冶金矿山采用定向爆破技术堆筑尾矿坝的基础坝,实践证明,这种施工方法能加快工程进度,满足尾矿坝技术要求,防渗处理简单,节约大量的投资和劳动力。这种施工方法值得推广。定向爆破是使爆落的岩石严格地按照特定的方向运动,并且堆筑成一定的形状。人们从爆破工程实践中,总结并逐步发展了控制爆破方向的很多方法。其中有崩塌筑坝,就是在陡 Metallurgical mine uses directional blasting technology to build the foundation dam of the tailings dam. Practice has proved that this construction method can speed up the construction schedule and meet the technical requirements of the tailings dam. The anti-seepage treatment is simple and a large amount of investment and labor are saved. This method of construction is worth promoting. Directional blasting is to blast the rock in strict accordance with the specific direction of movement, and piled into a certain shape. People from blasting engineering practice, summed up and gradually developed a number of ways to control the direction of blasting. One of the collapse of the dam, is steep
