The viscous explosive is mainly applied to top hole charging of mine pumping, and in the top hole charging blasting operation process, the required explosive has the characteristics of low mechanical sensitivity, safe operation process, small top hole charging return amount, large explosion power, higher water resistance and the like. If viscosity is too big, easily cause charge ware pumping pressure too big, have potential safety hazard and the problem of powder charge inefficiency, easily cause the jam of powder charge pipeline when powder charge in the pit to not only influence the powder charge, still increased the danger of powder charge process simultaneously. If the viscosity is too low, a large amount of explosive return of blast holes after charging is easily caused, so that the problems of unrealized charging and insufficient charging amount are caused, and greater potential safety hazards exist on site.
The granular sticky explosive needs to have moderate viscosity, namely, both cohesiveness and free-running property, and in the explosive charging process, certain cohesiveness can avoid the phenomenon of explosive return, and certain free-running property is also beneficial to preventing hole blockage in the explosive charging process. However, the existing viscosity measuring method can only measure the viscosity of liquid substances generally, and for finished products formed by mixing solid granular components such as granular sticky explosives, liquid oil phases and adhesives, no related viscosity measuring method exists. At present, the method for testing viscosity generally depends on the experience of technicians, and the method comprises the steps of picking a product by using an instrument, visually observing the wire drawing condition, and then judging whether the viscosity is proper or not by years of experience. Therefore, the method can not be used for judging the product performance in a standardized way and can not ensure the continuity of knowledge.
