Simulation system model for demonstrating coal mining and roof dynamic changes

Abstract

The invention discloses a simulation system model for demonstrating coal mining and roof dynamic changes. The simulation system model for demonstrating the coal mining and the roof dynamic changes comprises a masonry beam module, an immediate roof module, a first false roof module (6), a coal bed module (7), a baffle (8) and an air bag (9), wherein the masonry beam module is composed of a first masonry beam module (2), a masonry beam body (1) and a second masonry beam module (3); the immediate roof module comprises a first immediate roof module (4) for supporting the first masonry beam module (2), and at least four second immediate roof modules (5); the first false roof module (6) and the coal bed module (7) are used for supporting the first immediate roof module (4); the baffle (8) is used for supporting the rear parts of the second immediate roof modules (5) and is lower than the coal bed module (7); the air bag (9) is placed in a containing cavity formed by the baffle (8), the second immediate roof modules (5) and the coal bed module (7). The simulation system model for demonstrating the coal mining and the roof dynamic changes can dynamically demonstrate the coal mining and the roof structural changes, is easy to manufacture, is high in operability and can demonstrate circularly.

Description

technical field [0001] The invention relates to a comprehensive simulation model of visualized mine pressure appearance in coal mine mining, which is especially suitable for the teaching demonstration of the dynamic change process of the coal seam roof structure in coal mine mining. Background technique [0002] In the teaching, production and scientific research activities of the coal industry, mine pressure manifestation is the core of the research, and the change of the roof structure of the coal seam is an important content of all research. In order to let everyone understand the complex and invisible roof structure changes in the mine, the main The best method is to make a structural static schematic diagram and a structural static model of the roof. However, such methods cannot clarify the process of mine pressure appearance; very few electrical automation models are not only difficult to reproduce the specific change process of the roof, but also expensive and easy to...
