Study On Some Safety Problems Of The Daye Iron Deep Open-pit-mine Transferring To Underground Mining

Along with our country the end of open pit mining, more and more will turn to mine underground mining, security problems are more and more attention, therefore, The problems which open to the underground mining safety must be in the course of research. The Daye iron mine belongs to this.This article, understanding geological conditions about the Daye iron mine, discusses the security issues to mining area on the basis of open to underground mining and then on the three main issues which the stability of underground roadway, open slope stability and drainage for a more detailed research, provides the actual security program at the scene and resolves the practical problems encountered in the mine with similar reference significance to a certain extent to promote significance.The stability of underground roadway is studied which is the higher shear stress state. The roadway is the main form of the destruction and tablets to help run the roof collapse, and open Daye iron mine mining to underground mining site for the first Displacement Monitoring, identifying 24 m level of existence four potential safety problems, propose governance program to ensure the safety of roadway in the open slope stability study, the East Daye iron mine underground mining open to the -36 m and -48 m level production Blasting the seismic waves generated by the testing, blasting seismic wave reached for open high slope less affected, will not lead to slope instability and came blasting seismic wave propagation law; Finally, this article on open water to underground mining safety the study, the flow of water drawn, and made corresponding security governance programs to avoid a thunderstorm Daye Iron open to the underground mining disaster impact.
