1985年4月17日,法国炸药能小组,在图卢兹召开了采石场和露天矿更好地使用炸药会议。一、岩石条件与爆破参数的关系 1.裂隙情况对于确定爆破参数和爆破效果起着极其重要的作用。岩石条件影响凿岩精度,因此,也影响爆破效果。 2.岩体裂隙的不连续面几何尺寸决定了岩层厚度和岩块高度,因此,也决定了岩
On 17 April 1985, the French Explosives Group, at Toulouse, held a conference on the better use of explosives in quarries and opencast mines. First, the relationship between rock conditions and blasting parameters 1. Crack situation for the determination of blasting parameters and blasting effect plays an extremely important role. Rock conditions affect rock drilling accuracy, therefore, also affect the blasting effect. 2. The discontinuity geometry of the rock mass fissures determines the thickness of the rock formation and the height of the rock mass and thus also determines the rock
