Embodiment Construction
[0008] As shown in the figure: in the explosive hole 1, a cushion layer 2 is built according to the shape of the inner wall of the explosive hole, and explosives 3 are filled between the cushion layer 2 and the inner wall of the explosive hole.
[0009] The pressure that the gas produced when the explosive explodes acts on the rock is similar to that without a cushion. After the explosive hole is enlarged, the contact surface between the explosive and the rock increases, and the explosion power increases accordingly. However, due to the increase of the cushion layer, so that the purpose of saving explosives can be achieved.

The invention discloses a new method for blasting. A cushion coat is built in an explosive containing hole, the outside shape of the cushion coat is similar to the shape of the inner wall of the explosive containing hole, the outer wall of the cushion coat has equivalent spacing with the whole inner wall explosive containing hole, and explosive is filled between the cushion coat and the inner wall of explosive containing hole. The invention overcomes the defects of explosive waste and environment pollution during mammoth blasting, and saves explosive.
Description
Technical field [0001] The invention relates to the field of blasting operations, in particular to a large-scale blasting method that can greatly save explosives and reduce environmental pollution. Background technique [0002] At present, Kaishan Blasting is to make a hole in the middle of the blasting site and put explosives into it to blast. When the explosive explodes, the effect on the blasting object depends on one, the pressure generated during the blasting, and the other is the contact surface with the explosive. To increase the explosive power, the area of the explosive hole must be increased. Therefore, when drilling the holes for explosives, in order to increase the explosive power, generally the holes for explosives will be dug relatively tall, so that explosives will have to be loaded in a lot, which will waste explosives and pollute the environment. Contents of the invention [0003] In order to overcome the problems of wasting explosives and polluting th...
