The system is used to monitor the environmental gases and the status parameters of electromechanical equipment underground. When an event occurs, it generates alarms, power cuts, controls, etc., and forms various reports. Based on the requirements of the new coal mine safety regulations, electronic gas inspection boards and related equipment are added to achieve less personnel demand for underground gas inspection. At the same time, equipment such as on-board methane power cut-off instruments are added to provide a solution for uploading methane data from underground coal miners.
