The invention discloses a gas wireless detecting device for coal mine safe mining, and relates to the technical field of wireless detecting. The gas wireless detecting device comprises a wireless detecting device body shell and a remote terminal. A temperature and humidity sensor, a gas concentration sensor, a safety alarm unit and an illumination unit are fixedly installed on the outer surface ofthe bottom of the wireless detecting device body shell. A central processing unit is arranged in the wireless detecting device body shell. The interior of a mine is monitored in real time through thetemperature and humidity sensor and the gas concentration sensor, a wireless transmitting unit and a wireless receiving unit are wirelessly connected with the remote terminal so that remote real-timemonitoring can be realized, the gas wireless detecting device has a real-time alarm function in the mine, when the gas value abnormally approaches the dangerous range, a remote terminal operator canrapidly make a response and meanwhile the safety alarm unit gives an alarm to personnel in the mine, and the coal mine safety is ensured in two directions.
