Abstract:
The roadway in coal mine is prone to deformation of the surrounding rock under the influence of complex disturbance, which induces the imbalance of support attitude matching between roadway surrounding rock and advanced coupling support equipment, breaks the mechanical balance of the original coupling support system, and causes safety accidents. The postures and offsets of the various working spaces of the advanced hydraulic supports under the influence of complex disturbances are systematically analyzed. The D-H parameter matrix transformation method is used to establish the spatial posture kinematic model of a single/group of advanced hydraulic supports. The posture parameters of each key node are obtained through global coordinate transformation. Based on the comparison of the working attitude parameters of the support obtained through simulation analysis and model calculation, the average absolute error of the support height calculation results of the single group of advanced hydraulic support attitude model is 3.92 mm, and that of the coordinate calculation results of the advanced hydraulic support group is (3.26 mm, 1.99 mm), which meet the accuracy requirements of the advanced hydraulic support attitude monitoring. Finally, the spatial attitude kinematic model of a single/group of advanced hydraulic supports is verified and analyzed by using the advanced hydraulic support attitude monitoring test bench. The maximum error value of the experimental results is 4.9 mm, which verifies the accuracy of the established spatial attitude kinematic model of the advanced hydraulic support. The research results can provide theoretical and technical support for the intelligentization of the advanced coupling support system and the safe and efficient mining of coal mine.
