Geological Disaster Prevention And The Disposal Of Caved Stope In DongPing Gold Mine

After affirming industrial value of the DongPing gold mine, the government of ChongLi deceided to build mine selection factory that can deal with 50 tons of ore per day in June of 1986.DongPing Gold mine have six caved area, among them the first mining area and south mountain production mining area are central production mining area. They were all exploited now. South mountain production mining area had formed 21 caved area and it's volume reachs 267770 m~3.The first production mining area had formed 8 caved area and it's volume reachs 52414m~3. The existence of these caved area may produce serious dangers. Therefore, the further study to the form, process and harm of the caved area's collapse should be carried out.Synthetical caved area disposal range of DongPing gold mine includes caved area formed by 1464 segment to 1375 segment of the first mining area and south mountain mining area.In this thesis,through the detailed investigation to the spot geological circumstance , caved generalization and the spot caved area's shape,the caved area and correlative information are described. On the base of analysis of character ,rules and parameters,the form and scale of the DongPing gold mine's caved area's cllapse are ascertained and the velocity of air wave from the caved area's collapse is reckoned.Using FLAC numerical simulation software,this thesis analyzes deformation , break course and stability of DongPing gold mine.Eventually combining existing treatment methods and characteristic of DongPing gold mine's caved area,we ascertain measures of DongPing gold mine's caved area. Using FLAC software on the numerical simulation examination not merely have a strong , convenient flexible and repeatable characteristic of commonability, but also can get a lot of important information that...
