塑料导爆管是一种新型的非电力起爆材料，我队经试用后已正式用于生产。共掘进坑道150米（净断面为3.6平方米），消耗导爆管约4000米，证明该型导爆管性能稳定，导爆可靠，为起爆器材的优良产品。一、导爆管的结构及原理导爆管是由中空塑料管的内壁上涂以一薄层高能粉状炸药所构成，是根据近代稳定低速爆轰理论和冲击波传播的管道效应原理设计制成的（见图1）。当它的一端受到足够强大的击爆能的作用时，冲击波击穿
Plastic detonating tube is a new type of non-power detonating material, the team has been formally used for trial production. A total of 150 meters tunneling (net section of 3.6 square meters), consumption of about 4000 meters detonating tube, proving that this type of detonating tube performance is stable, reliable detonation, detonating equipment for the excellent product. I. Structure and principle of detonating tube The detonating tube is made of a thin layer of high-energy powdered explosive coated on the inner wall of a hollow plastic tube. It is designed and manufactured according to the modern stable low-velocity detonation theory and the pipeline effect principle of shock wave propagation (See Figure 1). Shockwave breakdown occurs when one of its ends receives a sufficiently powerful strike energy
