With the advance of urbanization, more and more buildings cannot meet the requirements of modernization and face the trend of being dismantled, the urban environment is complex, vehicles are endless, the population is dense, important buildings are concentrated, and the environment of the building to be dismantled is fully considered when the demolition blasting is adopted so as to avoid severe influence on the surrounding environment caused by blasting. In urban demolition blasting, the generation of flying stones is inevitable, once the flying stones are uncontrollable, the life health of people can be harmed, and economic loss is brought, so that the safety control of blasting the flying stones is one of important work of demolition blasting. In order to reduce the generation of flying stones, a common control measure is to strengthen protection, and materials such as bamboo basketries are adopted for covering, so that the purposes of reducing the initial speed of the flying stones and further reducing the energy of the flying stones are achieved.

The flying stone protection measures usually concern the blasting quality and the blasting effect, and even directly influence the image of an enterprise sometimes, so the flying stone protection is indispensable, a large amount of dust can be generated in the blasting process, and the surrounding air quality can be seriously influenced if the dust is not treated.
