Explosive device capable of recycling dust and its application method

Abstract

The invention discloses a blasting device capable of achieving cyclic utilization of dust and a using method of the blasting device. The device comprises a heating unit, an oxygen concentration detection unit, a temperature monitoring unit, an early warning unit and a control ignition unit. Compared with the prior art, the device plays the advantage of controllable dust explosion, and is suitablefor tunnel blasting, quartering mining engineering, expansion coal mine fracture and the like; the advantages of large destructive power of common explosives can be reserved, and the purpose of controllable and cyclic utilization can be achieved; the effects of being safe and reliable in use are achieved, flour, metal powder and other dust which does not contain pollutants can be selected according to the environment-friendly requirement, so that the requirements of environmental protection are met; and due to the fact that the device can be recycled, and the price of the dust is low, the purpose of reducing the engineering blasting cost can be achieved.

Description

technical field [0001] The invention relates to the field of blasting engineering, in particular to a blasting device capable of recycling dust and a method for using the same. Background technique [0002] Blasting includes gunpowder blasting, carbon dioxide blasting and static explosion splitting. Gunpowder blasting is extremely risky. After the blasting, there will be a strong impact force. The impacted gravel can easily hurt the surrounding construction personnel. At the same time, the harmful substances produced by the explosion will pollute the environment. Carbon dioxide blasting technology is an emerging technology, its explosive power is smaller than that of gunpowder technology, and carbon dioxide energy-gathering materials are more expensive, resulting in higher cost of carbon dioxide blasting. Static explosion splitting technology is less powerful in actual engineering use, and often fails to achieve the expected effect of the actual project, and the equipment i...
