1、前言在爆破中,岩石的破碎效果,主要取决于炸药和泡泥的种类及爆破方法。爆破的起爆方法有正起爆和逆起爆,但是,对于这两种起爆方式所产生的爆破动态至今未作过明确的比较。在煤矿中,为了安全,有的矿同时使用水炮泥和砂炮泥.当这两种炮泥并用时,先装入水炮泥在安全方面是理想的,但是,先装1个水炮泥、后装砂炮泥,同先装砂炮泥、后装1个水炮泥在起爆效果上取决于矿工的经验。可是,对此都没有进行过爆破动态方面的比较。
1, Foreword In the blasting, rock crushing effect, mainly depends on the type of explosives and foam and blasting methods. Initiation methods for blasting are positive and antiknock. However, no clear comparison has been made so far on the blasting behavior of these two methods. In coal mines, for safety reasons, some mines use both gun mud and sand gun mud. When both gun mud are used in combination, gun mud first is ideal for safety, however, first install a gun Mud, after the installation of sand gun mud, with the first sand gun mud, after the installation of a water gun mud in the detonating effect depends on the experience of the miners. However, none of the dynamical aspects of blasting have been compared.
