Gas outburst simulation test system capable of monitoring stress, temperature and gas pressure

The invention discloses a gas outburst simulation test system capable of monitoring stress, temperature and gas pressure, which comprises a main body model and a post-outburst solid gas treatment device, and is characterized in that three compacted raw coal powder layers are laid in a test piece box module at intervals up and down; a gas pressure sensor group, a stress sensor group and a temperature sensor group are sequentially arranged in the test piece box module at equal intervals from left to right, the arrangement number and position of each group of sensors are consistent, each group of sensors comprises eight sensors which are arranged in a coplanar manner, and the sensors are annularly and equidistantly divided into four rings by taking the X-direction central axis of the test piece box module as a circle center; the first ring and the third ring are respectively provided with two sensors located at the left vertex and the upper vertex, and the second ring and the fourth ring are respectively provide
