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 important energy source in China, along with the depletion of eastern coal resources, western coal yield is larger and larger in the total coal yield ratio, and western regions also have a large amount of coal resource reserves, but western regions are severely lack of water, domestic expert students take Shendong mining areas as bases to develop series of research works, aiming at the typical type ecological environment and coal exploitation process characteristics of western regions in China, the conversion rule of 'three water' (surface water, soil water and underground water) is revealed, but the method cannot be effectively implemented on a large scale due to the factors such as environment, time period and the like; secondly, aiming at the characteristics of the ecological environment of the mining subsidence area of the western typical type, the research on the theory of 'loss reduction' of coal mining and the key control technology is difficult to find and monitor the working faces with different mining parameters under the same or similar geological production conditions in reality for comparison; aiming at the defects of the research work, a large-scale simulation test platform needs to be built indoors on the basis of combining coal exploitation and on-site monitoring.
However, in the existing mining simulation technology, for the laying of the aquifer, the aquifer is simulated by using water in bags, namely: other simulated rock formations are paved from bottom to top, water is filled in a water bag when an aquifer is paved, and then the simulated rock formations are paved on the water bag continuously. Whereas the water level dynamic monitoring method is not seen in the mining physical simulation.
The water bag is used for simulating the aquifer, after the water bag is sealed, water cannot flow out, and the water level change of the aquifer cannot be simulated. In addition, the water bag is far from the physical and mechanical properties of the water-resisting layer, and the water bag can not simulate the mechanical properties of the water-resisting layer; the water bag simulation aquifer cannot simulate the water level change of water in the aquifer after the water is influenced by mining; the water bag cannot simulate how water in the aquifer reaches the mining face through the crack after being disturbed by mining.
Another model laying method is used when simulating loose aquifers, namely: firstly, other simulated rock formations are paved from bottom to top, when an aquifer is paved, a seepage pipeline with micropores is paved, the simulated rock formations are continuously paved on the pipeline, after all the rock formations are paved, water is injected into the reserved pipeline, and water flows out through the micropores, so that the aquifer is simulated.
However, the method used in the simulation of the loose aquifer can only simulate the loose aquifer, but not simulate aquifers in other states, and does not simulate a water-resisting layer, but only can perform seepage experiments and cannot perform other simulation experiments.
Therefore, the existing mining simulation technology cannot simulate the influence of mining on the aquifer on large-scale simulation experiment equipment, and cannot monitor the change of the water level in the aquifer, and the flow direction of water after the aquifer is destroyed.

Specifically, the experimental method of the mining three-dimensional simulation experiment model comprises an aquifer laying method and a simulated aquifer water level dynamic monitoring method in a three-dimensional simulation experiment.
Wherein, step S201 to step S202 finish the aquifer laying in the three-dimensional simulation test. The water-proof layer is necessarily laid in the water-bearing layer, so that the water-proof layer and the water-bearing layer laying method form a first majority together.
When the simulated water-resisting layer is paved, the simulated material similar to the actual water-resisting layer is smeared with the waterproof paint, the smearing quantity of the waterproof paint depends on the permeability of the water-resisting layer to be simulated, and an experimenter can change the smearing quantity of the waterproof paint to change the permeability of the simulated water-resisting layer;
Taking ice cubes as simulated aquifer materials, the ice cubes are directly paved when the aquifer is paved, other simulated rock strata are paved on the ice cubes, the aquifer is arranged after the ice cubes are melted, the paved ice cubes can be pure water or can contain other simulated materials (the water and the other materials can be frozen together to contain the other materials or can be respectively ice cubes and the other simulated materials), and pipelines which directly reach the ground surface can be reserved when the aquifer is paved for simulating a water supplementing path or can not be reserved, so that the experiment personnel can select the process by themselves.

Step S203 and step S204 dynamically monitor the simulated aquifer water level.
The dynamic water level detecting method consists of two parts, one part is used for monitoring the water level and the other part is used for monitoring the flowing direction of water.
The method of paving the pressure device at the bottom of the ice blocks is adopted for monitoring the water level, when the mining behavior damages the aquifer, water flows out along the water, and the pressure device at the bottom of the water changes the indication, so that the water level change condition is known.
Monitoring the water flow direction is to lay bare conductive wires in a simulated formation with the lower part of the aquifer. The conductive metal wires are preferably copper wires, and the copper wires are preferably laid at intervals of a preset distance to form a copper wire network space. The simulation experiment can not be influenced by the copper wires laid every 5 cm, the electrified conductive metal wire is provided with a resistor, the resistor can be changed after the electrified conductive metal wire is contacted with water, a fracture zone can be generated when mining is performed, if a water-resisting layer is damaged by the fracture zone, water in the water-bearing layer flows along the fracture, the resistor of the electrified conductive metal wire can be changed when the water flows to the position where the conductive metal wire is laid, and whether the water penetrates through the water-bearing layer is measured according to the change of the resistor. Finally, dye can be added into the ice cubes, and the flowing position is dyed when water flows along the cracks, so that a simulated rock stratum can be excavated after the experiment is finished, and the flow direction of the water is observed.
The experimental method of the mining three-dimensional simulation experiment model of the embodiment comprises a method for paving an aquifer and dynamically monitoring the water level in the three-dimensional simulation experiment, and is used for simulating the influence of mining behaviors on the aquifer. The simulated aquifer laying method comprises a simulated aquifer laying method and a simulated aquifer laying method, and the water level dynamic monitoring method comprises a water level monitoring method and a water flow dynamic monitoring method.
The simulation water-resisting layer laying method realizes the simulation of the water-resisting layer by the method of coating the simulation material with the waterproof coating, thereby achieving the purpose of simulating the influence of mining on the water-bearing layer on large-scale simulation experiment equipment. The simulated aquifer laying method avoids the difficulty of laying materials on water by laying ice blocks on the simulated waterproof layer coated with the waterproof material and continuing to lay other simulated materials on the ice blocks. The dynamic water level monitoring method realizes the monitoring of the water level by paving bare conductive metal wires, thereby achieving the purpose of knowing the water level change in real time. The method for monitoring the water flow dynamics realizes the monitoring of the water flow dynamics by adding dye into ice cubes, thereby achieving the purpose of defining the water flow dynamics after the water-bearing layer is destroyed.

step S405, if the simulated water-resisting layer is a simulated rock stratum, executing step S402, otherwise executing step S406;
step S406, paving a simulated aquifer, which specifically comprises the following steps:

The metal wires can be reserved in the ice cubes, and the ice cubes can be quickly melted by electrifying and heating the metal wires, and the ice cubes can be naturally melted;
step S407, if there is a simulated aquifer above the simulated aquifer, executing step S404, otherwise paving the simulated earth formation 6 on the simulated aquifer 5.
FIG. 5 is a flow chart of the water level dynamic monitoring operation of the experimental method of the mining three-dimensional simulation experimental model according to the preferred embodiment of the invention, which comprises the following steps:
Step S501, a rock stratum simulation device paved by adopting a mining three-dimensional simulation experiment model paving method, namely a mining three-dimensional simulation experiment model;
step S502, monitoring the water level of the rock stratum simulation device;

step S504, after the experiment is finished, digging and observing, specifically:
After the simulation experiment is finished, the model is excavated, and the detailed position of water flowing through is observed. Since the dye is present in the water, the location where the water flows is dyed by the pigment, and the dyed portion of the model is observed, whereby the detailed water flow path is known.
When the simulated water-resisting layer is paved, a simulation material similar to the actual water-resisting layer is smeared with the waterproof coating, so that the physical and mechanical properties of the actual water-resisting layer can be simulated, while the water bag simulates the water-resisting layer method, the physical and mechanical properties of the water bag and the water-resisting layer are far different, and the water bag can not simulate the mechanical properties of the water-resisting layer;
The ice blocks are directly paved when the aquifer is paved, the ice blocks play a supporting role, a special supporting structure is not needed, the ice blocks are not melted when other simulated rock layers are continuously paved, the other rock layers can be directly paved on the ice blocks, after all the simulated rock layers are paved, the ice blocks are melted to form the aquifer, the pure water ice blocks and the simulated water-resisting layers are paved to simulate the confined water aquifer together, the ice blocks containing other simulated materials are fine sand and the like, and the aquifer in other forms can be simulated, so that the method belongs to an initial method, and is simple and practical, and extremely high in simulation reality;
the above descriptions together form an aquifer laying method which overcomes the disadvantages that the water bag cannot be broken and water cannot flow out of the water bag; the defect that the simulated aquifer can not simulate the water level change of the real aquifer after the water bag is filled with water and the water in the real aquifer is influenced by mining is overcome;
Aiming at the characteristic that the water level of the aquifer can change after mining influences the aquifer and water flows out along cracks, the method initiates a water level dynamic observation method in a mining simulation experiment, can measure the water level of the aquifer in the simulation experiment in real time, can also know the water level change in a non-transparent rock simulation material, and can know whether mining behaviors influence the aquifer or not through the water level change.
