Consolidation water stemming for blasting blockage

Abstract

The invention discloses consolidation water stemming for blasting blockage, which is formed in such a way that mixed powder is placed in a bag body, and is sealed and soaked in water, wherein the mixed powder comprises the following components in part by weight: 10-15 parts of attapulgite, 6-12 parts of chlorinated lime, 3-5 parts of gypsum, 1-3 parts of resin sweller and 0.1-0.4 part of sodium dodecyl sulfate; and the bag body is made of permeable papers. The consolidation water stemming has the advantages of simplicity and convenience in operation and low production and use cost; and the water curtain formed after explosive explosion can play a role of settling dust, degrading poisonous and harmful gas, dampening flame, reducing temperature and the like, and particularly, greatly reducing risks caused by methane gas accidents.

Description

technical field [0001] The invention relates to a blasting mud used for blasting blockage, in particular to a kind of consolidated water blasting mud used for blasting plugging, which is suitable for drilling and blasting work places such as mine roadways, hydraulic tunnels, traffic tunnels and the like. Background technique: [0002] Bunker mud is used to block the muzzle in the drilling and blasting operation site. Because the gun mud itself has a certain quality, it can block the explosive gas rushing to the orifice when the explosive explodes, so that the high-pressure gas in the hole can The time is extended, thereby enhancing the blasting effect. On the other hand, the retarding effect of the gun mud on the explosive gas also makes the explosives react more fully, thereby reducing the generation of toxic gases. [0003] At present, the blasting operation site generally adopts on-site soil extraction to block the blast hole. Due to the difficulty of obtaining soil in m...

AI Technical Summary

Problems solved by technology

[0003] At present, the blasting operation site generally adopts on-site soil extraction to block the blast hole. Due to the difficulty of obtaining soil in most operation sites, especially in underground mines and desert areas, and the troublesome and labor-intensive plugging of blasting mud, it is basically used at present. non-clogging blasting

Non-clogging blasting not only has high blasting cost and poor blasting effect, but also increases the content of toxic gas, making it difficult to guarantee blasting safety. Therefore, it is of great significance to develop a blasting clay that is easy to plug, has good plugging effect and low production cost.
