Basalt stone is a common building material that has been widely used in the industry due to its excellent performance. However, many people are not familiar with its mining methods. Let's take a look below.
1. Explosion rupture method: It uses the enormous energy released by explosives or other explosives to rupture basalt stones, which is now widely used and very useful.
2. Mechanical fracture methods: including four methods: cutting, rolling, and grinding.
3.The water jet rupture method is divided into two types:low-pressure high flow and high-pressure low flow.The former has a pressure not exceeding 2107Pa and is mostly used for hydraulic mining or coal mining;The pressure of the latter can reach several hundred million Pa and can be used to cut basalt stones.
4.Hot press fracturing method:A high-temperature gradient is formed in basalt stone,which utilizes the difference in thermal expansion coefficient of rock composition to form thermal stress,causing the rock mass to peel off or fracture more frequently.
The four methods introduced above are commonly used in the mining of basalt stones.You can have a brief understanding of them.
