Problems solved by technology

[0003] During the transportation process, clay blasting soil is mainly made of clay after drying, which is very easy to break. After being transported to the underground use site, the finished product rate is less than 20%, and the dried clay blasting soil is used before use. To ensure the blasting effect, it needs to be wet with water, which greatly affects the construction efficiency
Another disadvantage of clay gun soil sealing is that there is a high chance of adulthood running around
Due to the cohesiveness of the clay itself, the length of the finished product after drying is mostly about 50mm-150mm. In addition to the damage during the transportation process, most of the length does not exceed 100mm. Filling the blasthole of about 1m requires repeated filling. This will cause multiple wears on the gunpowder lead, which is very easy to cause blind shots and dead shots.
Another disadvantage of clay gun soil sealing is that blind guns are difficult to handle and pose a great safety hazard
Clay gun soil will be rammed and smashed by gun sticks during the loading process. Once it encounters a blind gun, it is very difficult to deal with
Another disadvantage of clay gun soil sealing is: after blasting, the blast dust is very large, and it often takes a long time for personnel to enter the construction again

Embodiment 1

[0013] As shown in the accompanying drawing, the new rapid blasthole sealing agent has a structure of composite membrane material, a cylindrical blasthole sealing shell 2 with a diameter of 28mm and a length of 400mm, filled with barriers in the cylindrical blasthole sealing shell. Combustion agent 3, dust suppressant 4, and binder 5 are used to seal the two ends of the cylindrical blast hole sealing shell with aluminum card materials to form a cone 2.

[0014] First, mix the flame retardant 3, dust suppressant 4, and binder 5 evenly, and use a filling machine to pour them into the prepared composite film cylinder blasthole sealing shell 2, and then use aluminum clips to clamp both ends. Tight, the assembly is completed, and different specifications can be made according to different requirements.

Embodiment 2

[0016] Drill holes according to the hole diameter and depth required by the design, and use a blower to clean up the floating or accumulated water in the holes. After the gunpowder is tied to the lead wire, it is sent into the bottom of the blast hole with a gun stick. According to the depth of the blast hole, a new type of rapid blast hole sealing agent is inserted into the blast hole and tamped with a gun stick. At the outermost end, you can use 100mm - 150mm clay gun soil for compaction, or directly tear the outer package of the new rapid blast hole sealing agent according to actual needs, and use a gun stick for compaction to ensure a better blasting effect.

[0017] Even if you encounter a blind gun during use, it is easy to handle due to its one-piece feature. You only need to hook the aluminum card to pull it out.

Abstract

The invention discloses a novel quick blasthole sealant, which solves the problems of long breeching time, high unexploded charge rate and big trouble in processing the unexploded charge of the traditional clay stemming. The novel quick blasthole sealant is characterized in that composite membrane materials are adopted; a cylindrical blasthole sealing shell 2 of which the diameter is 28mm and the length is 400mm is arranged; a fire retardant 3, a dust suppressant 4 and a binder 5 are filled into the cylindrical blasthole sealing shell 2; and two ends of the cylindrical blasthole sealing shell 2 are sealed by aluminum clip materials to form cones 2. The novel quick blasthole sealant has the advantages that gun dust after blasting is effectively lowered, the gun dust is quickly adhered, the construction time is shortened, the construction efficiency is improved, the open fire is inhibited, and the gas accident is reduced. The novel quick blasthole sealant is suitable for underground mining blasthole sealing.

Description

technical field [0001] The invention specifically relates to a novel rapid blasthole sealing agent, which belongs to the technical field of blasthole sealing in mine blasting operations, and is suitable for blasthole sealing agents for underground mining. Background technique [0002] As far as the inventor knows, at present, the blast mining operation under the mine well mainly adopts clay blasting soil to carry out blast hole sealing after the blasting is loaded, and there are many deficiencies in its manufacture, transportation and use. For example: [0003] During the transportation process, clay blasting soil is mainly made of clay after drying, which is very easy to break. After being transported to the underground use site, the finished product rate is less than 20%, and the dried clay blasting soil is used before use. To ensure the effect of blasting, it is also necessary to wet it with water, which greatly affects the construction efficiency. Another disadvantage...
