Technical Field
[0001] This utility model relates to the field of high-temperature resistant bag technology, specifically a high-temperature resistant bag for use in hot pores in mines. Background Technology
[0002] Deep mineral resource extraction has become commonplace, leading to an increasing number of geothermal wells, high-temperature goaf areas, and hot cavities. These areas often reach temperatures of 160℃-180℃, posing significant safety risks such as burns, leaks of harmful gases, and rock wall instability. Therefore, directional blasting is needed to seal these hot cavities and support the surrounding rock to prevent collapse. Traditional blasting packaging bags may suffer safety hazards or performance failure due to high temperatures; therefore, there is a strong market demand for high-temperature resistant packaging bags that can effectively isolate high temperatures, ensure blasting safety, and meet the requirements of harsh operating environments.

[0008] As a preferred technical solution, the booster bag is located in the lower middle part of the strip-shaped outer bag; this ensures that the high-temperature resistant detonating charge inside the booster bag can effectively detonate the cold explosive.
