三角形钻孔钻机

Triangular Hole Drill

针对现有圆孔在爆破中不能起到聚能作用,研制一种三角形钻孔钻机;钻机将半径为R的圆孔加工成截面边长为2R的三角形的孔,提高炸药穿透能力,减少炸药消耗量,提高经济效益。

In view of the existing round hole cannot efficiently gather energy,this paper develop a triangular hole drill.a round hole with a radius R can be processed into a triangular hole with radius2 R. Reducing the consumption of explosive,the penetration ability of explosive and the economic benefit will be improved.
