Abstract
The utility model discloses a high-temperature-resistant blast hole loading structure which comprises a high-temperature-resistant pipe that is placed in a blast hole. The lower part in the high-temperature-resistant pipe is filled by explosive and a detonation component, and the upper part is filled by filling material. According to the high-temperature-resistant blast hole loading structure, firstly the high-temperature-resistant pipe is placed in the blast hole, and then the explosive is loaded in the high-temperature-resistant pipe. Because of heat insulation function of the high-temperature-resistant pipe, explosive loading and explosion can be safely performed even when the temperature of the blast hole is high. Therefore, the high-temperature-resistant blast hole loading structure has the following advantages: capability of being used for safe loading and explosion in high-temperature environment, no restriction by conditions such as explosive, and convenient construction.
Description
Technical field
The utility model relates to a kind of blast hole projectile filling structure, is specifically related to a kind of high temperature resistant blast hole projectile filling structure.
Background technology
Traditional charge constitution is bottom powder charge in the big gun hole, and top is clogged by padding.But for fire district blast working,,, can not satisfy demand for security, can not carry out blast working if there is not high temperature resistant explosive such as the colliery blasting construction serious to the spontaneous combustion of coal seam phenomenon.Therefore, traditional charge constitution receives the restriction of conditions such as explosive during blast working in the fire district, and it is not convenient to construct.
Therefore, need to improve traditional charge constitution, can be in hot environment safety carry out charge explosion, do not receive the restriction of conditions such as explosive, construction is convenient.
Summary of the invention
In view of this, the utility model provides a kind of high temperature resistant blast hole projectile filling structure, can be in hot environment safety carry out charge explosion, do not receive the restriction of conditions such as explosive, construction is convenient.
The high temperature resistant blast hole projectile filling structure of the utility model comprises the high-temperature resistant tube of inserting in the big gun hole, and explosive and detonation element are equipped with in the bottom in the said high-temperature resistant tube, and top is clogged by padding.
Further, be provided with heat insulating mattress bottom the said high-temperature resistant tube;
Further, said high-temperature resistant tube is a pvc pipe;
Further, said explosive is an emulsion;
Further, said detonation element is a primacord;
Further, said heat insulating mattress is an asbestos gauge.
The beneficial effect of the utility model is: the utility model is at first inserted high-temperature resistant tube in the big gun hole, the explosive of in high-temperature resistant tube, packing into again because the heat-blocking action of high-temperature resistant tube, even big gun hole temperature is high, also can be safe carry out charge explosion; Therefore, the utility model can be in hot environment safety carry out charge explosion, do not receive the restriction of conditions such as explosive, construction is convenient.
Description of drawings
For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model is done further to describe in detail below, wherein:
Fig. 1 is the structural representation of the utility model;
The blasting circuit sketch map that Fig. 2 connects for the charge constitution that uses the utility model.
The specific embodiment
Below will be with reference to accompanying drawing, the preferred embodiment of the utility model is carried out detailed description.
Fig. 1 is the structural representation of the utility model, and is as shown in the figure, and the high temperature resistant blast hole projectile filling structure of the utility model comprises the high-temperature resistant tube 1 of inserting in the big gun hole, and explosive 2 and detonation element 3 are equipped with in the bottom in the said high-temperature resistant tube 1, and top is by padding 4 fillings.
In the present embodiment, said high-temperature resistant tube 1 bottom is provided with heat insulating mattress 5; Heat insulating mattress 5 can be further with explosive 2 and big gun span warm.
In the present embodiment, said heat insulating mattress 5 is an asbestos gauge.
In the present embodiment, said high-temperature resistant tube 1 is a pvc pipe; The heat-blocking action of pvc pipe can guarantee to accomplish charge explosion smoothly in safety below 120 ℃.
In the present embodiment, said explosive 2 is an emulsion.
In the present embodiment, said detonation element 3 is a primacord; Certainly, detonation element also can be other detonation elements such as igniting primer, detonating capsule.
The blasting circuit sketch map that Fig. 2 connects for the charge constitution that uses the utility model; As shown in the figure, in each big gun hole, all insert high-temperature resistant tube 1 earlier, in high-temperature resistant tube 1, pack into again explosive 2, detonation element 3 and padding 4; At last the detonation element in each big gun hole 3 is connected initiation ends 6 and form blasting circuit; Because the heat-blocking action of high-temperature resistant tube 1, even big gun hole temperature is high, also can be safe carry out charge explosion.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although the preferred embodiment through with reference to the utility model is described the utility model; But those of ordinary skill in the art should be appreciated that and can make various changes to it in form with on the details, and the spirit and the scope of the utility model that does not depart from appended claims and limited.
