Research on Optimization Design of Working Face Support System for Excavating and Anchoring Integrated Machine
To further improve the construction efficiency of the excavating and anchoring integrated machine,according to the existing support materials and methods of the excavation working face in Wenjiapo Coal Mine,the pre tension force of the anchor rod during the support process is modified to enhance the design strength of the support.The layout ways of the roof anchor rod and anchor cable support in the roadway are optimized,and the side walls of the roadway are designed with segmented support.The optimized roadway support pressure is calculated using the universal pressure arch theory,and the results show that the safety factors of each roadway in the designed support scheme are greater than 3.The optimized scheme can give full play to the performance of anchor cable materials,and improve the safety and reliability of the support links and the efficiency of excavation and support while ensuring the safety of the working face.
