On April 9, 2018, the mPower MP100 series products obtained China Coal Safety Certification. Coal safety certification is the abbreviation of coal mine safety certification. In the safety technology system of China’s “Interim Measures for Safety Signs of Coal Mine Products”, the certification of mining equipment should be an important part of ensuring coal mine safety. People have come to realize the benefits of certification of mining equipment for coal mines. The State Economic and Trade Commission and the Coal Mine Safety Supervision Bureau issued the Interim Measures for the Administration of Safety Marks for Coal Mine Products and the Catalogue of Coal Mine Products for the Management of Safety Signs. These documents further clarify the safety mark management agency, determine the scope of product management and the specific rules for the management of safety signs, and are a more comprehensive method of safety sign management. The above measures ensure the safe use of the equipment downhole.
