我国露天矿的控制爆破技术,近几年来有了较大发展。临近边坡的预裂爆破、光面爆破、缓冲爆破、微差爆破等,已在生产中推广应用,并取得了良好效果。本文所讨论的控制爆破技术问题,是从广义方面考虑的,认为在今后露天矿生产爆破中应把控制爆破技术作为发展的主攻方向。笔者认为,露天矿控制爆破技术的内容,应包括控制爆破块度、控制爆破公害和提高炸药能量利用率三个主要方面。这三方面的问
Controlled blasting technology of open pit mine in our country has been greatly developed in recent years. The presplitting blasting, smooth blasting, bursting blasting and micro-blasting blasting near the slope have been widely applied in production and have achieved good results. The control blasting technology discussed in this paper is considered in a broad sense. It is believed that the control blasting technology should be the main direction of development in the blasting of opencast mine in the future. The author believes that the content of opencast control blasting technology should include the control of blasting block, control of blasting pollution and improve the energy efficiency of explosives in three main areas. These three aspects of the question
