The invention discloses a dual-axis synchronous vibrating screen for mine solid waste particles, which belongs to the field of vibrating screens. It is a dual-axis synchronous vibrating screen for mine solid waste particles. When it is inside, it will fall on the first filter first, and the ore falling on the first filter will control the rotation of the turntable at the same time, so that the turntable will drive the top block to rotate and jack up the first filter. At the same time, the main magnet block and The repulsion of the auxiliary magnet block makes the first filter screen lame more. When the first filter screen is lame up and down, the extension rod will drive the rotating plate to move up and down. After the rotating plate moves down, the mineral material will be introduced into the vibrating screen. Inside the body, when the first filter screen moves up and down, it will squeeze the air bag, so that the gas will be ejected and blow the impurities in the mineral material on the first filter screen through the air outlet. Through the above operations, the poured mineral material can be controlled , and when the efficiency needs to be increased, the speed of the mineral material shaken off by the first filter screen can be controlled by controlling the rotation speed of the turntable.

The invention discloses a pressure relief protection method for high-pressure sealing holes in coal rock formations, comprising the steps of: 1. drilling and extending a hole sealing device into the drilling; 2. injecting water into the drilling and sealing the holes; 3. protecting the hole sealing device Sealing holes and fracturing coal formations; 4. Stop fracturing; 5. Keep the pressure of the hole sealer step by step to reduce the pressure; 6. Recover the hole sealer. The invention transforms the one-way safety valve into a two-way safety valve, and cooperates with the pipeline control valve to meet the requirements of conventional high-pressure water injection into the drilling hole sealing and fracturing of the coal rock formation. The water pressure in the borehole is obtained from the table. When the fracturing is stopped, the two-way safety valve of the hole sealer cooperates with the one-way valve to maintain the pressure of the hole sealer that stops water injection, and the pressure is relieved step by step by adjusting the external pipeline stop valve and pressure regulating valve. , and the high-pressure water in the fracturing hole can flow out through the two-way safety valve, which realizes the in-situ pressure maintenance and relief of the hole sealer, ensures that the high-pressure rubber expansion hose is not easy to pop out of the drilling hole, avoids high-speed friction with the fracturing hole, and has a long service life.
