Simulation Study on Pressure Distribution and Support Technolo-gy in Ultra Deep Mine——Taking China Minmetals Chentaigou Iron Mine as an Example
The safe mining of ultra deep mines has always been an important issue in the field of mining engineering.This arti-cle takes the Chentaigou Iron Mine of China as an example and uses simulation technology to study the pressure distribution and support technology of ultra deep mines.By comprehensively analyzing factors such as geological conditions,mining meth-ods,and support structures,a numerical model of ground pressure distribution in ultra deep mines is established,and the pro-cess of ground pressure changes at different mining stages is simulated.Evaluate its effectiveness through simulation.The re-sults show that reasonable selection of support structures and optimization of support parameters can effectively improve the support effect and safety of mines.In addition,in-depth exploration was conducted on the formation mechanism of ground pres-sure in ultra deep mines,providing a theoretical basis for further optimization of support technology.
