3. It's a trick. Bill Gates is not so powerful when he changes from 5 million to 7 million

4. Gravity separation or flotation is generally used in coal mine beneficiation
the most commonly used coal mine beneficiation equipment are: jaw crusher, ball mill, magnetic separator, high-frequency screen, vibrating screen, flotation machine, feeder, trough feeder, mixing bucket, bucket elevator, belt conveyor, high-efficiency thickener, disc granulator, shaker, spiral chute, spiral classifier, jig Tailings recovery machine, etc

the development of coal mine beneficiation equipment and beneficiation process is synchronous. The equipment is the foundation and the process is the leading. The successful development of a new type of coal mine beneficiation equipment often brings about changes in beneficiation process. The technical level of coal mine beneficiation equipment is not only the premise of the process level, but also directly affects the smooth flow and application of the proction process, Zhengzhou Zhongya machinery factory specializes in the proction of mineral processing equipment. For details, please visit the mineral processing equipment network of Zhengzhou Zhongya machinery factory.

5. Go to the labor bureau. We need to use the labor law to protect our rights and save the market. Do you have any contracts and signed work contracts that will help you

6. Should be no, underground coal mines are strictly prohibited to carry electronic procts, electronic watches are not allowed to bring, so it is still the official channel to go!

The air shaft is used as a special return air tunnel, which is ventilation. It has no other purpose. Of course, it can also be used for pedestrians in case of disaster. Underground is black, unless the installation of lighting, roadway cross-section is large enough, support is generally relatively strong, living environment, and the ground is similar.
