Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0020] figure 1 Shown is a three-dimensional schematic diagram of a flow field simulation experiment platform for coal spontaneous combustion environment in a coal mine goaf according to the present invention. The test bench includes a simulated gob box 24, a simulated ventilation system, a gas release system, a temperature monitoring system and a data acquisition system.
[0021] The simulated goaf box 24 is composed of a simulated goaf and a simulated coal mining face 5 .
[0022] The simulated coal mining face is composed of a simulated coal mining face and a simulated supporting roof, the simulated coal mining face is located at the bottom of one end face of the simulated goaf box, and the simulated supporting roof is located above the simulated coal mining face.
[0023] In the simulated mined-out area box, sand and gravel isolation bel...
