Research and Practice on Recovery Method of Deposit Ore in Caving Method to Filling Method
In the process of non-pillar sublevel caving method in Longqiao Iron Mine,there are a large number of ore resources in the original stope,which mainly include overburden layer and footer trian-gle pillar.In order to recover this part of resources safely and effectively,the reasonable recovery principle is determined by analyzing the distribution and technical conditions of the ore in the goaf and the hole,and the recovery plan is put forward.The whole process of mine ore recovery is carried out based on the stability and monitoring of the goaf,and is implemented smoothly,which fully solves the problem of resource loss left by the caving method to fill mining method,extends the mine service life,and can safely deal with the goaf.
