Research of the Application of the Ultra-deep Hole Blasting Technique

The ultra-deep hole blasting is a new technology. The detailed scientific demonstration is carried out in this article, from stabilizing the detonation, improving the blasting effect and efficiency, reducing the dynamite consume, increasing the economic benefit and so on. In the circumstances of the benches narrow in the open cast mine, it is necessary to improve storage explosion of rock, accelerate stripping , increase stripping ratio of the production, ensure the sustained stability of ore production, accelerate the formation of cross-level railway and the automobile provisional road etc. These respects also had been seriously studied and researched.
