Abstract

The invention discloses an experimental method based on a thermo-motive disaster multi-parameter spatio-temporal evolution analysis experiment table. The method comprises the steps of 1, determining a mine simulation object and establishing an experiment table device; 2, detecting the airtightness of the experiment table device; 3, initializing an experiment control terminal; 4, controlling the change of ventilation quantity in a roadway simulation module, roof caving position, roof caving degree and smoke and gas discharge position and speed, and acquiring the mine thermo-motive disaster multi-parameter spatio-temporal evolution process; 5, judging whether the concentration of gas and oxygen in the roadway simulation module reaches a critical threshold value causing gas explosion; 6, triggering secondary gas explosion in the roadway simulation module and analyzing thermo-motive disaster multi-parameter spatio-temporal change. Steps are simple, mine roadway ventilation quantity, roof caving phenomenon and the change of smoke and gas generating rates of different positions can be simulated, the position where secondary gas explosion occurs easily in the roadway simulation module can be acquired, and thermo-motive disaster multi-parameter spatio-temporal change can be analyzed.

Description

technical field [0001] The invention belongs to the technical field of mine thermodynamic disaster simulation, and in particular relates to an experimental method based on a thermodynamic disaster multi-parameter spatio-temporal evolution analysis experiment platform. Background technique [0002] The occurrence and evolution mechanism of thermal dynamic disasters in coal mines is extremely complex, with the characteristics of strong suddenness, rapid development of disasters, huge casualties and property losses, difficulties in disaster relief, and easy to cause secondary injuries. During the rescue process, a variety of secondary disasters may occur underground in coal mines. For example, the high-temperature open flames generated by the disaster may block the route for rescuers to enter and exit the disaster area at any time, and cause the ventilation disorder in the disaster area, making the environment in the disaster area extremely unstable. A gas explosion occurred. ...
