Liquid-phase plasma rock blasting method

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 [0001] The invention relates to a liquid-phase plasma rock blasting method, which is especially suitable for general open-air geotechnical engineering blasting and also for blasting demolition of concrete structures. Background technique [0002] The blasting process of traditional rock or concrete structures is a process in which explosive explosion energy is converted into rock crushing energy. In the process of traditional blasting operations, in addition to achieving the purpose of blasting and breaking the predetermined rock or concrete structure, other harmful effects will often occur. For example, the explosion of explosives may release a large amount of toxic and harmful gases, which will inevitably produce blasting vibration, blasting, etc. Noise, air shock waves, blasting dust, and throwing of rocks or concrete fragments exceeding the design requirements, etc., on the one hand, have adverse effects on the blasting area and the surrounding environmen...
