The invention relates to a coal mine dynamic disaster multi-parameter coupling and determining device and relates to the coal mine dynamic disaster determining device. By adopting the coal mine dynamic disaster multi-parameter coupling and determining device, a real coal mine underground dynamic disaster occurrence environment can be simulated, and the surrounding rock stress and gas pressure when the dynamic disaster happens can be accurately measured. Two perpendicular synchronous loading hydraulic cylinders are respectively fixedly connected with the upper surface and the lower surface of a high-pressure-resisting rigid closed shell, and two perpendicular synchronous loading hydraulic cylinder rods are fixedly connected with a pressure block I which is arranged in the high-pressure-resisting rigid closed shell; two horizontal synchronous loading hydraulic cylinder bodies are fixedly connected with the left outer side surface and the right outer side surface of the high-pressure-resisting rigid closed shell, and two horizontal synchronous loading hydraulic cylinder rods are fixedly connected with a pressure block II which is arranged in the high-pressure-resisting rigid closed shell; rodless cavities of the two perpendicular synchronous loading hydraulic cylinder bodies are respectively communicated with cylinder bodies of two small plunger hydraulic cylinders II through two pipelines I, and rodless cavities of the two horizontal synchronous loading hydraulic cylinder bodies are respectively communicated with cylinder bodies of two small plunger hydraulic cylinders II through two pipelines II. The coal mine dynamic disaster multi-parameter coupling and determining device is used for determining dynamic disaster parameters of a coal mine.
Description
technical field [0001] The invention relates to a coal mine dynamic disaster measuring device. Background technique [0002] The formation mechanism of dynamic disasters in deep mining is complex, and there are many inducing factors. Mine dynamic disasters are closely related to the physical and mechanical properties of coal and rock, and are related to factors such as ground temperature, coal seam occurrence and geological structure, and are the result of the joint action of factors such as ground stress and gas pressure. [0003] The existing coal mine dynamic disaster index test device mainly includes a surrounding rock dynamic disaster test device and a coal and gas outburst test device. The surrounding rock dynamic disaster test device mainly uses the rock mechanics test system, and the coal and gas outburst test device is mainly used to test the gas pressure index when the dynamic disaster occurs. The two test devices are independent of each other, and the index para...
