Device for measuring spontaneous combustion dangerous area of coal mine underground roof-cutting entry retaining goaf

The utility model discloses a device for measuring a spontaneous combustion dangerous area of a goaf of an underground coal mine roof-cutting entry retaining. Comprising a roof-cutting entry retaining side temperature and gas collector, an air return side goaf temperature and gas collector, a mining anti-explosion automatic high-negative-pressure sucking pump, a temperature monitoring module, a beam tube monitoring module, a remote transmission cable and a ground data receiving device, a roof-cutting entry-retaining side thermistor probe and a roof-cutting entry-retaining side gas collector are assembled in the roof-cutting entry-retaining side temperature and gas collector, and an air return side temperature monitoring probe and an air return side gas collector are assembled in the air return side goaf temperature and gas collector. According to the utility model, multiple composite natural ignition landmark indexes such as temperature, O2 concentration, CO concentration, C2H4 concentration and the like of t
