not less than design load, change depending on blasting medium intensity difference;
4), after the construction of big gun hole, measure its degree of depth and clean out landwaste wherein, after meeting the requirements, reexamining around blasthole hole wall whether there is visible crack;
If there is visible crack, then places in big gun hole and blasthole diameter, polybag that the degree of depth is suitable, then the strong electrolytic solution prepared is poured in the polybag in big gun hole;
If crag is without obvious visible crack around big gun hole, then directly to be poured into by strong electrolytic solution in big gun hole, liquid level is close to big gun aperture;
5) sparking electrode connecting the coaxial cable of Capacitor banks is inserted in the strong electrolytic solution in big gun hole;
6) discharge switch of capacitor is opened, capacitor discharge, high density liquid phase plasma is produced under the electric energy effect that strong electrolytic solution sends at sparking electrode, and form HTHP ion cluster shock wave instantaneously in electric discharge, broken big gun hole perisporium rock, completes a Liquid Plasma Rock Blasting operation.
Beneficial effect: the present invention one utilizes the method for strong electric discharge in strong electrolytic solution to excite generation high-density plasma; Two is utilize interaction electrical between plasma colony, the interval characteristic producing HTHP plasma stock wave is there is at " ion ", fragmentation is carried out to " ion " domain of the existence surrounding rock or xoncrete structure, reaches object and effect that explosive blasting breaks rock.Compared with the rock blasting utilizing commercial explosive to carry out with tradition or xoncrete structure explosion, tool has the following advantages:
1) according to by the intensity of quick-fried body and design feature, the charging voltage of capacitor can be adjusted, to obtain the plasma of respective strengths grade;
2) raw material sources that generation high-density plasma is used is extensive, low price, uses rear environmentally safe;
3) large value capacitor used, coaxial cable and sparking electrode are reusable;
4) liquid phase plasma explosion can have the complex condition of strict demand to use to Property of Blasting Noise, blasting vibration, blasting dust etc.;
5) dust is not produced, without toxic and harmful in liquid phase plasma rock or xoncrete structure blasting process, do not have blasting fume, Property of Blasting Noise is extremely low, and the medium after fragmentation does not almost have throwing, be beneficial to the transhipment of ore after explosion, be more conducive to the prevention and control of shotfiring safety.A kind of green rock-blasting method can be referred to as.
