Coal mine output detection is mainly aimed at small coal mines, which is a technical means to ensure national tax revenue and fair trade. If you change the data, you have to pay more taxes when the data gets bigger, and the mine owner will definitely not allow it; If the data is reduced, the tax revenue will be reduced, which constitutes tax evasion and serious violation of the law. If you suspect that the data is inaccurate, you can contact the local technical supervision bureau for testing. If the test confirmation error exceeds the national standard, it can be debugged. You can contact us if you have difficulties in debugging. We only carry out equipment maintenance and debugging under the supervision of the Technical Supervision Bureau. Will not change the measuring equipment at will at the invitation of people.

The maintenance and transformation of metering equipment should be carried out in strict accordance with the provisions of the national metrology law.
