矩形掏槽光面爆破法创新应用

Innovative application of rectangular cut smooth blasting method

控制爆破在地下开采过程中被广泛应用,目前所用控制爆破有预裂爆破、光面爆破、微差爆破、挤压爆破、定向抛掷爆破等爆破技术,均能达到各自控制目的,并能取得良好效果,其爆破进尺多少根本在掏槽眼自由面大小的布局,掏槽眼与自由面合理布置至关重要。

controlled blasting is widely used in underground mining, and the controlled blasting is used for pre splitting blasting and blastingSurface blasting, blasting, blasting, directional throwing blasting blasting technology, can achieve the objective of their control, and can achieve good results, the blasting footage simply cut the size of the eye in the free surface layout, reasonable arrangement of holes and the critical cut free surface.
