Definitions
- the invention deals with double-layer, three-layer or multi-layer detonation tubes, also referred to as the Shock Tube type, used for industrial nonelectric detonators.
- Shock Tube type used for industrial nonelectric detonators.
- it deals with the design of their body to enable economically acceptable separation of remainders of such detonation tubes of non-electric detonators after the execution of blasting work from the other substances from the processed mined material.
- a detonation tube with the possibility of easy machine separation from broken stone is achieved with the use of a detonation tube with improved separability from processed broken stone designed as double or multi-layer detonation tube of an industrial non-electric detonator containing the active component of the detonator stored in an at least double-layered tubular body or package in accordance with the presented invention
- the principle is that at least one layer of the body or package of this detonation tubes is made of a magnetic material where this magnetic material is beneficially produced as a mixture of the magnetic and non-magnetic main material component while it may be especially advantageous if the content of the magnetic main material component in individual layers of the body or package of the detonation tube is 2 to 60% of weight and the rest to 100% consists of the non-magnetic main material component, all related to the weight of individual layers, or even better, if the content of the magnetic main material component of individual layers of the body or package is 10 to 30% of weight, related to the weight of
- the magnetic main material component may be beneficially produced on the basis of magnetite - Fe 3 ⁇ 4 , or on the basis of ferrite with the general formula Me"Fe 2 ⁇ 4 , where Me represents Co, Mn, Ni, Ca, Cu, Zn, Mg, or ferrite with the general formula Ln ⁇ Fe 2 ⁇ 4 , where Ln represents noble earth elements, or on the basis of noble earth elements in the oxidation degree II, or on the basis of ferric oxide in the modification Y-Fe 2 O 3 , or on the basis of powder iron, or on the basis of a magnetic alloy of iron or on the basis of a mixture or alloy containing the above mentioned magnetic partial components, where advantageous magnetic alloys of iron are alloys containing at least noble earth elements, or especially advantageous magnetic alloys of iron are alloys containing at least one noble earth element and B and/or Co while advantageous metallic noble earth elements are Nd and Sm.
- the magnetic main material component is made on the basis of magnetically hard materials of the AINiCo or FeCoCr type.
- the non-magnetic main material component is beneficially created on the basis of a plastic material from the group of polymers or copolymers while it is especially advantageous if the polymer or copolymer is represented by substances from the PE, PP, PTFE plastic material group or ethylene copolymer with derivatives of methacrylic acid.
- detonation tubes are created where the magnetic substances contained in its body or package, at least in one layer enable magnetic separation of remainders of this tube from the mined material, which eliminates the hitherto considerable disadvantage of the necessity of manual separation of these remainders or in comparison with not performed separation reduces the risk of clogging or damaging processing equipment of broken stone contaminated by remainders of detonation tubes.
- detonation tubes made in accordance with the presented invention comply with requirements for cutting and rubbing resistance and the requirement for electric non-conductivity and also maintain their further benefits as high work safety and variability of creation of timed detonation networks as well as high resistance to water and humidity.
- a double-layer detonation tube was prepared.
- the first layer was based on ethylene copolymer with methacrylic acid and the second layer was based on PE containing 80 weight parts of PE and 20 weight parts of magnetite - FeFe 2 O 4 .
- the detonation tube prepared this way complied with the required rubbing and cutting resistance as well as the requirement of non-conductivity in accordance with relevant technical standards.
- a three-layer detonation tube was prepared.
- the first layer was based on the same composition as in example 1, the second layer was based on PE containing 85 weight parts of magnetite - FeFe 2 ⁇ 4 and the third layer was based on PE containing 75 weight parts of PE and 25 weight parts of magnetite - FeFe 2 O 4 .
- This detonation tube also complied with the required rubbing and cutting resistance as well as the requirement of non-conductivity in accordance with relevant technical standards.
- Example 3 The detonation tubes prepared in accordance with examples 1 and 2 were used for sets of electric detonators. After the execution of blasting work with the use of these sets the removal efficiency of remainders of detonation tubes from the mined rock with a magnetic field was tested. In both the cases 100% efficiency of removal of remainders of detonation tubes was proved.
- the equipment based on the presented invention can be used for blasting work where the resulting broken material is subsequently processed and the remainders of detonation tubes must be separated from the broken material.
