[0002] As the most popular safe, efficient, low-cost and large-scale technical means in rock excavation production, deep hole blasting is widely used in many large-scale earthwork projects such as open-pit mining, site leveling and roadbed excavation. The economic benefit of blasting is related to blast hole planning and explosive dosage. Different blast hole spacings and explosive dosages will affect the blasting effect and to a certain extent affect the project progress. And accurate blast hole layout and hole depth measurement can more precisely control the explosive dosage, thereby improving the economic benefit while meeting the project requirements.

[0003] Before carrying out mine blasting, steps such as hole digging and burying explosives are required. The existing hole digging operations often estimate the distance between blast holes through inaccurate measurement for blast hole layout, and the depth of the dug holes will also have certain errors due to the tools used. The subjective measurement and layout methods of people will make the distance between blast holes and the amount of explosives used inaccurate, thereby affecting the blasting effect. If the error is large, the possibility of more serious danger will increase. In order to overcome these disadvantages, the utility model provides a digital blast hole plug.
