In general, in order to increase the efficiency of work in tunnel excavation, urban land development, quarry blasting, underground cavity, subway construction, blasting work is performed to apply strong impact to rock or rock to be crushed.

To do this, first examine the characteristics of the rock to be fractured such as strength, jointing and cracking, and surrounding conditions such as surrounding buildings in detail.Then, based on various data required for the construction, the unit combination, detonation method, and detonation location applicable to the actual construction site Must be determined.

The unit combination may be divided into rock crushing material and the rock crushing material into a sealed material that is placed in the perforated blasting hole and seals it. As shown in FIG. 1, the rock crushing material includes gunpowder (2), thermite (4), reaction rate enhancer (6), electrolytic fluid material (8), and the like, and the sealing material includes a fixing agent (10), A colorant 12;

The explosives (2) are any type of mixed explosives, chemicals, lead-free explosives, dynamite, chemicals, etc., which are usually manufactured and sold for civil use.

The termite agent (4) is a metal oxide copper (I) (Cu₂O), copper (II) (CuO), iron oxide (FeO), ferric trioxide (Fe₂O₃), triiron tetraoxide (Fe₃O 망), manganese dioxide (MnO₂), etc. It is used by mixing one or more selected from alkali metal, alkaline earth metal, aluminum (Al).

The reaction rate enhancer (6) is to induce a net reaction between the reaction units and increase the reaction rate to increase the rock power by inducing a complete reaction in a closed space, silicon dioxide (SiO₂), di aluminum trioxide (Al₂O₃), Low specific gravity and ultra light fine particles such as ferric trioxide (Fe₂O₃) and calcium oxide (CaO) are used as the main component, and aluminum (Al) powder having a high calorific value is mixed and used.

The electrolytic fluid material (8) is to reduce the noise or to prevent the explosion caused by the flame generated during the incomplete reaction is a solution in which the alkali metal or alkaline earth metal halides, oxyacid salts and sodium chloride (NaCl) in water Used.

The fixing agent 10 is for controlling noise and scattering in response to changes in the surrounding environment such as rock cutting, stratification, and groundwater leakage, which may occur in the drilling of the rock, and the construction of clay, cement, fastener, gypsum, etc. After properly formulated according to the water absorption is used.

The colorant 12 is to completely seal the upper part of the fixing agent 10 after the crushing materials are inserted into the perforations, and the upper part of the fixing agent 10 is again made of sand, small gravel, and rock chips. Used to seal once.

Therefore, various unit combinations applicable between the materials are inserted into the blast holes drilled horizontally or vertically on the rock, and the initiator is connected to the wire to break the rock.
