Abstract

The invention relates to a three-dimensional solid-liquid coupling similar simulation system and method used for digging coal seam, belongs to the field of coal mining simulation technology, and solves the problem that the existing three-dimensional solid-liquid coupling similar simulation is complex in operation, high in cost, and bad in reliability of the simulation result. The simulation systemcomprises a box body, a container and a balance; an upper overlying strata, a coal layer and a lower overlying strata are arranged in the box body from top to bottom; the coal layer is made of paraffin; the upper overlying strata and the lower overlying strata are made of rock and soil granular material; a heating device is arranged between the coal layer and the lower overlying strata; a discharge port is arranged on the side wall of the box body; the discharge port is located at the junction of the coal layer and a bottom plate of the coal layer; the discharge port is connected with the container by a conduit; and the container is placed on the balance. The simulation system and method provided by the invention simulate the excavation of the coal layer in the three-dimensional solid-liquid coupling similar simulation test; and the simulation result is more reliable.

Description

technical field [0001] The invention relates to the technical field of coal mine mining simulation, in particular to a coal seam excavation method for three-dimensional solid-liquid coupling similar simulation. Background technique [0002] In order to improve the efficiency and safety of coal mining, three-dimensional solid-liquid coupling similar simulation experiments are often used to simulate coal mining before coal mining. The three-dimensional solid-liquid coupling similar simulation experiment is to lay rock-soil granular materials in proportion in the experimental box, and according to the specific site conditions, simulate the actual stratum structure, simulate the actual mining process and detect and record the first-related parameters. The obtained results have research value. [0003] In the whole simulation process, the link of coal seam excavation is the key point of the whole experiment. At present, there are some methods, such as manually excavating the si...
