Multi-parameter spatio-temporal evolution analysis experiment table for mine thermal power disasters

Abstract

The invention discloses a multi-parameter spatio-temporal evolution analysis experiment table for mine thermal power disasters, and the experiment table comprises an experiment table device and an experiment control terminal. The experiment table device comprises an experiment skeleton, a pile supporting platform, and a tunnel simulation module. The tunnel simulation module is provided with a switching valve, a fan, and an execution mechanism. The interior of the tunnel simulation module is provided with a disaster detection mechanism, and the disaster detection mechanism comprises a housing and a sensor module disposed on the housing. The housing is provided with an electrode probe group. The tunnel simulation module comprises a simulation main shaft tunnel, a simulation auxiliary shaft tunnel, a simulation mining region tunnel, a main return tunnel, a transportation big tunnel, and a connection tunnel. The execution mechanism comprises a conveying pipe, a smoke generator, a high-pressure air bottle, and a heater. The pile supporting platform comprises a plurality of supporting piles. The experiment control terminal comprises an operation host and a data collector, and the output end of the operation host is connected with a relay and a holder drive module. The experiment table is accurate in simulation of thermal power disasters of the whole mine, and is good in effect of experiment analysis of multi-parameter spatio-temporal evolution.

Description

technical field [0001] The invention belongs to the technical field of mine thermodynamic disaster simulation, and in particular relates to a multi-parameter space-time evolution analysis test platform for mine thermodynamic disasters. 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. At the same time, it also greatly...

Problems solved by technology

In terms of experiments, no dedicated full-scale experimental mine and large-scale physical similar experimental platform have been established, and most of them only study the disaster propagation process in a small area of ​​the mine (such as a single working face, or a small section of roadway). The research on the multi-parameter spatio-temporal evolution of thermodynamic disasters in the
