SU32710A1 - The method of storage of explosives in underground warehouses - Google Patents

Description

In connection with a significant increase in productivity in the new mines, the question arose of increasing the capacity of underground dynamite warehouses, since, with the existing permitted capacity, such a situation might arise that, every day during the shift, explosives would have to be delivered to the mines to the extreme flow of the recoverable loads . The latter provision may pose a greater danger than it is increased; -: e capacity of underground dynamite warehouses.

The proposed method is meant, on the one hand, not to resort to the increased capacity of dynamite warehouses, to avoid a counter-flow of explosives and cargo, and on the other hand, when building new underground warehouses, ordinary or increased capacity, create conditions in the case of an explosion a warehouse, for attenuating the destructive effect of the force of an explosion, and also for attenuating the air wave accompanying the explosion.

In the drawing, fig. 1 shows, for the sake of explanation of the proposed method, an underground storage for explosives D with a longitudinal section and FIG. 2, the same, section along the LB line in FIG. one.

According to the proposed method, in order to reduce the destructive effect

(3-19)

explosives in the event of their explosion, in a place intended for the location of a warehouse of explosives, it is preliminary. one or more cameras L are held as much as possible. In the middle part of the chamber, one or several compartments 2, 3 of a warehouse are easily destroyed; a fire-resistant material, for example, from lean concrete with gravel, is not more than 2 g. ", And the gap between the structure of the compartments and the walls of the chamber: nothing to fill, so that the air of the chamber represents the buffer that paralyzes the destructive effect of the force of the explosion. To reduce the strength of the air wave (except for the required measures according to the rules of safety; :) from the surface, one or several hide /, 5, 6, which can be used one time, not only for broadcasting; and compartments, but also for the descent of the explosives on the foot of a vis-à-vis the troika, using one of the well-known equipment for the transport of objects in underwear.

In the latter case, the question of increasing the capacity of the underground | sig: Dov, in the opinion of the inventor,:. Is completely eliminated, so is the equipment for launching the cartridges. M,: 1 hmm. design with a capacity greater than or corresponding to the consumption of explosives in a shift.

The subject matter of the invention.

1. A method of storing explosives in underground warehouses, characterized in that the explosives, in order to reduce their destructive action in the event of an explosion, are placed in the center of the warehouse space so that

that between the explosive and the walls I, the ceiling and the floor of the warehouse, there is a considerable free space.

2. Supply of explosives from the surface of the earth during their storage according to the method described in paragraph 1, characterized in that the explosive materials are supplied to the warehouse via pipes laid along existing workings or through specially constructed wells for this purpose.
