An excavation system employing a high-pressure pulsed air jet that may optionally be used in combination with a low-pressure high velocity blower for excavating improvised explosive devices or other buried objects. The excavation system may also be employed to operate a pneumatic tool such as a cut-off tool or a chisel. The high velocity blower may incorporate a bifurcated fan duct having two air outlets. The system may include a pressure control module for regulating the from a high-pressure air source to an evacuation valve. The evacuation valve employs first and second valves where the second valve controls the operation of the first valve.

An excavation control system includes a working unit, hydraulic cylinders, a prospective speed obtaining part, a relative speed obtaining part, a speed limit selecting part and a hydraulic cylinder controlling part. The prospective speed obtaining part obtains first and second prospective speeds depending on first and second intervals between first and second monitoring points of the bucket and a designed surface, respectively. The relative speed obtaining part obtains first and second relative speeds of the first and second monitoring points relative to the designed surface, respectively. The speed limit selecting part selects one of the first and second prospective speeds as a speed limit based on relative relations between the first and second relative speeds and the first and second prospective speeds, respectively. The hydraulic cylinder controlling part limits a relative speed of one of the first and second monitoring points to the speed limit.

A planning and guiding method and excavation guiding device correctly implant an artificial tooth root at a predetermined site, perform various excavation processes on a cortical bone section and a spongy bone section by stage-based guidance, and guide eccentric excavation of the cortical bone section and concentric excavation of the spongy bone section according to a bone pattern, such that the artificial tooth root thus implanted is not only positioned at a planned ideal site but also manifests appropriate initial stability.
