Abstract:

Applying the existing venues as well as facilities，by reasonable planning，construction scheme and optimization of construction sequence，the original horizontal filling station was optimized to be the type of vertical filling station.With this improvement and modification，various issues and disadvantages such as the outdated equipment of original filling station，backward technology，no guarantee for the quality of the filling pulp as well as mining-filling imbalance were solved.After modification of the filling system optimization， the achieved significant results are summarized as follows：（1）a new filling station presented advantage of big sand reserves，good mud making effect，thus gold production capacity was greatly improved；（2）the optimized system was a high degree of automation，simple operation and less laborious；（3）the new system also showed running stability，controllable operation，accurate static and dynamic measurement，stable slurry concentration； （4）the cost of filling was significantly reduced and economic efficiency of enterprises was improved.Practice operation demonstrated that the filling system needs less investment with good benefits.Therefore，it provides a valuable reference and experience for similar mines.
