[0002] Mining blasting engineering refers to the technical means of destroying and crushing rocks in mines by using the explosion energy through the principle of explosion. Its purpose is to separate the ore from the vein and provide convenience for subsequent mining work.

[0003] In mining blasting projects, deep hole blasting is a commonly used blasting method. As an important parameter of deep hole blasting, the chassis resistance line is of vital importance to the blasting effect and safety. At present, the industry usually uses traditional measurement tools and methods to measure the chassis resistance line, but there are problems such as low measurement accuracy and complex operation.
