这个讨论试图对围绕着铵油炸药大直径炮孔装药的起爆药包选择上存在的某些含混问题作一澄清,其要点如下:1.总的思想倾向是认为爆速和爆压对于岩石破碎过程的重要性不象曾经相信的那么大,某些感觉是它们的重要性很小或者不重要。2.铵油炸药柱被起爆后展示出一个由起爆药包算起达几倍炮孔直径的瞬变速度区。3.一磅重熔铸起爆药包比组合起爆药包所产生的瞬变速度低,只要低瞬变速度不靠近破坏点它就不会严重影响爆破过程。4.在冲击和热的(铝化的)组合起爆药包所产生的瞬变速度之间无明显的区别。5.铵油炸药中的终极稳定状态速度不受起爆药包类型和尺寸的影响。6.高能组合起爆药包是保证铵油炸药在不利条件下起爆的良好的起爆物,对难爆地区能提供补充能量。7.起爆药包必须放在难爆破的地带,它可能位于台阶的根部亦可能位于爆破料物的坚硬区段,在超钻内放置起爆药包可能加强地震效应。8.铵油炸药一旦达到稳定状态速度,就以该速度可靠的传播,所以为保证传播而设置补充起爆药包是不必要的。9.轴向起爆虽然是一种目前存在的起爆技术,但是它没有显著的优点足以平衡它所需用的较高爆破费用。10.孔内导爆索依条件不同可能使铵油炸药产生钝感效应,或者能产生轴向起爆。
This discussion attempts to clarify some of the ambiguities that exist around the selection of detonating kits for large diameter shots of ammonium explosives. The main points are as follows: 1. The general idea is to think of detonation and detonation as a function of rock fragmentation The process is less important than it was once believed, and some feel that their importance is insignificant or insignificant. 2. Ammonium oil explosive column was detonated to demonstrate a blast from the bag count up to several times the diameter of the muzzle velocity zone. 3. A pound cast booster package than the combination booster package generated by the transient speed is low, as long as the low transient speed is not near the destruction of the point it will not seriously affect the blasting process. 4. There is no significant difference between the transients produced by the impact and hot (aluminized) combination packs. 5. The ultimate steady state speed in ammonium explosives is not affected by the type and size of the priming bag. 6. High-energy combination of detonating kits to ensure the explosive detonated under unfavorable conditions, a good detonating material, to provide additional energy in areas of detonation. 7. The detonating kits must be placed in a refractory zone which may be located at the root of the step or in a hard section of the blasting material. Putting the detonating kits in the super drill may enhance the seismic effect. 8. As soon as the ammonium oil explosives reach a steady state speed, they are reliably transmitted at this rate, so it is not necessary to set up replenishment of detonating kits for the purpose of ensuring transmission. Although axial detonation is a presently available detonation technique, it has no significant advantage enough to balance the higher blasting costs it requires. 10. Hole detonating cord according to different conditions may have a detrimental effect of ammonium oil explosives, or can produce axial detonation.
