The Ore Mining Technique Study Of Panel Mechanization Cut-and-Fill Stoping Method Used In Deep Mining Of Tonglushan Mine

Under the premise that ensure the mine production safety and environmental protection,how to improve stoping intensity and efficiency, reduce mining ore loss and dilution in every stage,and ultimately increase the economic efficiency of mine enterprises,that is the main purpose of the mining method and stoping process.This article combine the demand of Tonglushan mine deep mining with the existing problems of the stoping work, and improve the stoping technology of panel mechanized layered filling method. From the blasting parameters determined, the stratification height of stoping chosed, the mine ventilation designed, equipment configuration and ground pressure monitored, the article exposes the theoretical innovation process of the stoping technology, which can provide reference for the practical application.According to the condition and equipments of Tonglu mountain ,adopted the high mark layer and continuous stoping in the deep department of Tonglu mountain ,raised the lower layer while makeing use of the panel mechanized layered filling methodbefore,and changed the original order of stoping.To put 4 mining for a group,and each the first three mineral piece of mining changed 2 steps to one step or the quasi- one step, but only the last mineral piece was still 2 steps.All of that maked the order of stoping to form "pin" in the space.To Enhance the production ability and minerals strength of mining validly,and decrease minerals loss and impoverishment of ore.Meanwhile,to optimize the original mineral equipments,and make it more effectively produce result on the original foundation.Furthermore, combined the mineral characteristic of Tonglu mountain rock,and promoted the technique of Medium-leghth hole blasting.To adopt the more excellent parameter.The practice descripting, this article offered the stoping technology of panel mechanized layered filling method which could raise mineral using rate and ore grade.The economic performance is obvious. Provided the theory form for the deep department of Tonglu mountain.
