Research on Automatic Cross Section Cutting and Forming Control in Coal Mine Underground Based on Oil Cylinder Stroke Sensor and PCC Electrical Control System


This paper proposed a automatic cross section cutting and forming control method based on oil cylinder stroke sensor and PCC electrical control system to fulfill the automatic cutting of roadway section in coal mine underground. High precision oil cylinder stroke sensor was used to improve control precision; optimizing cutting processing route of automatic cross section forming to raise the cutting efficiency; the concept of section profile was proposed to control cutting head cutting within the section profile which will be used to achieve the function of arbitrary cross section cutting. The above control method has been verified correct and practicable on PCC electrical control system.
