Position and Posture Detection Technology of Hydraulic Support in Fully-mechanized Mining Face in Coal Mine
The intelligent cooperation technology of fully-mechanized mining face in coal mine urgently needs to solve the cooperative control problems of shearer precise positioning and adaptive operation,automatic straightening of scraper conveyor,automatic following of hydraulic support and other systems based on complex underground conditions.The position and posture detection technology of hydraulic support is one of the key technologies to realize intelligent cooperation.A posture detection scheme of hydraulic support based on multi-dimensional sensing was proposed,which can obtain the absolute position and posture of hydraulic support in absolute coordinate system by means of reference photoelectric tracker,local photoelectric tracker,biaxis level meter and other devices,laying a foundation for more accurate realization of fully-mechanized mining face geographic information system and correction,straightening and control of hydraulic support.The scheme has been tested at the fully-mechanized mining face.The operation results showed that it effectively realized the accurate detection of the absolute position of the hydraulic support at the fully-mechanized mining face,and the collaborative accuracy and efficiency of the fully-mechanized mining face system was significantly improved.
