An Intelligent Temporary While-Boring Support Technology For Raise Boring Method

Ensuring the stability of shaft structure is one key technologies for application raise boring method. In process reaming through rock formations with water disintegration characteristics, impact gushing and drenching may induce partial collapse. To solve this problem, an intelligent temporary while-boring support technology proposed in paper. Firstly, main characteristics are introduced. Utilizing space inside pipes, material conveying pipes nozzle can reach lower part reamer to realize spraying support. Secondly, a composite cementitious supporting good mechanical properties developed ensure sealing waterproofing surrounding rock. Thirdly, test study was carried out on parameters. The results show that best engineering economic benefits under condition rotation speed 2r/min distance between 1m. Fourthly, image classification algorithm based Resnet-34 convolutional neural network proposed, which realizes judgment effect Finally, industrial Lijiahao Coal Mine. paper has performance, effectively achieving resistance rock, not been damaged.
