Description
Technical field
The invention belongs to blasting engineering field, particularly about a kind of umbrella shape screens hanger and utilize umbrella shape screens to hang
The hanging device method to blast hole projectile filling.
Background technology
In blasting engineering, on to, level, it is lower that to low-angle dip, (low-angle dip refers to that the inclination angle in big gun hole can rely on heavily less than powder charge
Power slips into the angle in big gun hole, generally less than 30 °) deep blind hole (blind hole refers to big gun hole one end open) powder charge is a difficult problem, special
It it not the occasion needing spaced loading and Uncoincided charge.For level or low-angle dip blind hole, common loading method has two
Kind, one is the method that with rod member, medicated bag (or powder stick) and sept (such as waste paper) are pushed big gun hole piecemeal, and the method efficiency is low,
And thrust that medicated bag below bears is increasing, it is easy to cause packing explosive damaged or deformation, cause blocking big gun hole and nothing
Method continues powder charge.Another kind of method is to use charging machine, is sent in hole by bulk explosive pipeline, although this method efficiency
Height, but spaced loading accurately and Uncoincided charge can not be realized.To blind hole powder charge on for, then make due to the gravity of explosive
With, in hole explosive be stressed uneven (the most down, pressure is the biggest, and explosive density is the biggest), spaced loading and Uncoincided charge difficult
To realize, difficulty and the precision controlling difficulty of powder charge are bigger;And, use and manually push medicated bag, machinery (with pipeline) dress piecemeal
The method of medicine is difficult to accomplish No leakage powder charge (due to blocking difficulty in bottom, big gun hole during powder charge, explosive is easily revealed).
Above-mentioned powder charge problem needs new technical scheme to solve.
Summary of the invention
It is an object of the invention to provide a kind of umbrella shape screens hanger and utilize umbrella shape screens hanger to blast hole projectile filling
