Description

technical field

[0001] The invention belongs to the field of civil engineering, and in particular relates to a large-scale comprehensive simulation drilling test platform and a method in an engineering geological parameter prediction room. Background technique

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Drilling into rocks is often encountered in engineering. For example, in tunnel construction, there are a large number of rocks in the tunnel, which are easily encountered by drilling machines.

[0004] In practical engineering applications, rock drillability is usually used as a quantitative index to judge the rock's ability to resist mechanical crushing during drilling. It is the current engineering drilling method to select drilling methods, drill bit structure types, drilling process parameters, measure drilling speed and implement quotas. main basis for manage...
