Intelligent transformation of Nanhu 7#Coal Mine's truck loading system

Abstract：In making intelligent transformation of the truck loading system traditionally used at a coal mine,lots of difficulties in transformation of loading process,selection of equipment and cost control are generally met with.The intelligent transformation of the traditional bunker system for loadout at Nahu7#Mine is taken as ob-ject for case study.Based on analysis of the specific conditions of the system before transformation,a process optimization-intelligent transformation integrated strategy is proposed.For process optimization,a new loaded coal metering method is used,which integrates three measuring technologies of radar modeling,weighing by weighbridge and constant-tonnage feeder,and is capable of carrying out interactive communication.With re-spect of intelligent transformation,four subsystems for respectively dealing with queue calling-up,unattended weighing of loaded coal,automatic truck loading and centralized control operations.Practice shows that the effi-ciency for loading a truck going through the renovated weighbridge has seen a rise by about 70%;the phenom-ena of underloading,overloading and nonuniformly distributed loading are practically eliminated;the goals of turning the mine's loading system to an intelligent and unattended one has achieved;and the cost-effective trans-formation work has brought about remarked economic result and improved loading efficiency.The successful execution of the project may serve as a reference for making similar renovation work by other mines.
