Abstract
Description
Technical Field
[0001] The present invention relates to the field of detonators, and in particular to a method for testing the detonation capability of an intelligent coal detonator. Background Art
[0002] Coal mine permissible electronic detonator initiator, referred to as "coal mine permissible detonator", is an advanced equipment specially used for underground blasting operations in coal mines. It uses electronic control technology to accurately control the timing and sequence of explosions, significantly improving the safety and efficiency of blasting. Compared with traditional instantaneous or delayed electric detonators, electronic detonators have the characteristics of digital control and programming. Different detonation times and explosion sequences can be set according to actual needs, effectively reducing blasting vibration and flying rocks, and protecting the safety of surrounding structures.
[0003] The Chinese invention patent application number: CN201210015859.0 proposes an intelligent detonator and intelligent detonation method for use in coal mines. The intelligent detonator for use in coal mines includes a microprocessor, a positioning module, a communication module, a coal dust and gas detector, and a detonation module. The intelligent detonator and detonation method for use in coal mines of the present invention can monitor bulk explosives, packaged explosives, detonating equipment, and qualification information. Detonation is allowed only when the blasting conditions are met and the remote monitoring center issues a detonation permission information.
[0004] However, the existing detonators have some shortcomings in the testing process and still need to be improved, and their reliability and safety are insufficient: in the existing technology, there may be a lack of comprehensive and systematic testing methods to evaluate the performance of detonators in various environments, resulting in their reliability and safety in actual use not being fully verified. Existing testing methods may only focus on some performance indicators of the detonator, while ignoring electrical performance, long-term stability and performance under different environmental conditions, making it impossible to fully evaluate its performance.
[0005] In the case that the existing technology fails to conduct tests under various conditions of air pressure, oxygen concentration, humidity and temperature, the environmental adaptability of the detonator is unknown and may not be guaranteed to work properly in extreme coal mine environments.
[0006] The existing technology fails to continuously optimize products through comprehensive testing, which may result in mediocre product quality and fail to meet the market demand for high-performance detonators. Detonators that have not been rigorously tested may fail to meet international and domestic safety standards and regulatory requirements, increasing legal and safety compliance risks. Products in the existing technology may fail and unexpectedly shut down in the field due to insufficient testing, causing users to incur higher maintenance costs and production losses. Unoptimized detonators may result in waste of energy and materials, fail to meet the requirements of environmental protection and sustainable development, may cause users to encounter problems during use, and reduce user satisfaction and loyalty. Therefore, we have made improvements to this and proposed a method for testing the detonation ability of smart coal detonators. Summary of the invention
