定向爆破筑坝是根据炸药在岩石或士中爆破时必沿最小抵抗綫方向冲出这一基本原理,将炸药預先埋置在河谷二岸山体中的适当地点,用輔助药包来改造天然地形,造成定向坑,并用炸药爆炸时释出的巨大能量和大量高溫高压气体,将爆落岩块按指定方向拋擲到指定地点堆积起来,在短短几秒钟内,完成大量土石方的开挖和回填工作,以代替人工或机輪操作。
Directional blasting damming is based on the basic principle that explosives must be shot out in the direction of the minimum resistance line when explosives are rocked in blasting or blasting. The explosives are pre-buried in suitable locations in the mountainous areas of the river banks and the auxiliary kits are used to transform the natural terrain , Resulting in directional pit, and explosive explosions when the release of a huge amount of energy and a large number of high temperature and pressure gas, the rock will fall in the specified direction thrown to the designated location piled up in a few seconds to complete a large excavation of earth and stone and Backfill to replace manual or wheel operation.
