The invention provides a coal dust continuous explosion prevention system for a coal mine construction roadway and a using method of the coal dust continuous explosion prevention system. The coal dust continuous explosion prevention system for the coal mine construction roadway comprises a main pipeline and explosion-proof units which are arranged in the coal mine construction roadway, wherein each explosion-proof unit comprises a water spraying structure and an impact self-starting structure. According to the coal dust continuous explosion prevention system for the coal mine construction roadway and the using method of the coal dust continuous explosion prevention system, the main pipeline and the explosion-proof units form the coal dust continuous explosion preventing system, a pure mechanical structure is adopted for operation, and when the system is used, the system is not affected by the electricity utilization condition and can keep the normal operation state all the time; and by means of the independent explosion-proof effect of each explosion-proof unit, continuous explosion caused by shock waves generated by explosion can be effectively prevented, the system can be used as an emergency protection measure in a coal mine construction roadway and can be used together with an existing sensor explosion-proof device, and then the safety performance in the coal mine construction roadway is greatly improved.
Description
technical field [0001] The invention relates to the field of coal mine construction, in particular to a coal dust continuous explosion prevention system for a coal mine construction roadway and an application method thereof. Background technique [0002] Coal mine dust is the general term for various mineral fine particles produced in the coal mine production process. Coal dust is extremely harmful. It not only pollutes the working environment, but also affects the health of miners. [0003] Because coal is a combustible substance, if its dust floats in the air and reaches a certain concentration, and there is enough heat source to ignite the coal dust, a coal dust explosion can occur, which is one of the major disasters in coal mines, and the shock wave generated by the coal dust explosion can raise The coal dust deposited in the roadway was aroused, and continuous explosions occurred, even affecting the entire mine. [0004] In related technologies, in order to avoid coal...
