Abstract

The invention relates to the technical field of simulation of coal mining under phreatic water and piestic water, in particular to a coal mining simulation experiment device. The coal mining simulation experiment device comprises a casing, wherein the casing is hollow and is provided with an opening in one end, and a coal seam simulation layer is arranged in the casing; an opening-closing mechanism is arranged on the casing and used for opening and closing the casing to expose the coal seam simulation layer; an aquifer simulation layer is arranged on the coal seam simulation layer and communicated with the opening in the upper end of the casing. According to the coal mining simulation experiment device, the aquifer simulation layer is arranged on the coal seam simulation layer, and the opening-closing mechanism is arranged in the position, corresponding to the coal seam simulation layer, of the casing. An experimenter starts the opening-closing mechanism, and coal mining is performed on the coal seam simulation layer, so that the coal mining in the actual situation is simulated, the structure is consistent with the coal mining in the actual situation, further, the experiment device has the function of specific coal mining dynamic demonstration, and accordingly, the aquifer change data measured by the coal mining simulation experiment device are more accurate.

Description

technical field [0001] The invention relates to the technical field of diving and pressurized underwater coal mining simulation, in particular to a coal mining simulation experiment device. Background technique [0002] With the continuous development of my country's economy, the demand for coal in industry is increasing. Then there was a lot of coal mining phenomenon. However, coal mining is often accompanied by threats of disasters such as water, fire, and gas. Therefore, it is particularly important to simulate experiments before coal mining. [0003] The simulation experiment device in the prior art includes a sand container, a water inlet height control device, a water supply device, and a pressure measurement and observation device. The sand container is placed obliquely, and one end of the sand container is provided with a first water inlet pipe. There are several pressure measuring nozzles evenly distributed on the side wall and the bottom surface. The pressure mea...
