Abstract
Description
technical field
[0001] The invention relates to an early warning monitoring method for ground pressure safety in soft rock roadways of underground mines, and belongs to the technical field of ultrasonic flaw detection methods for heavy rails. Background technique
[0002] The appearance of ground pressure is the deformation, cracking, breaking, chipping, collapse and roof fall of the surrounding rock mass and support structure caused by the formation pressure acting on the mining tunnel and stope. It is one of the main reasons for the difficulty of mining underground deposits. . Many domestic mines suffer from this, such as Zhangjiawa Iron Mine, Shouyun Iron Mine, Xiaoguanzhuang Iron Mine, Xishimen Iron Mine, Yushiwa Iron Mine, Chengchao Iron Mine, Jinshandian Iron Mine, Maoyuan Iron Mine, Jinchuan Nickel Mine A large number of mines, such as Tonghua Jien Nickel Mine, Fanshan Phosphate Mine, Kaiyang Phosphate Mine, Jiaojia Gold Mine, Jinfeng Gold Mine, Fengshan Copper Mine,...
