Description
Technical Field
The invention relates to the technical field of coal mine correlation, in particular to a mining three-dimensional simulation experiment model experiment method.
Background
Coal is the most main energy in China, with the exhaustion of the east coal resources, the west coal yield is increasingly larger in the total coal yield proportion, and the west region also has a large amount of coal resource reserves, but the west region is seriously lack of water, domestic experts and scholars develop a series of research works by taking the Shendong mining area as a base, disclose the transformation rule of 'three waters' (surface water, soil water and underground water) aiming at the typical type ecological environment and the coal mining process characteristics of the west region in China, but cannot be effectively implemented on site in large scale due to factors such as environment, time period and the like; secondly, aiming at the ecological environment characteristics of a western typical type coal mining subsidence area, the research on the coal mining loss reduction theory and the control key technology is difficult to find and monitor the working faces with different mining parameters under the same or similar geological production conditions in reality; aiming at the defects of the research work, a large simulation test platform needs to be built indoors on the basis of combining coal mining and field monitoring.
However, the existing mining simulation technology for laying the aquifer simulates the aquifer by using water filled with water, namely: laying other simulated rock stratums from bottom to top, filling water by using a water bag when laying a water-bearing stratum, and then continuously laying the simulated rock stratums on the water bag. And a water level dynamic monitoring method is not seen in the physical simulation of mining.
The water bag is used for filling water to simulate the aquifer, and after the water bag is sealed, the water cannot flow out, so that the water level change of the aquifer cannot be simulated. In addition, the physical and mechanical properties of the water bag and the water-resisting layer are far different, and the water bag cannot simulate the mechanical properties of the water-resisting layer; the water bag simulates the aquifer and cannot simulate the water level change of the water in the aquifer after the water is influenced by mining; the water bag can not simulate how the water in the aquifer reaches the mining working face through the fissure zone after being disturbed by mining.
Another model laying method is used when simulating a loose aquifer, namely: lay other simulation rock formations from supreme down earlier, when laying the aquifer, lay the seepage flow pipeline of taking the micropore, continue to lay the simulation rock formation on the pipeline, after having laid all rock formations, to reserving the pipeline water injection, water flows out through the micropore to this simulation aquifer.
However, the method used for simulating the loose aquifer can only simulate the loose aquifer, cannot simulate the aquifer in other states, does not simulate the water barrier, can only perform seepage experiments, and cannot perform other simulation experiments.
Therefore, the influence of mining on the aquifer cannot be simulated by the existing mining simulation technology on large-scale simulation experiment equipment, the change of the water level in the aquifer cannot be monitored, and the flow direction of water after the aquifer is damaged is prevented.

Wherein, the step S201 to the step S202 finish the laying of the aquifer in the three-dimensional simulation test. The method of laying a water barrier and the method of laying a water barrier together form the first major part, since the water barrier must not be laid when laying an aquifer.
When the simulated water-resisting layer is laid, a simulation material with the property similar to that of the actual water-resisting layer is coated with the waterproof paint, the coating amount of the waterproof paint depends on the permeability of the water-resisting layer to be simulated, and an experimenter can change the coating amount of the waterproof paint to change the permeability of the simulated water-resisting layer;

The water flow direction is monitored by laying bare conductive wires in the simulated rock formation below the aquifer. The conductive metal wires are preferably copper wires, and preferably the copper wires are laid at intervals of a preset distance to form a copper wire network space.

The simulated aquifer laying method avoids the difficulty of laying materials on water by laying ice blocks on the simulated water-resisting layer coated with the waterproof material and continuously laying other simulated materials on the ice blocks. The water level dynamic monitoring method realizes the monitoring of the water level by a method of laying exposed conductive metal wires, thereby achieving the purpose of knowing the water level change in real time. The water flow dynamic monitoring method realizes the monitoring of the water flow dynamic by adding the dye into the ice block, thereby achieving the purpose of determining the water flow dynamic after the aquifer is damaged.
Fig. 4 is a working flow chart of the laying work of the mining three-dimensional simulation experiment model experiment method according to the preferred embodiment of the invention, and fig. 3 is taken as an example to illustrate specific steps, which include:
