Research On Reliability Of Non-electric Detonating System

Along with society’s unceasing progress and the development, science and technologyprogressing by leaps and bounds, the new demolition technology, the demolition equipment renewal,causes the modern demolition technology the application domain also gradually to expand. Recentlyseveral years developed because the non-electric detonation demolition equipment in the production,the transportation, the storage and the use compared the security, the operation was simple, couldanti-power output disturbances and so on stray currents, static electricity, radio frequency electricity,the stability be high, obtained the widespread application in the modern demolition process. Howdesigns the stable reliable non-electric detonation network system, demolishes the successful corequestion. This article mainly aims at the non-electric conductance cartridge igniter blasting capdetonation network system the reliability to carry on thorough launches the analysis and the research.Non-electric conductance cartridge igniter detonation network in actual utilization although has thesecurity reliable, the operation simple, the transportation storage convenience and can realize meritseasily and so on multistage elemental error detonation, but leads the cartridge igniter detonationnetwork also to have a very big problem, the network cannot use the measuring appliance toexamine. Although has some to demolish the worker and the manufacturer has done someexperiments and the inference under the different environment, also proposed some experiences andthe opinion to the non-electric detonation network reliability. However, the reliability of non-electricblasting network in experience and still intuitive feeling judging, for blasting for this special industry,unable to accurately grasp the initiation network, there will some more or less cannot be aware ofthe security risks, so the reliability of non-electric blasting network for further research and analysisis very necessary.Affects the non-electric detonation network reliable factor to have very many, mainly dividesinto the human factor, the demolition equipment factor and the environmental factor three parts. Thehuman factor mainly is demolishes the design to make a mistake and to construct the operation fault;The environmental factor mainly has explodes the artillery hole destruction detonation network firstand so on; The demolition equipment factor mainly is the demolition equipment unqualified, theblasting cap accurate knock rating low two aspects.This article is analyzing the non-electric conductance cartridge igniter detonation networkthoroughly the structure and in the characteristic foundation, to causes each kind of factor usingaccident tree analytic method (FTA) which the demolition network expires to carry on the analysis,and analyzes the appraisal demolition network using the smallest cutset and the most trail collection the margin of safety. In view of the common non-electric conductance cartridge igniter detonationnetwork, unifies predecessor’s research experience, the utilization most alley law and the recurrenceformula law calculates its margin of safety, and unifies the project example to come the checkingcalculation operational method.
