1976年下半年,昆明工学院爆破实验室在昆明有色冶金设计院及海口水泥厂的大力支持和配合下,初步研制成功一种无触点可调式微差爆破仪。这种专供露天矿山使用的微差爆破仪的研制成功,不仅为推广微差挤压爆破作出贡献,并为进一步寻求这种新的爆破技术的合理参数提供新的科学试验手段。现将它的结构原理、主要特点及雷管试爆情况作一简单介绍,以资参考。一、结构原理无触点可调式微差爆破仪是根据可控硅无触点延迟开关原理制成的控制仪器。它通
The second half of 1976, Kunming Institute of Blasting Laboratory in Kunming Nonferrous Metallurgy Design Institute and the strong support of cement plant in Haikou, the initial successful development of a non-contact adjustable micrometer breach detector. The successful development of this microtube blasting instrument specially for open pit mine not only contributes to the promotion of differential extrusion blasting, but also provides a new scientific test method for further searching for reasonable parameters of this new blasting technique. Now it’s structural principle, the main features and the detonator test burst situation for a brief introduction to reference. First, the principle of structure Non-contact adjustable micro-differential burst detector is based on SCR contactless switching delay control principle made of the instrument. It passes
