We are not allowed to use explosives to explode the mountains, so how can we mine the mountains? Now the way of blasting mountains with explosives is illegal, which method is better for mining mountains? Recently, a friend asked about the mining methods of mines. The small mine will introduce to you today the main methods of non-explosive mining.
1. What is carbon dioxide blasting?
One of the main methods of non-explosive mining is the carbon dioxide blasting method(CO2 rock demolition system). This method uses a carbon dioxide blasting device, which uses carbon dioxide gas to be converted into liquid under a certain high pressure. The liquid carbon dioxide is compressed into the blasting cylinder by a high-pressure pump, and then safety membranes, rupture discs, heat conduction rods, sealing rings and other components are installed. Then it is connected to a power source for heating, and the liquid carbon dioxide is gasified to produce a high-pressure shock wave to split the ore.
2. What are the characteristics of carbon dioxide blasting?
1. High security. Carbon dioxide uses gas blasting, which is safer than explosives.
2. The gas is not a civilian explosive product and does not require approval, which saves a lot of tedious procedures.
3. The impact is small. There is no destructive vibration and short wave during the carbon dioxide blasting process, and at the same time, the dust is small, and the impact on the surrounding environment is small.
4. The operating environment will not be affected. It can be used in complex operating environments such as coal mines and mines.
5. The equipment is easy to purchase, and some devices can be reused.
6. The blasting power is large, and the rock body is large after blasting.
Carbon dioxide blasting（CO2 rock blasting） is one of the most widely used methods of mining. Although it is a non-explosive method, we still have to pay attention to the safety during use.
