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 will also change accordingly.

The invention discloses a coal and gas outburst testing device with a supplemental gas source and a method. The testing device comprises a coal sample tank, wherein one side of the coal sample tank is connected with a gas supplementing bag, the gas supplementing bag is connected to an air compressor, an opening is formed in the other side of the coal sample tank, a tempered glass plate is arranged on the inner side of the opening, and a pipeline is arranged on the outer side of the opening; a striking unit is arranged outside the pipeline, one end of the striking unit is fixed to the outer side of the pipeline, and a striking hammer is arranged at the other end and attached to the tempered glass plate; a plurality of pressure sensors and a plurality of photoelectric sensors are arranged at intervals on the inner wall of the pipeline, a light source is arranged in a position, corresponding to each photoelectric sensor, outside the pipeline, and a transparent panel is arranged between the light sources and the photoelectric sensors to allow the light sources to penetrate. Gas is continuously supplemented into the coal sample tank by the gas supplementing bag, the coal and gas outburst disaster occurring process is more truly simulated, pressure of gas in the pipeline can be measured by the pressure sensor, the moving state of outburst gas in the pipeline is reflected, and the moving position of outburst coal flow can be measured by the photoelectric sensors and the light sources.
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 ...
