[0002] Liquid oxygen is oxygen in its liquid form. It is a light blue liquid with strong paramagnetic properties. Liquid oxygen is highly oxidizing and reacts with most substances, releasing large amounts of energy. Because the expansion of liquid oxygen occurs under controlled conditions, it significantly reduces safety risks during operations. Traditional explosive blasting methods have been gradually restricted and eliminated, necessitating the need for an expansion-induced fracturing device that uses liquid oxygen in a hole.

[0003] The expansion fracturing device that fills the hole with liquid oxygen is a new type of rock crushing technology. It uses the characteristic of liquid oxygen that it quickly vaporizes after being heated instantly to generate high-pressure gas. These gases form high-pressure stress in the rock drill hole, causing the rock to crack and move. Previous in-hole liquid oxygen filling devices may be affected by many factors such as technical limitations, safety factors, economic costs and operational convenience.

[0029] Working principle: When the device needs to be used, first start the second hydraulic rod 20, and through the extension or telescoping of the second hydraulic rod 20, drive the second connecting block 21 to rotate on the second connecting column 22.
