Problems solved by technology

At present, many experimental methods at home and abroad cannot simulate the deep Austrian ash water inrush process well. Most researchers conduct research on the basis of numerical models and cannot intuitively obtain test results.
In addition, the combination of graphics, text or audio in teaching practice cannot fully meet the daily teaching tasks
The experimental exploration must not be based on the actual occurrence of t...

Abstract

The invention discloses a multi-field coupling test device and method for simulating deep mining Ordovician limestone water inrush, and mainly relates to the field of coal mine goaf disaster prevention and control. According to the test method, rock stratum models with different proportions or different structures or different distributions are established according to actual geological conditions of a coal mine, various conditions such as deep ground stress, bottom plate water pressure, rock stratum temperature and mining disturbance are simulated through the test device, and various measurement data in the test process are recorded. A deep mining coal seam floor Ordovician ash water inrush phenomenon and a path are generated. The test device is simple in structure, convenient to maintain and accurate in monitoring data, the test method is scientific in principle and easy and convenient to operate, the characteristics and mechanisms of the Ordovician limestone water inrush in deep mining are simulated and analyzed, teaching tasks and test exploration of the Ordovician limestone water inrush mechanism are met, and effective test data are provided for prevention and control of the Ordovician limestone water inrush and safe mining of coal mines.

Description

technical field [0001] The patent of the invention belongs to the field of disaster prevention and control in coal mine goaf, and specifically relates to a multi-field coupling test device and method mainly used for simulating deep mining Austrian ash water inrush. Background technique [0002] Coal resources account for more than 58% of my country's energy structure, which guarantees and affects the development of my country's economy and society. Therefore, the safe and efficient mining and utilization of coal resources is the top priority in my country's economic development, and it also affects my country's national economy and people's livelihood. a daunting task. With the gradual depletion of shallow resources in North China type coalfields in the eastern region, mines have gradually entered the stage of mining deep resources. Compared with shallow mining, deep mining has the characteristics of high stress, high pressure, high ground temperature, and severe disturbance...
