Abstract: Combined with the test method and current situation of self-rescuer and respirator used in coal mine, the implementation standards and technical requirements of self-rescuer and respirator used in coal mines in China, European Union and the United States are compared and analyzed. The problems in the detection and inspection technology of self-rescuer and respirator used in coal mines in China are pointed out, such as over-long standard age, imperfect technical requirements, inconsistent technical indexes with foreign countries and backward inspection equipment, and some suggestions are given.
