Shanxi Zhongde Dingli Tunneling is widely applied

Shanxi China-German Unity Excavation Equipment Co., Ltd. specializes in underground mining, railway, highway, and hydraulic engineering tunneling projects. Tunneling equipment is categorized into cyclic and continuous excavation machines based on the excavation technique. Cyclic excavation machines complete tunneling through a series of processes including drilling, blasting, muck removal, and support, which are repeated. Different machinery is used for each process.

Drilling applications include trenching drills and drilling vehicles; blasting involves charging devices and charging vehicles; excavation uses bucket loaders, crab claw loaders, clamshell loaders, ripper loaders, scraper loaders, vibratory loaders, and underground loaders, as well as box-type haulers and storage bin vibratory haulers. Support methods include stone prying machines, shed construction machines, bolt drilling and charging vehicles, anchor rope drilling and charging vehicles, concrete spray machines, concrete irrigation machines, rotary jet grouting machines, and pipeline laying machines. Continuous tunneling machinery can simultaneously perform rock breaking, excavation, and support operations, creating tunnels through continuous drilling, known as horizontal tunnel drilling machines. Continuous tunneling machinery is categorized by rock-breaking methods into cross-section and full-section types. Cross-section machinery primarily includes disc cutters, jib-type, pendulum-type, and impact-type. Full-section machinery mainly consists of support-type and shield-type.
