Research on precise acquisition and analysis technology of hydraulic support resistance in fully mechanized mining face
Traditional hydraulic support resistance acquisition instrument adopts a single sampling mode with equal time intervals.Due to the short time consumption of the relocation process of hydraulic supports,it is difficult to obtain complete resistance data of the supports,resulting in sampling missing of key sampling points such as cycle initial support force and cycle final resistance,inaccurate basic analysis data,excessive redundant data,and high power consumption of collection equipment,which in turn affects the accuracy of the mine pressure analysis results.To address this issue,a multi-modal support resistance precise acquisition method and instrument design combining dynamic high-speed with static low-speed were proposed,and the multi-modal analysis method and software design for hydraulic support resistance were elaborated in detail.Experiments and engineering applications had shown that the monitoring system of the new multi-modal acquisition and analysis method could improve the accuracy of support resistance monitoring data,reduce the power consumption of the acquisition instrument,and minimize the redundant data,thereby making the support resistance analysis results more accurate.
