Coal mine gas and coal rock gas multi-seam multi-level three-dimensional development model

The invention discloses a coal mine gas and coal rock gas multi-seam multi-level three-dimensional development model, which belongs to the technical field of coal bed gas development simulation, and comprises a model main body, the top of the model main body is provided with a first horizontal well, a second horizontal well, a vertical well and a goaf negative pressure extraction well, the model body comprises a surface layer, and a plurality of shale gas layers, tight gas layers and coal bed gas layers are fixedly arranged at the bottom of the surface layer. According to the invention, through various designed well production conditions, when the current resource is exhausted or the predicted coal bed gas resource production amount is far less than the use requirement, the simulation display for improving the production efficiency can be realized, the deadly damage to the coal quality of the produced coal and the management of the top and bottom plates cannot be caused, and the production efficiency of the c
