Embodiment Construction
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0022] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication also changes accordingly.
[0023] Such as figure 1 , t...

A coal and gas outburst test device and method with a supply gas source, the test device includes a coal sample tank, one side of the coal sample tank is connected with a gas supply bag, the gas supply bag is connected to an air compressor, and the coal sample tank There is an opening on the other side, a tempered glass plate is arranged on the inside of the opening, a pipe is arranged on the outside of the opening, and a firing device is arranged outside the pipe. One end of the firing device is fixed on the outside of the pipe, and the other end is provided with a firing hammer. Attached to the toughened glass plate, there are multiple pressure sensors and multiple photoelectric sensors at intervals on the inner wall of the pipeline, and a light source is installed outside the pipeline corresponding to the position of each photoelectric sensor, and a transparent panel is provided between the light source and the photoelectric sensor for the light to pass through . The gas supply bag continuously supplies gas to the coal sample tank to more realistically simulate the occurrence of coal and gas outburst disasters. The pressure sensor can measure the gas pressure in the pipeline and reflect the migration status of the outburst gas in the pipeline. The photoelectric sensor and light source can The migration position of the outburst coal flow is measured.
Description
technical field [0001] The invention relates to a coal and gas outburst test device, in particular to a coal and gas outburst test device and method with a gas supply source. Background technique [0002] Coal and gas outburst refers to the unsteady coal and rock mass in the coal mine suddenly ejecting a large amount of coal and gas to the space of the mining face, destroying the roadway and facilities, destroying the ventilation system, and the shaft is full of gas, coal and powder, causing burial or suffocation, serious Threatening the safe production of coal mines. In recent years, the death toll due to coal and gas outburst accidents in mines has accounted for about one-third of the total death toll in coal mine gas disasters. Carry out research on prevention and control technology in order to provide a scientific basis for the formulation and implementation of risk prediction and outburst prevention measures. There are few studies on the disaster evolution process of ...
